Connecticut Appellate Court · decided 2024-09-17

The defendant appealed from the judgments of the trial court following his convictions of several weapons related charges. He claimed that the trial court improperly denied his motions to dismiss and to suppress because it had incorrectly determined that the applicable statutes (§§ 53-202b, 53-202w and 53a-211) did not violate his second amendment right to bear arms. Held: The trial court applied an incorrect legal standard in denying the defendant's motions to dismiss and to suppress; accordingly, this court reversed the judgments and remanded the cases to the trial court for reconsideration of the defendant's motions under the standard announced in New York State Rifle & Pistol Assn., Inc. v. Bruen (597 U.S. 1). In adjudicating the defendant's as applied constitutional challenge on remand, the trial court was directed to apply the text and history test set forth in Bruen, under which the defendant bears the initial burden to show that the plain text of the second amendment presumptively protects his right to keep and bear the items at issue. This court directed that, if the trial court finds that the second amendment presumptively protects the defendant's conduct, the state then bears the burden to establish the constitutionality of the statutes at issue through historical analogues of firearm regulation that imposed a comparable burden that is comparably justified.

         STATE OF CONNECTICUT v. MICHAEL GIANNONE
                        (AC 46008)
                           Bright, C. J., and Clark and Seeley, Js.

                                           Syllabus

         The defendant appealed from the judgments of the trial court following his
         convictions of several weapons related charges. He claimed that the trial
         court improperly denied his motions to dismiss and to suppress because it
         had incorrectly determined that the applicable statutes (§§ 53-202b, 53-202w
         and 53a-211) did not violate his second amendment right to bear arms. Held:

         The trial court applied an incorrect legal standard in denying the defendant’s
         motions to dismiss and to suppress; accordingly, this court reversed the
         judgments and remanded the cases to the trial court for reconsideration of
         the defendant’s motions under the standard announced in New York State
         Rifle & Pistol Assn., Inc. v. Bruen (
597 U.S. 1
).

         In adjudicating the defendant’s as applied constitutional challenge on
         remand, the trial court was directed to apply the text and history test set
         forth in Bruen, under which the defendant bears the initial burden to show
         that the plain text of the second amendment presumptively protects his
         right to keep and bear the items at issue.

         This court directed that, if the trial court finds that the second amendment
         presumptively protects the defendant’s conduct, the state then bears the
         burden to establish the constitutionality of the statutes at issue through
         historical analogues of firearm regulation that imposed a comparable burden
         that is comparably justified.

       judicial district of Danbury, where the court, Pavia,
       J., denied the defendant’s motions to dismiss and to
       suppress certain evidence; thereafter, the defendant
       was presented to the court, D’Andrea, J., on conditional
       pleas of nolo contendere to two counts each of sale of
       an assault weapon, possession of a silencer and possession of a large capacity magazine; judgments of guilty
       in accordance with the pleas; subsequently, the state

                                        Opinion

         BRIGHT, C. J. The defendant, Michael Giannone,
       appeals from the judgments of conviction rendered by
       the trial court following his conditional pleas of nolo
       contendere to two counts each of sale of an assault
       weapon in violation of General Statutes § 53-202b (a)
       (1), possession of a silencer in violation of General
       Statutes § 53a-211, and possession of a large capacity
       magazine in violation of General Statutes § 53-202w (c)
       (2). On appeal, the defendant claims that the court
       improperly denied his motion to dismiss the charges
       against him and his motion to suppress evidence seized
       by the police because the statutes under which he was
       convicted violate his right to bear arms under the second amendment to the United States constitution.1 In
         1
          In his principal brief on appeal, the defendant phrases the sole issue as
       whether his convictions violate the second amendment. The issue is more
       properly stated as whether the trial court improperly denied his motion to
       dismiss and motion to suppress because, pursuant to General Statutes § 54-

         light of the United States Supreme Court’s recent decision in New York State Rifle & Pistol Assn., Inc. v.
         Bruen, 
597 U.S. 1
, 
142 S. Ct. 2111
, 
213 L. Ed. 2d 387
         (2022), which was issued after the trial court denied
         the defendant’s motions but prior to his sentencing, we
         conclude that the judgments of the trial court must be
         reversed and the cases remanded for an evidentiary
         hearing on the defendant’s motions. In addition, we
         provide guidance to the trial court regarding how it
         should analyze the claims raised in the defendant’s
         motions under Bruen.

            The following undisputed facts and procedural history are relevant to the present appeal. In March, 2016,
         a confidential source informed the state police that the
         defendant was selling AR-15 style rifles2 without serial
         numbers and without proper documentation. An undercover detective subsequently conducted two controlled
         firearm purchases from the defendant at the defendant’s
         residence in New Fairfield during the weeks of March 13
         94a, those are the only issues that this court may consider on appeal. See
         footnote 10 of this opinion.
            Additionally, we note that, although the defendant filed memoranda of
         law in support of both motions, his memorandum of law in support of the
         motion to suppress simply restated the basis for his motion to suppress and
         adopted the memorandum of law in support of the motion to dismiss.
         Furthermore, the trial court addressed these motions together, with the
         heading of the court’s memorandum of decision stating that it pertains to
         the ‘‘motion to suppress/dismiss.’’ Because the parties’ arguments and the
         court’s analysis of the defendant’s second amendment claims are the same
         as to both motions, we address the defendant’s claim on appeal as pertaining
         to both motions.

              The United States Supreme Court has described the AR-15 as ‘‘the civilian
         version of the military’s M-16 rifle,’’ noting that, ‘‘unless modified, [it is] a
         semiautomatic weapon.’’ Staples v. United States,

       and 20, 2016. During the first transaction, the detective
       purchased from the defendant an AR-15 style semiautomatic .223 caliber assault rifle with a pistol grip, collapsible stock, and flash suppressor, bearing no serial number, and a thirty round large capacity magazine in
       exchange for $800. During the second transaction, the
       undercover detective purchased from the defendant
       another AR-15 style semiautomatic .223 caliber assault
       rifle with a pistol grip, collapsible stock, flash suppressor, and approximately 10.5 inch barrel, also bearing no
       serial number, and another thirty round large capacity
       magazine in exchange for $800. No paperwork was completed or transferred regarding either sale. In connection with these two transactions, in Docket No. CR-16-
       153002-S, the state charged the defendant in a March
       23, 2016 information with, inter alia, two counts of sale
       of an assault weapon in violation of § 53-202b (a) (1).3
       As a result of the seizure by the police of various firearm
       related items while executing a search warrant at the
       defendant’s residence, the state also charged the defendant in a June 14, 2016 substitute information in Docket
       No. CR-XX-XXXXXXX-S with, inter alia, three counts of
       possession of a silencer in violation of § 53a-2114 and
       sixty-five counts of possession of a large capacity magazine in violation of § 53-202w (c) (2).5

           General Statutes § 53-202b (a) (1) provides: ‘‘Any person who, within
       this state, distributes, transports or imports into the state, keeps for sale,
       or offers or exposes for sale, or who gives any assault weapon, except as
       provided by sections 53-202a to 53-202k, inclusive, shall be guilty of a class
       C felony and shall be sentenced to a term of imprisonment of which two
       years may not be suspended or reduced by the court.’’
         Pursuant to General Statutes § 53-202a (1) (B) (xx), ‘‘assault weapon’’
       includes, among others, AR-15 ‘‘semiautomatic centerfire rifles, or copies
       or duplicates thereof with the capability of any such rifles . . . .’’

           General Statutes § 53a-211 provides in relevant part: ‘‘(a) A person is

                                       State v. Giannone

            On January 2, 2019, the defendant filed a motion to
         dismiss the charges against him and a motion to suppress the seized evidence. He filed memoranda of law
         in support of both motions, in which he argued that
         the statutes under which he was charged violate his
         right to bear arms under the second amendment to the
         United States constitution and article first, § 15, of the
         Connecticut constitution. The state filed a memorandum of law in opposition to the defendant’s motions
         on February 4, 2019. Without a hearing,6 the court,
         Pavia, J., subsequently denied the defendant’s motions
         in a June 12, 2019 memorandum of decision,7 concluding
         that the statutes at issue did not unconstitutionally
         infringe on the defendant’s right to bear arms as guaranteed by the state and federal constitutions. In reaching
         that conclusion, the court applied the pre-Bruen two
         step approach that the United States Court of Appeals
         for the Second Circuit and several other federal circuit
         courts adopted following the United States Supreme
         Court’s decisions in District of Columbia v. Heller,

         2015), cert. denied sub nom. Shew v. Malloy, 
579 U.S. 6
             During a court proceeding on January 10, 2019, after setting a deadline
         for the state to file a response to the defendant’s motions, the court noted
         that it was ‘‘probably [going to] need [to hold] a hearing’’ on those motions.
         The following colloquy then occurred between the court and the prosecutor:
           ‘‘[The Prosecutor]: I don’t think it’s an evidentiary, I think it’s just more—
           ‘‘The Court: More of an argument—
           ‘‘[The Prosecutor]: —you can take on the papers. Yes.
           ‘‘The Court: —okay.’’
           Defense counsel did not argue that an evidentiary hearing was necessary.
         Moreover, there is no indication in the record, including in the court’s
         memorandum of decision, that the court held a hearing at which evidence
         or argument was presented on the defendant’s motions.
           7
             Although the court indicated in its memorandum of decision that the
         motion to suppress ‘‘is addressed in a separate ruling,’’ there is no separate
         ruling in the record. See footnote 1 of this opinion.

 (2016). That two
       step framework required a court first to assess whether
       the challenged statute burdened conduct protected by
       the second amendment. Id., 254. If the first step was
       satisfied, the court would move to the second step of
       the inquiry, at which it would ‘‘[evaluate] the law under
       some form of means-end scrutiny. If the law passe[d]
       muster under that standard, it [was] constitutional. If
       it fail[ed], it [was] invalid.’’ (Internal quotation marks
       omitted.) State v. DeCiccio, 
315 Conn. 79
, 111, 
105 A.3d 165
 (2014). In DeCiccio, our Supreme Court concluded
       that intermediate scrutiny applied in the second amendment context; 
id., 142
; which required the state to ‘‘demonstrate that the [firearms regulation at issue] [was]
       substantially related to an important government objective.’’8 (Internal quotation marks omitted.) 
Id., 143
.
         In the present cases, the trial court’s analysis focused
       almost exclusively on the second step of the pre-Bruen
       test. Applying the intermediate scrutiny means-end test
         8
           The United States Supreme Court acknowledged in Bruen that ‘‘[s]tep
       one of the predominant framework [was] broadly consistent with Heller’’;
       New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 19
; and
       that its decision in Bruen was merely applying the text and history test set
       forth in Heller. See 
id., 26
. Therefore, as other courts have recognized, pre-Bruen decisions applying Heller have at least some relevance following
       Bruen to the extent that they are consistent with the text and history test
       established in Heller and clarified in Bruen. See, e.g., Hanson v. District
       of Columbia, 
671 F. Supp. 3d 1
, 8 (D.D.C. 2023) (Bruen’s ‘‘first step is
       consistent with the first step of [c]ourts of [a]ppeals’ decisions pre-Bruen.
       In other words, Bruen did not disturb the analysis [c]ourts of [a]ppeals
       conducted under the first step of their framework. . . . The [c]ourt will
       therefore . . . accord [the step one] analysis [in those pre-Bruen cases]
       persuasive weight to the extent they are instructive.’’ (Citation omitted.)),
       appeal filed (D.C. Cir. May 17, 2023) (No. 23-7061); see also United States
       v. Kirby, Docket No. 3:22-cr-26-TJC-LLL,

 (11th Cir. June 5, 2024), petition for cert. filed (U.S. September 4,

       DeCiccio in this opinion to the extent that we find that it is consistent
       with Bruen.

         must therefore evaluate whether the challenged statutes in the present cases bear a substantial relationship
         to the achievement of this governmental objective. It
         is important to note that none of the charged offenses
         bar the defendant from enjoying his constitutionally
         protected second amendment rights. The defendant has
         a legal means to avail himself of his right to bear arms.
         See Benjamin v. Bailey, 
234 Conn. 455, 471
, [
662 A.2d 1226
] (1995) (a statutory ban on assault weapons does
         not impair the right to bear arms, as it continues to
         permit access to a wide array of weapons). The government, however, has an interest in the protection of
         society, and this interest is substantially furthered by
         reducing access to, and in restricting the transfer of,
         assault weapons and large capacity magazines. [Id.,
         467.] (courts have overwhelmingly recognized that the
         right to bear arms is not infringed by reasonable regulation by the state in the exercise of its police power to
         protect the health, safety and morals of the citizenry).
         This stands particularly true in weapons that are void
         of any traceable and identifying markings. As such, the
         court finds that the statutes in question in the present
         matter do not infringe upon the defendant’s right to
         bear arms as guaranteed by the United States and Connecticut constitutions.’’ (Footnote omitted; internal

                                     State v. Giannone

          Following the court’s denial of the defendant’s
       motions to dismiss and to suppress, the state filed a
       substitute information in Docket No. CR-XX-XXXXXXX-S
       on May 3, 2022, charging him with, inter alia, two counts
       each of sale of an assault weapon and possession of
       a large capacity magazine. The defendant thereafter
       entered pleas of nolo contendere to two counts of sale
       of an assault weapon, two counts of possession of a
       silencer,9 and two counts of possession of a large capacity magazine, conditioned on his right to appeal from
       the court’s rulings on his motion to dismiss and motion
       to suppress. See General Statutes § 54-94a.10 After the
       court ruled on the defendant’s motions, but prior to his
       sentencing, the United States Supreme Court issued its
       decision in New York State Rifle & Pistol Assn., Inc.
       v. 
Bruen, supra,
 
597 U.S. 1
. In Bruen, the Supreme
          9
            The trial court record inconsistently describes the silencer charge. For
       instance, the judgments of the trial court, D’Andrea, J., setting forth the
       defendant’s sentences describe the offense both as ‘‘possession of sawed
       off shotgun/silencer in violation of . . . § 53a-211’’ and ‘‘possession of a
       silencer in violation of . . . § 53a-211,’’ which statute prohibits the possession of both silencers and sawed-off shotguns. We also observe that Judge
       Pavia’s memorandum of decision denying the defendant’s motions to dismiss
       and to suppress notes that ‘‘[t]he defendant stands charged with the crimes
       of firearms trafficking, illegal sale of an assault weapon, illegal possession
       of an assault weapon, illegal possession of a large capacity magazine, [and]
       possession of a sawed-off shotgun’’ but not that the defendant was charged
       with the crime of possession of a silencer. The substitute information that the
       state filed in Docket No. CR-XX-XXXXXXX-S, however, describes the relevant
       charge as ‘‘possession of a silencer (three counts)’’ in violation of § 53a-
       211. We rely on the information as an accurate statement of the charges
       against the defendant.
          10
             General Statutes § 54-94a provides in relevant part: ‘‘When a defendant,
       prior to the commencement of trial, enters a plea of nolo contendere conditional on the right to take an appeal from the court’s denial of the defendant’s
       motion to suppress or motion to dismiss, the defendant after the imposition
       of sentence may file an appeal within the time prescribed by law provided
       a trial court has determined that a ruling on such motion to suppress or
       motion to dismiss would be dispositive of the case. The issue to be considered in such an appeal shall be limited to whether it was proper for the
       court to have denied the motion to suppress or the motion to dismiss. . . .’’

         Court expressly rejected the Second Circuit’s two step
         framework, which the trial court applied in the present
         cases. See id., 19. The Supreme Court, instead, clarified
         and applied ‘‘Heller’s text-and-history standard’’; id., 39;
         which the court emphasized did not involve the means-end balancing that the trial court had applied in the
         present cases. See id., 19.
           Despite the Supreme Court’s decision in Bruen, the
         defendant did not ask the trial court to reconsider his
         motions to suppress and to dismiss. Accordingly, on
         September 2, 2022, the court, D’Andrea, J., sentenced
         the defendant to a total effective term of ten years of
         incarceration, execution suspended after three years,
         with five years of probation.11 This appeal followed.
                                                I
           On appeal, the defendant claims that the Supreme
         Court’s decision in Bruen ‘‘has revolutionized courts’
         analysis of firearms laws.’’ The defendant argues that
         the proper application of the Bruen analysis in the
         present cases leads to the conclusion that the statutes
         under which the defendant was convicted are unconstitutional as applied to him,12 and his convictions therefore must be vacated. The state acknowledges that
           11
               Specifically, the trial court sentenced the defendant as follows: (1) on
         each of the two counts of sale of an assault weapon, ten years of incarceration, execution suspended after three years, with five years of probation
         with special conditions, and deadly weapon offender registration; (2) on
         each of the two counts of possession of a silencer, five years of incarceration,
         execution suspended after three years, with five years of probation with
         special conditions, and deadly weapon offender registration; and (3) on
         each of the two counts of illegal possession of a large capacity magazine,
         five years of incarceration, execution suspended after three years, with five
         years of probation with special conditions and deadly weapon offender
         registration. The sentences were to run concurrently with each other for a
         total effective sentence of ten years of incarceration, execution suspended
         after three years, two of which were a mandatory minimum. The state
         entered a nolle prosequi as to all remaining counts.
            12
               During oral argument before this court, the state argued that the defendant’s claims were facial challenges to the statutes at issue. We do not
         construe his claims that way. Although, in his principal and reply briefs on

       Bruen explicitly rejected the means-end analysis that
       the trial court had applied in the present cases but
       argues that Bruen did not materially alter the manner
       in which courts apply the second amendment to restrictions on certain types of weapons. Consequently, the
       state argues that the trial court correctly concluded
       that the statutes under which the defendant was convicted are constitutional.

         To provide context for our analysis of Bruen’s impact
       on the present dispute, we begin with a review of the
       development of second amendment law, starting with
       the United States Supreme Court’s seminal decision in
       appeal, the defendant refers to the regulated firearms generally as ‘‘assault
       weapons’’ or ‘‘semiautomatic rifles,’’ suggesting that his challenge to General
       Statutes § 53-202a may not be limited to the prohibition on the sale of the
       particular AR-15 style rifles at issue in the present cases, the defendant does
       not argue that the statutes at issue are unconstitutional as applied to each
       of the specific firearms enumerated in those statutes. See General Statutes
       § 53a-211 (banning, in addition to silencers, sawed-off shotguns) and General
       Statutes § 53-202a (enumerating various types of assault weapons, including
       both semiautomatic and fully automatic firearms, including, but not limited
       to, AR-15s, that fall within statutory definition of ‘‘assault weapon’’). Such
       a showing is required to prevail on a facial challenge under Bruen. See
       United States v. Rahimi,          U.S.     , 
144 S. Ct. 1889
, 1898, 
219 L. Ed. 2d 351
 (2024) (facial challenge ‘‘requires a defendant to establish that no set
       of circumstances exists under which the [statute] would be valid’’ (emphasis
       added; internal quotation marks omitted)); see also National Assn. for Gun
       Rights v. Lamont, 
685 F. Supp. 3d 63
, 92 (D. Conn. 2023) (plaintiffs raising
       facial challenge to assault weapon ban on ‘‘specific firearms of enumerated
       models and features,’’ as opposed to a complete ban on ‘‘all semiautomatic
       rifles, or . . . semiautomatic handguns,’’ had burden ‘‘to present evidence
       regarding the specific assault weapons enumerated in the [c]hallenged [s]tatutes’’ (emphasis in original)). Moreover, the defendant’s counsel indicated
       during oral argument before this court that each of his claims ‘‘could be’’
       and ‘‘probably [are]’’ as applied challenges. Consequently, we construe the
       defendant’s claim as to each statute to be that it is unconstitutional as
       applied to the particular facts of his cases. We do not, however, intend
       to preclude the defendant from arguing on remand that the statutes are
       unconstitutional on their face, in which case he will bear a much heavier
       burden. See United States v. Rahimi, supra, 1898 (facial challenge is ‘‘most
       difficult challenge to mount successfully’’ (internal quotation marks omitted)).

          District of Columbia v. 
Heller, supra,
 
554 U.S. 570
. ‘‘In
          Heller, the United States Supreme Court was called on
          to determine the constitutionality of District of Columbia ordinances that broadly prohibited the possession
          of handguns, in the home and elsewhere; see 
id.,
 574–76;
          and also required citizens to ‘keep their lawfully owned
          firearms, such as registered long guns, ‘‘unloaded and
          disassembled or bound by a trigger lock or similar
          device’’ unless they are located in a place of business
          or are being used for lawful recreational activities.’ 
Id., 575
. In determining whether the second amendment
          confers an individual right to possess arms and, if so, the
          scope of such a right, the court conducted an extensive
          textual and historical analysis of the second amendment, which provides: ‘A well regulated Militia, being
          necessary to the security of a free State, the right of
          the people to keep and bear Arms, shall not be
          infringed.’ U.S. Const., amend. II.’’ (Footnote omitted.)
          State v. DeCiccio, supra, 315 Conn. 108–109. As to the
          meaning of ‘‘[a]rms’’ in the second amendment, the
          court in Heller stated that ‘‘[t]he 18th-century meaning
          is no different from the meaning today.’’ District of
          Columbia v. 
Heller, supra, 581
. The court referenced
          both a 1773 dictionary, which defined ‘‘arms’’ as
          ‘‘[w]eapons of offence, or armour of defence,’’ and a
          1771 legal dictionary, which defined that term as ‘‘any
          thing that a man wears for his defence, or takes into
          his hands, or useth in wrath to cast at or strike another.’’

Id.
             In DeCiccio, our Supreme Court stated: ‘‘Upon examining the prefatory and operative clauses of the second

          concluded that it ‘guarantee[s] the individual right to

            13
               ‘‘The court emphasized that its reading of the operative clause in this

                                    State v. Giannone

       
Id., 592
. The court observed, however, that this right is
       ‘not unlimited, just as the [f]irst [a]mendment’s right of
       free speech [is] not . . . . Thus, [the court] do[es] not
       read the [s]econd [a]mendment to protect the right of
       citizens to carry arms for any sort of confrontation, just
       as [the court] do[es] not read the [f]irst [a]mendment
       to protect the right of citizens to speak for any purpose.’
       . . . 
Id., 595
. After considering the parameters of the
       second amendment right, the court held that it does
       protect the possession of ‘weapons . . . typically possessed by law-abiding citizens for lawful purposes’; 
id., 625
; and does not protect ‘dangerous and unusual weapons.’ . . . 
Id., 627
. The court further concluded that
       the District of Columbia’s firearms ordinances violated
       ‘the inherent right of self-defense [that] has been central
       to the [s]econd [a]mendment right. The handgun ban
       amounts to a prohibition of an entire class of arms that
       is overwhelmingly chosen by American society for that
       lawful purpose. The prohibition extends, moreover, to
       the home, where the need for defense of self, family,
       and property is most acute. Under any of the standards
       of scrutiny that we have applied to enumerated constitutional rights, banning from the home the most preferred
       firearm in the nation to keep and use for protection of
       one’s home and family . . . would fail constitutional
       muster.’ . . . 
Id.,
 628–29.
         ‘‘Two years later, the United States Supreme Court
       considered whether the second amendment right to
       keep and bear arms is incorporated in the concept of
       announces the purpose for which the right was codified: to prevent elimination of the militia. The prefatory clause does not suggest that preserving
       the militia was the only reason Americans valued the ancient right; most
       undoubtedly thought it even more important for self-defense and hunting.
       But the threat that the new [f]ederal [g]overnment would destroy the citizens’
       militia by taking away their arms was the reason that right—unlike some
       other English rights—was codified in a written [c]onstitution.’ District of

          the fourteenth amendment. See McDonald v. 
Chicago, supra,
 
561 U.S. 750
. The court in McDonald explained
          that its ‘decision in Heller points unmistakably to the
          answer. Self-defense is a basic right, recognized by
          many legal systems from ancient times to the present
          day, and, in Heller, [the court] held that individual self-defense is the central component of the [s]econd

Id., 767
. Following a detailed
          historical analysis; see generally 
id.,
 768–77; the court
          concluded that the second amendment is applicable to
          the states because ‘the [f]ramers and ratifiers of the
          [f]ourteenth [a]mendment counted the right to keep and
          bear arms among those fundamental rights necessary
          to our system of ordered liberty.’

.’’ (Footnote
          in original.) State v. DeCiccio, supra, 315 Conn. 109–11.
             Then came Bruen. Nearly fifteen years after Heller
          was decided, the United States Supreme Court considered a challenge to a New York statute that required a
          handgun owner to demonstrate ‘‘ ‘proper cause’ ’’ to
          acquire a permit to carry a handgun in public. See New
          York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
          
597 U.S. 12
. The court began its analysis by summarizing
          its prior holdings and how those holdings had been
          applied: ‘‘In Heller and McDonald, we held that the
          [s]econd and [f]ourteenth [a]mendments protect an
          individual right to keep and bear arms for self-defense.
          In doing so, we held unconstitutional two laws that
          prohibited the possession and use of handguns in the
          home. In the years since, the [c]ourts of [a]ppeals have
          coalesced around a two-step framework for analyzing
          [s]econd [a]mendment challenges that combines history with means-end scrutiny. . . .
             ‘‘At the first step, the government may justify its regulation by establish[ing] that the challenged law regulates
          activity falling outside the scope of the right as originally
          understood. E.g., Kanter v. Barr, 
919 F.3d 437, 441
 (7th

                             State v. Giannone

       Cir. 2019) . . . . But see United States v. Boyd, 
999 F.3d 171, 185
 (3d Cir. 2021) (requiring claimant to show
       a burden on conduct falling within the scope of the
       [s]econd [a]mendment’s guarantee). The [c]ourts of
       [a]ppeals then ascertain the original scope of the right
       based on its historical meaning. . . . If the government
       can prove that the regulated conduct falls beyond the
       [a]mendment’s original scope, then the analysis can
       stop there; the regulated activity is categorically unprotected. . . . But if the historical evidence at this step
       is inconclusive or suggests that the regulated activity
       is not categorically unprotected, the courts generally
       proceed to step two. . . .
          ‘‘At the second step, courts often analyze how close
       the law comes to the core of the [s]econd [a]mendment
       right and the severity of the law’s burden on that right.
       . . . The [c]ourts of [a]ppeals generally maintain that
       the core [s]econd [a]mendment right is limited to self-defense in the home. . . . If a core [s]econd [a]mendment right is burdened, courts apply strict scrutiny and
       ask whether the [g]overnment can prove that the law is
       narrowly tailored to achieve a compelling governmental
       interest. . . . Otherwise, they apply intermediate scrutiny and consider whether the [g]overnment can show
       that the regulation is substantially related to the
       achievement of an important governmental interest.’’

       McDonald do not support applying means-end scrutiny
       in the [s]econd [a]mendment context. Instead, the government must affirmatively prove that its firearms regulation is part of the historical tradition that delimits the
       outer bounds of the right to keep and bear arms.’’

          plain text covers an individual’s conduct, the [c]onstitution presumptively protects that conduct. To justify its
          regulation, the government may not simply posit that
          the regulation promotes an important interest. Rather,
          the government must demonstrate that the regulation
          is consistent with this [n]ation’s historical tradition of
          firearm regulation. Only if a firearm regulation is consistent with this [n]ation’s historical tradition may a
          court conclude that the individual’s conduct falls outside the [s]econd [a]mendment’s unqualified command.’’ (Emphasis added; internal quotation marks
          omitted.) 
Id., 17
. In Bruen, the court emphasized that
          it was doing no more than applying Heller’s ‘‘straightforward historical inquiry’’ to New York’s proper cause
          requirement. 
Id., 27
. Thus, ‘‘[f]ollowing the course
          charted by Heller, [the court] consider[ed] whether historical precedent from before, during, and even after
          the founding evince[d] a comparable tradition of regulation.’’ (Internal quotation marks omitted.) 
Id.
             The court recognized, though, that before considering
          whether a particular regulation falls within the nation’s
          historical tradition, it first had to determine whether the
          second amendment’s plain text covered the individual’s
          conduct. The conduct in Bruen was ‘‘carrying handguns
          publicly for self-defense.’’ 
Id., 32
. Again, the court relied
          on Heller as its lodestar to guide its analysis: ‘‘We have
          already recognized in Heller at least one way in which
          the [s]econd [a]mendment’s historically fixed meaning
          applies to new circumstances: Its reference to arms
          does not apply only [to] those arms in existence in the
          18th century. [District of Columbia v. 
Heller, supra,
          
554 U.S. 582
]. Just as the [f]irst [a]mendment protects
          modern forms of communications, and the [f]ourth
          [a]mendment applies to modern forms of search, the
          [s]econd [a]mendment extends, prima facie, to all
          instruments that constitute bearable arms, even those
          that were not in existence at the time of the founding.

       [Id.] . . . Thus, even though the [s]econd [a]mendment’s definition of arms is fixed according to its historical understanding, that general definition covers modern instruments that facilitate armed self-defense.’’

       Rifle & Pistol Assn., Inc. v. 
Bruen, supra,

. The court further explained that, in Heller, ‘‘[a]fter
       holding that the [s]econd [a]mendment protected an
       individual right to armed self-defense, we also relied
       on the historical understanding of the [a]mendment to
       demark the limits on the exercise of that right. We noted
       that, [l]ike most rights, the right secured by the [s]econd
       [a]mendment is not unlimited. [District of Columbia v.
       
Heller, supra, 626
.] From Blackstone through the 19th-century cases, commentators and courts routinely
       explained that the right was not a right to keep and carry
       any weapon whatsoever in any manner whatsoever and
       for whatever purpose. [Id.] For example, we found it
       fairly supported by the historical tradition of prohibiting
       the carrying of dangerous and unusual weapons that
       the [s]econd [a]mendment protects the possession and
       use of weapons that are in common use at the time.
       [Id., 627] . . . .’’ (Internal quotation marks omitted.)

Bruen, supra, 21
.

          In Heller and Bruen, the court easily concluded that
       handguns were arms within the meaning of the second
       amendment. As the court stated in Heller, ‘‘the inherent
       right of self-defense has been central to the [s]econd
       [a]mendment right. The handgun ban amounts to a prohibition of an entire class of ‘arms’ that is overwhelmingly chosen by American society for that lawful purpose.’’ District of Columbia v.

          for self-defense,’’ and court had ‘‘little difficulty concluding that’’ second amendment’s plain text protects
          right to carry handguns publicly for self-defense (internal quotation marks omitted)).
             Having concluded in Heller and Bruen that the plain
          text of the second amendment protects the right to
          keep and bear handguns for self-defense, the court then,
          in each case, assessed whether there were any analogous historical regulations that justified the handgun
          regulation at issue. In Bruen, in an effort to make ‘‘the
          constitutional standard endorsed in Heller more
          explicit’’; New York State Rifle & Pistol Assn., Inc. v.
          
Bruen, supra,
 
597 U.S. 31
; the court explained the process as follows: ‘‘Much like we use history to determine
          which modern arms are protected by the [s]econd
          [a]mendment, so too does history guide our consideration of modern regulations that were unimaginable
          at the founding. When confronting such present-day
          firearm regulations, this historical inquiry that courts
          must conduct will often involve reasoning by analogy—
          a commonplace task for any lawyer or judge. Like all
          analogical reasoning, determining whether a historical
          regulation is a proper analogue for a distinctly modern
          firearm regulation requires a determination of whether
          the two regulations are relevantly similar. . . . And
          because [e]verything is similar in infinite ways to everything else . . . one needs some metric enabling the
          analogizer to assess which similarities are important
          and which are not . . . . For instance, a green truck
          and a green hat are relevantly similar if one’s metric is
          things that are green. . . . They are not relevantly similar if the applicable metric is things you can wear.
             ‘‘While we do not now provide an exhaustive survey
          of the features that render regulations relevantly similar
          under the [s]econd [a]mendment, we do think that
          Heller and McDonald point toward at least two metrics:

                                   State v. Giannone

       how and why the regulations burden a law-abiding citizen’s right to armed self-defense.’’ (Citations omitted;
       internal quotation marks omitted.) 
Id.,
 28–29. The court
       then looked to the history of public carry regulations
       from the late 1200s to the early 1900s. See 
id., 34
. The
       court cautioned, however, that ‘‘[h]istorical evidence
       that long predates either [the adoption of the second
       amendment in 1791 or of the fourteenth amendment in
       1868] may not illuminate the scope of the right if linguistic or legal conventions changed in the intervening
       years. . . . Similarly, we must also guard against giving
       postenactment history more weight than it can rightly
       bear. . . . [T]o the extent later history contradicts
       what the text says, the text controls.’’14 (Citations omitted.) 
Id.,
 34–36.
         After a ‘‘long journey through the Anglo-American
       history of public carry,’’ the court in Bruen concluded
       that the ‘‘respondents [had] not met their burden to
       identify an American tradition justifying the [s]tate’s
       proper-cause requirement. . . . Apart from a few late-
       19th-century outlier jurisdictions, American governments simply have not broadly prohibited the public
       carry of commonly used firearms for personal defense.
       Nor, subject to a few late-in-time outliers, have American governments required law-abiding, responsible citizens to demonstrate a special need for self-protection
       distinguishable from that of the general community in
       order to carry arms in public.’’ (Citation omitted; internal quotation marks omitted.) 
Id., 70
. The court consequently held that ‘‘New York’s proper-cause requirement violates the [f]ourteenth [a]mendment in that it
       prevents law-abiding citizens with ordinary self-defense
       needs from exercising their right to keep and bear
       arms.’’ 
Id., 71
.
         14
            The court in Bruen ‘‘acknowledge[d] that there is an ongoing scholarly
       debate on whether courts should primarily rely on the prevailing understanding of an individual right when the [f]ourteenth [a]mendment was ratified
       in 1868 when defining its scope (as well as the scope of the right against
       the [f]ederal [g]overnment).’’ New York State Rifle & Pistol Assn., Inc. v.

                                       State v. Giannone

             Recently, the United States Supreme Court again
          addressed the scope of the second amendment in
          United States v. Rahimi,         U.S.     , 
144 S. Ct. 1889
,
          
219 L. Ed. 2d 351
 (2024), in which it provided some
          clarification of the Bruen test. Rahimi involved a second amendment challenge to ‘‘[a] federal statute [that]
          prohibits an individual subject to a domestic violence
          restraining order from possessing a firearm if that order
          includes a finding that he represents a credible threat
          to the physical safety of [an] intimate partner, or a child
          of the partner or individual.’’ (Internal quotation marks
          omitted.) Id., 1894. An eight person majority of the
          court, after considering regulations on the possession
          of weapons by those who pose a threat to others ‘‘[f]rom
          the earliest days of the common law’’; id., 1899; to the
          early 1800s, had ‘‘no trouble concluding that [the statute] survive[d] [the defendant’s] facial challenge. Our
          tradition of firearm regulation allows the [g]overnment
          to disarm individuals who present a credible threat to
          the physical safety of others. [The statute] can be
          applied lawfully to [the defendant].’’ Id., 1902. In reaching this conclusion, the court in Rahimi explained that,
          ‘‘when a challenged regulation does not precisely match
          its historical precursors, it still may be analogous
          enough to pass constitutional muster.’’ (Internal quotation marks omitted.) Id., 1898.

             Accordingly, under Bruen, a court asks first whether
          the second amendment’s plain text covers the conduct
          at issue. New York State Rifle & Pistol Assn., Inc. v.
          
Bruen, supra,
 
597 U.S. 32
. If so, that conduct is presumptively protected, and the court proceeds to the second
          step, at which it asks whether the government has satis-
          
Bruen, supra,
 
597 U.S. 37
. The court did not settle that issue because ‘‘the
          public understanding of the right to keep and bear arms in both 1791 and
          1868 was, for all relevant purposes, the same with respect to public carry.’’

                                     State v. Giannone

       fied its burden to identify a historical tradition justifying
       its firearm regulation.15 
Id.,
 33–34.
         Having set forth the test that the court applied in
       Bruen and having provided historical context for the
       recent developments in second amendment law, we
       turn to the test that the trial court applied in the present
       cases when it decided the defendant’s motions to dismiss and to suppress. As previously noted in this opinion, the court applied the then prevailing two step
       approach adopted by the Second Circuit, following
       Heller, to assess the defendant’s second amendment
       claims and concluded that his claims failed under the
       type of means-end balancing test that the Supreme
       Court recently rejected in Bruen. The court in the present cases therefore, through no fault of its own, did not
       apply the correct legal standard when assessing the
       merits of the second amendment claims raised in the
       defendant’s motions. Additionally, the court did not
       hold a hearing on the defendant’s motions and, therefore, did not make any factual findings that, as we will
       explain, are necessary to apply the Bruen test. See
       footnote 6 of this opinion. Accordingly, the record is
          15
             In Bruen, the court stated that the two step analytical framework that
       many courts applied following Heller was ‘‘one step too many,’’ implying
       that the Bruen test does not have two separate steps. New York State Rifle &
       Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 19
. Post-Bruen, courts have
       nonetheless interpreted the text and history test applied in Bruen as a two
       step approach that asks, first, whether the second amendment’s plain text
       protects the proposed conduct and, second, whether the regulation is nonetheless consistent with the historical tradition of firearms regulation. See,
       e.g., Bevis v. Naperville,

       but then ‘‘subbed in another two step evaluation’’ (internal quotation marks
       omitted)). Accordingly, for ease of discussion, we similarly address the
       Bruen test in two separate steps.

       that a remand might be necessary. In particular, the

       present appeal by relying on ‘‘legislative facts’’ relevant
       to whether the items at issue constitute ‘‘arms’’ under
       the second amendment, such as the Second Circuit’s
       finding in New York State Rifle & Pistol Assn., Inc.
       v. 
Cuomo, supra,
 
804 F.3d 255
, that ‘‘Americans own
       millions’’ of assault weapons, and by reviewing legislative history and analogous historical statutes. Counsel
       stated, however, that, if we find those legislative facts
       insufficient, then a remand would be appropriate. Similarly, the state’s attorney argued that we can resolve this
       appeal by adopting the factual findings and reasoning of
       other courts that have concluded that assault weapons,
       including AR-15 style rifles, large capacity magazines,
       handguns were protected ‘‘arms’’), aff’d, Docket Nos. 21-2017 and 21-2053,

          and silencers are not ‘‘arms’’ protected by the second
          amendment and that prohibitions similar to those at
          issue in the present cases are consistent with our country’s historical tradition of firearm regulation. Specifically, in its brief to this court, the state asks us to
          adopt other courts’ findings, first, as to the function
          and purpose of silencers and large capacity magazines,
          and to conclude that both are ‘‘firearm accessories’’
          unnecessary to the use of a firearm, rather than bearable
          arms protected by the second amendment. The state
          also asks us to adopt other courts’ findings as to the
          commonality, dangerousness, and militaristic character
          of AR-15 style rifles, large capacity magazines, and
          silencers, and conclude that they are not protected arms
          because they are ‘‘not commonly used or particularly
          suitable for [civilian] self-defense’’ or ‘‘have uniquely
          dangerous properties that are more properly suited for
          military use.’’ (Internal quotation marks omitted.) Additionally, the state urges us to adopt the historical analyses of other courts and to conclude that the statutes
          under which the defendant was convicted have relevant
          historical analogues that support their constitutionality.
              Given that each party asks us to accept as true certain
          proposed facts, we find that the application of Bruen
          to the conduct at issue in the present cases involves
          disputed factual questions that must be resolved by
          the trial court, before which the parties can present
          evidence that ‘‘can be explained through expert testimony and tested through cross-examination.’’ State v.

       Moreover, because the state’s brief fails to engage in
       any historical analysis beyond citing such analyses from
       other courts, we find that ‘‘[t]he parties’ briefing on
       appeal only scratches the surface of the historical analysis now required by Bruen.’’ Atkinson v. Garland, 
70 F.4th 1018, 1020
 (7th Cir. 2023). Bruen instructs that
       courts ‘‘are not obliged to sift the historical materials
       for evidence to sustain [a] statute’’; New York State
       Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 70
;
       rather, pursuant to the principle of party presentation,
       courts are ‘‘entitled to decide a [second amendment]
       case based on the historical record compiled by the
       parties.’’ 
Id.,
 26 n.6. Accordingly, we decline to resolve
       the present appeal by applying other courts’ factual
       findings and sifting through historical materials as a
       substitute for the development of an evidentiary record
       compiled by the parties, which we find is necessary to
       conduct the analysis that Bruen requires.19 We therefore
         18
            We note that the court in Kotek mentioned that ‘‘legislative facts are
       often considered by appellate courts deciding [s]econd [a]mendment challenges, see Jones v. Bonta, 
34 F.4th 704
, 726 n.24 (9th Cir. 2022), vacated,
       
47 F.4th 1124
 . . . .’’ Oregon Firearms Federation v. Kotek, supra, 
682 F. Supp. 3d 886
 n.2. In Bonta, the United States Court of Appeals for the Ninth
       Circuit considered legislative facts pertaining to the efficacy of nonsemiautomatic rifles, rimfire rifles, and shotguns for the purpose of self-defense,
       despite the plaintiffs’ failure to submit those facts below. See Jones v.
       
Bonta, supra,
 725–26 and n.24. The court considered those facts, however,
       to evaluate the severity of the burden on the second amendment right of
       home self-defense in order to determine the appropriate level of scrutiny
       to apply under the second step of the pre-Bruen test. See 
id., 726
. Moreover,
       the defendants did not contest the legislative facts presented by the plaintiffs.
       
Id.,
 726 n.24. Accordingly, Jones v. 
Bonta, supra,
 725–26, does not support
       an appellate court’s de novo resolution of disputed factual questions pertinent to Bruen’s threshold inquiry of whether the conduct at issue is protected
       by the second amendment.

             On remand, the trial court must consider evidence
          presented by the parties and make factual findings consistent with the standard set forth in Bruen.20 We recognize, however, that Bruen left several questions unanswered as to how to properly conduct its text and
          conduct covered by the plain text of the [s]econd [a]mendment, such as
          whether [large capacity magazines] are in common use today for self-defense
          by law-abiding citizens with ordinary self-defense needs . . . [and] regarding the historical record that required [the trial court] to assess witness
          credibility and bias,’’ resulting in culmination of ‘‘testimony from twenty
          witnesses’’ and ‘‘more than 100 exhibits’’ (citation omitted; internal quotation

, 189 (Pa. 2024) (acknowledging ‘‘various
       areas of uncertainty in Bruen’s method’’ and ‘‘difficulty

         Understandably, the parties in the present cases take
       different positions on what is required at several key
       points of the Bruen test, including what showing is
       required at the initial plain text inquiry and what makes

       Accordingly, we leave it to the trial court to decide whether to also seek

       amici briefs generally to assist with its inquiry on remand.
          21
             The United States Supreme Court’s recent decision in United States v.
       
Rahimi, supra,
 
144 S. Ct. 1889
, illustrates that even the members of that
       court are having difficulty agreeing on how to apply Bruen. Despite the
       near unanimous decision in Rahimi, there were five separate concurring
       opinions, in addition to a dissenting opinion. Each separate opinion provided
       either a somewhat different, or more nuanced, understanding of Bruen or
       a criticism of Bruen’s analytical approach. And, despite the court’s statement
       in Bruen that its test requires a ‘‘straightforward historical inquiry’’ involving
       ‘‘reasoning by analogy—a commonplace task for any lawyer or judge’’; New
       York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 597 U.S. 27–28; Justice
       Gorsuch acknowledged in his concurrence in Rahimi that ‘‘[d]iscerning
       what the original meaning of the [c]onstitution requires in this or that case
       may sometimes be difficult’’ and that ‘‘reasonable minds can disagree [on]
       whether [a statute] is analogous to past practices originally understood to
       fall outside the [s]econd [a]mendment’s scope . . . .’’ United States v. Rah-
       
imi, supra, 1909
 (Gorsuch, J., concurring). In fact, Justice Thomas, the
       author of the majority opinion in Bruen, was the lone dissenter in Rahimi
       because he believed that the majority improperly applied the Bruen analysis.
       See id., 1941 (Thomas, J., dissenting) (majority’s ‘‘piecemeal approach [to the
       historical analysis] is not what the [s]econd [a]mendment or our precedents
       countenance’’). Consequently, it is hardly surprising that other courts have
       struggled with how to properly apply Bruen.
Page 26                         CONNECTICUT LAW JOURNAL                                       0, 0

          a historical analogue ‘‘sufficiently analogous.’’ These
          are among the numerous questions about Bruen’s methodology that Justice Jackson recently observed remain
          ‘‘unresolved’’ following the Supreme Court’s recent
          decision in United States v. 
Rahimi, supra,
 
144 S. Ct. 1929
 (Jackson, J., concurring). Because the resolution
          of these legal questions will frame the trial court’s analysis of the defendant’s motions on remand, we provide
          some guidance on these points based on Bruen, Heller,
          and lower court decisions applying those cases. See
          Sullivan v. Metro-North Commuter Railroad Co., 
292 Conn. 150, 164
, 
971 A.2d 676
 (2009) (‘‘[b]ecause of our
          conclusion that this case must be remanded for a new
          trial, it is appropriate for us to give guidance on issues
          that are likely to recur on retrial’’); see also Atkinson
          v. 
Garland, supra,
 70 F.4th 1023–24 (setting forth questions for trial court to consider on remand to focus
          analysis under Bruen); Ward v. United States, 
318 A.3d 520
, 533 (D.C. 2024) (‘‘given the novelty of [Bruen’s]
          methodology . . . identify[ing] key steps and considerations’’ of that methodology ‘‘to limit the possibility of
          a further, avoidable remand’’).
            In short, we conclude that Bruen requires the following showing in second amendment cases.22 The initial
             22
                The defendant notes in his principal brief on appeal that he argued
          before the trial court ‘‘that his actions were protected under the second
          amendment [to the federal constitution] and article first, § 15, of the Connecticut constitution.’’ (Emphasis added.) The only further discussion of the
          state constitution in his brief is limited to recognizing that ‘‘this court has
          not yet interpreted our state constitution as granting broader rights than
          the second amendment. Instead, Connecticut has traditionally reviewed
          challenges under this provision through a balancing test . . . . A balancing
          test was rejected by Bruen as inconsistent with the second amendment.’’
          (Citation omitted.) ‘‘Because the [defendant has] furnished no reason why
          we should interpret our state constitutional provision differently than its
          federal counterpart, we construe the provisions identically for the purposes
          of this case. Cf. State v. Barnes,

       step requires that the defendant, as the party challenging the statutes at issue in the present cases, show, by
       a preponderance of the evidence, that his conduct falls
       within the plain text of the second amendment, i.e.,
       that the items at issue, first, are ‘‘arms,’’ and second,

       lawful purposes’’ (internal quotation marks omitted)).
       If the defendant makes the necessary threshold showing
       as to any of the firearms or related components at
       issue, then the plain text of the second amendment
       ‘‘presumptively protects’’ the defendant’s right to keep
       and bear that firearm or related component. New York

       The second step then requires the state to affirmatively
       prove, by presenting ‘‘relevantly similar’’ historical analogues, that its regulation of the protected ‘‘arm’’ is
       nonetheless ‘‘consistent with the [n]ation’s historical
       tradition of firearm regulation’’ and is, therefore, constitutional.

          As to Bruen’s first step, although the court in Heller
       initially stated that ‘‘the [s]econd [a]mendment extends,
       prima facie, to all instruments that constitute bearable
       arms’’; (emphasis added) District of Columbia v.

. Thus, Bruen’s threshold
          inquiry—whether the individual’s conduct falls within
          the second amendment’s plain text—necessarily
          requires a court to consider whether the item that the
          individual seeks to ‘‘keep’’ or ‘‘bear’’ is an ‘‘arm’’ that
          is entitled to second amendment protection.
             The state concedes that an AR-15 style rifle is an
          ‘‘arm,’’ and disputes neither that the defendant is one
          of ‘‘the people’’ protected by the second amendment
          nor that the defendant’s conduct in relation to the weapons at issue is covered by the second amendment. See
          New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 597 U.S. 31–32 (in relation to first step of Bruen
          test, noting that ‘‘[i]t is undisputed that [the] petitioners
          . . . two ordinary, law-abiding, adult citizens—are part
          of ‘the people’ whom the [s]econd [a]mendment protects’’ and considering ‘‘whether the plain text of the
          [s]econd [a]mendment protects [the petitioners’] proposed course of conduct—carrying handguns publicly
          for self-defense’’).23 Moreover, neither party disputes
          that the defendant bears the burden at step one to show
          that the silencers and large capacity magazines that
          he possessed are ‘‘arms.’’24 Nevertheless, the parties
          disagree on (1) whether a firearm component such as

          is part of the people whom the [s]econd [a]mendment protects, whether
          the weapon at issue is in common use today for self-defense, and whether
          the proposed course of conduct falls within the [s]econd [a]mendment’’

       (Emphasis in original.) Oregon Firearms Federation v. Kotek, supra, 888
       n.4. ‘‘This Supreme Court language strongly suggests that the burden shifts
       to the government only after the [party challenging the regulation has] shown

          show that those arms are ‘‘in common use’’ or ‘‘typically
          possessed by law-abiding citizens for lawful purposes’’
          and are not ‘‘dangerous and unusual’’ weapons, and (3)
          how a court determines whether an arm is ‘‘in common
          use’’ or ‘‘dangerous and unusual.’’ Thus, for purposes
          of applying the first step of the Bruen test in the present
          cases, we provide some guidance to assist the trial court
          in resolving these difficult questions. In doing so, we
          note that, because the defendant raises as applied challenges to the statutes at issue, he must satisfy the threshold inquiry only as to the AR-15 style rifles,25 silencers,
          and large capacity magazines that he possessed or sold,
          rather than as to all weapons prohibited by those statutes. See State v. Long, 
268 Conn. 508
, 522 n.21, 
847 A.2d 862
 (facial challenge means claim that law is ‘‘incapable of any valid application’’ and, unlike as applied
          challenge, ‘‘is not dependent on the facts of a particular
          case’’ (internal quotation marks omitted)), cert. denied,
          
543 U.S. 969
, 
125 S. Ct. 424

160 L. Ed. 2d 340
 (2004).
          As to each of the statutes at issue, if the defendant fails
          to satisfy his initial burden, then the statute stands
          because the regulated conduct falls outside of the second amendment’s scope.
                                                 1
             First, the United States Supreme Court has not yet
          squarely addressed whether firearm components qualify as ‘‘arms’’ within the meaning of the second amendment’s plain text. We nonetheless conclude that Bruen
             25
                The record does not consistently identify the type of firearms that the
          defendant was convicted of selling. The arrest warrant application identifies
          the firearms both as ‘‘AR-15 style semi-automatic .223 caliber assault rifle[s]’’
          and ‘‘AR-15 assault rifles.’’ During oral argument before this court, counsel
          for the defendant indicated that the defendant had conceded that the rifles
          at issue were ‘‘assault weapons’’ as that term is defined in General Statutes
          § 53-202a. Given that the statutory definition of ‘‘assault weapon’’ encompasses numerous specified semiautomatic firearms, including but not limited
          to the AR-15, counsel for the defendant also acknowledged that additional
          fact-finding may be necessary on remand to determine the specific type of
          rifles at issue for the purposes of applying Bruen.

       and Heller support the idea that, like firearms, not all
       firearm components are protected by the second
       amendment; rather, the right to keep and bear arms
       includes the right to keep and bear components that
       are necessary to effectively use those arms.
          Heller defined ‘‘arms’’ as ‘‘[w]eapons of offence’’ that
       can be used to ‘‘cast at or strike another.’’ (Internal
       quotation marks omitted.) District of Columbia v.
       
Heller, supra,
 
554 U.S. 581
. Some courts have concluded
       that certain firearm components are not ‘‘arms’’ because
       they do not independently meet that definition. See, e.g.,
       Firearms Regulatory Accountability Coalition, Inc. v.
       Garland, 
691 F. Supp. 3d 1043
, 1053 (D.N.D. 2023) (‘‘a
       stabilizing brace, like a silencer, cannot cause harm on
       its own and is not a bearable arm which would implicate
       [s]econd [a]mendment protections’’), rev’d on other

       arms’ protected by the [s]econd [a]mendment’’). Other
       courts, however, have applied a test that asks whether
       the firearm component is ‘‘necessary’’ or ‘‘essential’’ to
       operate a firearm as intended. See, e.g., United States

                In National Assn. for Gun Rights v. Lamont, supra, 
685 F. Supp. 3d 94

          magazine is ‘‘a modern instrument’’ that merely ‘‘facilitate[s] armed self-defense.’’ (Emphasis added; internal quotation marks omitted.); see also

597 U.S. 28
          (‘‘general definition [of ‘arms’] covers modern instruments that facilitate
          armed self-defense’’). We are not persuaded that this is the proper inquiry
          because ‘‘it would seemingly open the door to significantly broader [s]econd
          [a]mendment protections for firearm components’’; United States v. Berger,
          supra,

          than the court in Bruen likely intended by using that phrase in passing. See id.

          In Heller, the court held that the District of Columbia’s ‘‘requirement (as applied to [the] respondent’s
       handgun) that firearms in the home be rendered and
       kept inoperable at all times’’ was unconstitutional
       because it made ‘‘it impossible for citizens to use [those
       firearms] for the core lawful purpose of self-defense
       . . . .’’ District of Columbia v. 
Heller, supra,
 
554 U.S. 630
. In other words, Heller recognized that the right to
       keep and bear arms includes a right to use those arms
       and to keep them in operable condition ready for such
       use. See 
id.,
 617–18 (quoting T. Cooley, Treatise on
       Constitutional Limitations (1868) p. 271, as example of
       post-Civil War commentary interpreting second amendment right, for proposition that ‘‘to bear arms implies
       something more than the mere keeping; it implies the
       learning to handle and use them in a way that makes
       those who keep them ready for their efficient use’’
       (internal quotation marks omitted)). Similarly, in
       Bruen, the court confirmed that the ‘‘[s]econd [a]mendment protects the possession and use of weapons
       . . . .’’ (Emphasis added.) New York State Rifle & Pistol
       Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 21

       this right to use the guaranty would have hardly been
       worth the paper it consumed.’’ (Internal quotation

       609 (quoting J. Tiffany, A Treatise on the Unconstitutionality of American Slavery (1849) pp. 117–18, to illustrate founding era public understanding of second
       amendment right). It follows, therefore, that the second
       amendment, in addition to protecting arms in common
       use today for lawful purposes like self-defense, also
       must protect components that are necessary or essential to operate such an arm as intended. See United
       States v. Miller,

             Consequently, on remand, the defendant, as a predicate to his constitutional challenges to §§ 53a-211 and
          53-202w (c) (2), must prove that the silencers and large
          capacity magazines, even if they are not independently

;
          nonetheless fall within the term ‘‘arms’’ because they
          are necessary or essential to effectively operate a constitutionally protected firearm as intended. If the defendant fails to demonstrate that the silencers and large
          capacity magazines are necessary or essential to the
          effective use of a protected arm, the court’s analysis
          as to those instruments ends there and the defendant’s
          constitutional challenge fails. If those firearm components do meet that criterion, however, then the court,
          for the reasons set forth in part II A 2 of this opinion,
          must proceed to consider whether the defendant has
          shown that the silencers and large capacity magazines,
          as well as the AR-15 style rifles, are in common use
          within the meaning of Heller and Bruen.

             The defendant does not dispute that he has the burden of proving that his conduct is covered by the second
          amendment’s plain text. The parties do not agree, however, as to whether the defendant must show only that
          the firearms and firearm components at issue are
          ‘‘arms,’’ or whether he instead bears the additional burden of demonstrating that they are arms in common
          use or typically possessed for lawful purposes like self-defense. In other words, ‘‘[d]oes the challenging party
          have the burden at step one to show a regulated weapon

       Supreme Court, Docket No. S284349 (May 15, 2024).
       As the United States Court of Appeals for the Seventh
       Circuit has recognized, ‘‘[t]here is no consensus’’ among
       courts on this issue. Bevis v. Naperville, 
85 F.4th 1175, 1198

          In the present cases, the state, acknowledging that
       courts take different positions on whether the common
       use and dangerous and unusual analyses inform the
       threshold plain text inquiry or the historical inquiry
       under Bruen, addresses those issues at both steps of
       the analysis in its appellate brief. The defendant asserts,
       however, that he does not have a burden to show that
       the items at issue are commonly used for self-defense,
       typically possessed by law-abiding citizens, or not ‘‘dangerous and unusual.’’ According to the defendant, his
       burden at step one is merely to ‘‘assert that his conduct
       falls within the plain text of the second amendment,’’
       meaning, in the context of these cases, that the items
       at issue are ‘‘arms’’ or are ‘‘necessary’’ or ‘‘essential’’ to
       the functioning of a protected ‘‘arm.’’ He argues that,
       if he satisfies this threshold, the burden then shifts to
       the state to show that his conduct falls outside of the
       second amendment’s scope. At oral argument before
       this court, the defendant’s counsel further argued that
       the defendant has the burden at Bruen’s first step to
       prove in ‘‘the broadest sense’’ that the items at issue
       fall within the scope of the second amendment, and
       that the state has the burden to justify any exemptions
       to second amendment protection.28 For the following
          28
             The defendant’s counsel also suggested during oral argument before
       this court, however, that the defendant might have the burden of proving
       that the items are both commonly owned in the United States and ‘‘used in
       a lawful manner.’’

          reasons, we conclude that ‘‘common use,’’ along with
          the related ‘‘typical possession’’ and ‘‘dangerous and
          unusual’’ considerations, are part of Bruen’s first step,
          where the party challenging a firearm statute bears the
          burden of proof.
             One reason that courts frequently cite for placing the
          common use inquiry at step one is that the United States
          Supreme Court seemingly did so in Bruen. Specifically,
          the Supreme Court began its analysis in Bruen by stating: ‘‘It is undisputed that [the] petitioners . . . two
          ordinary, law-abiding, adult citizens—are part of ‘the
          people’ whom the [s]econd [a]mendment protects. . . .
          Nor does any party dispute that handguns are weapons
          ‘in common use’ today for self-defense. . . . We therefore turn to whether the plain text of the [s]econd
          [a]mendment protects [the petitioners’] proposed
          course of conduct—carrying handguns publicly for self-defense.’’ (Citations omitted; emphasis added.) New
          York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
          597 U.S. 31–32. Several courts view that language as a
          command from the Supreme Court to consider common
          use in relation to whether the second amendment protects the conduct at issue, rather than in relation to
          whether the regulation is consistent with this country’s
          history and tradition of firearms regulation. See, e.g.,
          United States v. Teston, Docket No. CR-22-1400 JB,
          
2024 WL 1621512
, *19, 21 (D.N.M. April 15, 2024) (‘‘most
          federal cases post-Bruen have taken this language as
          a command that [the] ‘in common use’ analysis should
          be undertaken as part of a court’s step-one, plain-text
          analysis under Bruen,’’ and District Court would ‘‘not
          presume that the Supreme Court’s approach to the
          Bruen analysis . . . [was] careless or casual’’).29 Given

       that Bruen also referenced the popularity of handguns
       for self-defense in relation to the second step of its
       analysis, however, the court’s passing reference to
       ‘‘ ‘common use’ ’’ in relation to the plain text inquiry is
       not dispositive. New York State Rifle & Pistol Assn.,

       in the 1690s . . . provide no justification for laws
       restricting the public carry of weapons that are unquestionably in common use today’’) (internal quotation
       marks omitted)).

          Nevertheless, in Heller, the Supreme Court used the
       phrase ‘‘in common use at the time’’ to define ‘‘the
       sorts of weapons protected’’ by the second amendment.
       (Internal quotation marks omitted.) District of Columbia v. 
Heller, supra,

. Indeed, in both Heller
       and Bruen, the court explained that not all ‘‘[w]eapons
       of offence’’ that can be used ‘‘to cast at or strike
       another’’; (internal quotation marks omitted) 
id., 581
;
       constitute protected ‘‘arms.’’ Although the court in
       Heller initially stated that ‘‘the [s]econd [a]mendment
       extends, prima facie, to all instruments that constitute
       bearable arms’’; (emphasis added)

       whether handguns were arms that were in common use today for self-defense and whether the plain text of the [s]econd [a]mendment covered

          proposition that the [s]econd [a]mendment right, whatever its nature, extends only to certain types of weapons.’’ (Emphasis added.) District of Columbia v. 
Heller, supra, 623
. In Miller, the Supreme Court upheld a federal prohibition on transporting an unregistered, short-barreled shotgun in interstate commerce, reasoning
          that, ‘‘[i]n the absence of any evidence tending to show
          that possession or use of a shotgun having a barrel of
          less than eighteen inches in length at this time has some
          reasonable relationship to the preservation or efficiency
          of a well regulated militia, we cannot say that the [s]econd [a]mendment guarantees the right to keep and bear
          such an instrument. Certainly, it is not within judicial
          notice that this weapon is any part of the ordinary
          military equipment or that its use could contribute to the
          common defense.’’ (Internal quotation marks omitted.)
          United States v. 
Miller, supra, 175, 178
.
             In Heller, the court rejected Justice Stevens’ argument in his dissenting opinion that Miller’s ‘‘ ‘ordinary
          military equipment’ ’’ language meant that ‘‘only those
          weapons useful in warfare are protected. That would
          be a startling reading of the opinion, since it would mean
          that . . . restrictions on machineguns . . . might be
          unconstitutional, machineguns being useful in warfare
          in 1939.’’ District of Columbia v. 
Heller, supra,
 
554 U.S. 624
. Instead, the court stated that ‘‘Miller’s ordinary
          military equipment language must be read in tandem
          with what comes after: [O]rdinarily when called for
          [militia] service [able-bodied] men were expected to
          appear bearing arms supplied by themselves and of the

          militia was formed from a pool of men bringing arms
          in common use at the time for lawful purposes like
          self-defense. In the colonial and revolutionary war era,
          [small-arms] weapons used by militiamen and weapons
          used in defense of person and home were one and the
          same. . . . We therefore read Miller to say only that

                                    State v. Giannone

       the [s]econd [a]mendment does not protect those weapons not typically possessed by law-abiding citizens
       for lawful purposes, such as short-barreled shotguns.

       scope of the right . . . .’’ (Citations omitted; emphasis

Id.,

       In other words, the court concluded that, under Miller,
       the second amendment protects ‘‘the sorts of weapons
       . . . in common use at the time’’ and explained that
       this is an ‘‘important limitation on the right to keep and
       carry arms . . . that . . . is fairly supported by the
       historical tradition of prohibiting the carrying of dangerous and unusual weapons.’’ (Citation omitted; internal
       quotation marks omitted.) 
Id., 627
. In Bruen, the court
       reiterated Heller’s point that ‘‘the [s]econd [a]mendment protects the possession and use of weapons that

       marks omitted.) New York State Rifle & Pistol Assn.,
       Inc. v. 
Bruen, supra,
 
597 U.S. 21
.
          Further, the court in Heller strongly suggested, consistent with the common use limitation, that weapons
       that are ‘‘most useful in military service—M-16 rifles30
       and the like—may be banned’’; (footnote added) District of Columbia v. 
Heller, supra,

          court reiterated, ‘‘the conception of the militia at the
          time of the [s]econd [a]mendment’s ratification was the
          body of all citizens capable of military service, who
          would bring the sorts of lawful weapons that they possessed at home to militia duty.’’ (Emphasis added.) 
Id.
          Although recognizing that, today, ‘‘a militia, to be as
          effective as militias in the 18th century, [may] require
          sophisticated arms that are highly unusual in society
          at large,’’ the court declined to alter its interpretation
          of the second amendment right to account for ‘‘modern
          developments [that] have limited the degree of fit
          between the prefatory clause and the protected right
          . . . .’’ 
Id.,
 627–28.
            Consequently, the common use analysis informs
          whether the conduct at issue is covered by the second
          amendment’s plain text and asks whether an instrument, even if it is an ‘‘arm,’’ is the type of arm that is
          protected by the second amendment—that is, as Bruen
          and Heller instruct, an arm that is commonly used or
          typically possessed for lawful purposes like self-defense—or is instead a dangerous and unusual weapon
          that falls outside of the second amendment’s scope.
          See New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 21
; District of Columbia v. 
Heller, supra,
          554 U.S. 624–27. In other words, because Bruen’s
          threshold inquiry as to whether the plain text protects
          the conduct at issue necessarily requires courts to interpret the meaning of ‘‘arms’’ in the second amendment,
          and because Bruen and Heller make clear that the second amendment protects arms ‘‘in common use at the
          time’’; (internal quotation marks omitted) New York

;

       2024) (No. 24-4083).31

          Our conclusion finds further support in Heller’s
       apparent exclusion of machine guns and short-barreled
       shotguns from the class of constitutionally protected
       arms. In stating that it would be ‘‘startling’’ if Miller
       stood for the proposition that ‘‘only those weapons
       useful in warfare are protected . . . since it would
       mean that . . . restrictions on machineguns . . .
       might be unconstitutional, machineguns being useful
       in warfare in 1939,’’ the court suggested that restrictions
       on machine guns are constitutional. District of Columbia v. 
Heller, supra,
 
554 U.S. 624

       explained, ‘‘Miller’s ordinary military equipment language must be read in tandem with what comes after:

          quotation marks omitted.) 
Id.,
 624–25. The court thus
          suggested that certain weapons, such as machine guns
          and short-barreled shotguns, are categorically excluded
          from the second amendment right and that the state
          therefore may regulate such weapons, solely on the
          ground that they are not in common use or are not
          typically possessed by law-abiding citizens for lawful
          purposes, rather than on the ground that there are relevantly similar historical analogues restricting the possession of those weapons. Such reasoning supports our
          conclusion that the common use analysis informs the
          scope of the second amendment right.
            Moreover, our conclusion is consistent with that of
          a majority of other courts that have decided the issue.32

             At least one court, however, has concluded that the issue of whether a
          weapon is in common use or is dangerous and unusual is properly considered
          at step two, at which the state bears the burden of proof. See Teter v. Lopez,
          
76 F.4th 938

          of a weapon’s dangerous and unusual character lies in the historical tradition
          of prohibiting the carrying of dangerous and unusual weapons. . . . It did
          not say that dangerous and unusual weapons are not arms. Thus, whether
          butterfly knives are dangerous and unusual is a contention as to which
          Hawaii bears the burden of proof in the second prong of the Bruen analysis.’’

                                     State v. Giannone

       Although not all of those courts decided which party
       bears the burden of proof on the common use issue,33
       a majority of courts that have considered common use
       at the first step have placed the burden of proof on that
       issue on the party challenging the statute at issue.34
          It may be argued that Bruen’s first step is purely a
       textual inquiry and that the common use limitation,
       which is drawn from history and is not expressly contained in the amendment’s plain text, has no place in
       that inquiry but, rather, is properly addressed as part
       of Bruen’s second step.35 For instance, in a dissenting
          Other courts have declined to decide the issue of the placement of the
       ‘‘common use’’ inquiry altogether. For instance, in Bevis, the Seventh Circuit
       defined the step one inquiry as whether the weapons at issue are ‘‘[a]rms
       that individual persons are entitled to keep and bear,’’ which, it concluded,
       ‘‘extend[ed] only to weapons in common use for a lawful purpose.’’ (Internal
       quotation marks omitted.) Bevis v. 
Naperville, supra,
 
85 F.4th 1192
, 1193.
       After resolving the appeal at step one of the analysis, however, the court,
       turning to the second step ‘‘for the sake of completeness,’’ acknowledged
       the lack of consensus on the placement of the ‘‘common use’’ factor and,
       despite its initial placement of that factor at the first step, ‘‘assume[d]
       (without deciding the question) that this is a step two inquiry, where the
       state bears the burden of proof.’’

          opinion in Bevis v. 
Naperville, supra,
 
85 F.4th 1175
,
          Circuit Judge Brennan asserted that common use is
          properly considered at step two because ‘‘the broader
          definition of [a]rms . . . should be read as [a]rms—
          not [a]rms in common use at the time. . . . The
          [Supreme] Court did not say that dangerous and unusual
          weapons are not arms. . . . [I]mporting the phrase in
          common use to assess whether firearms are [a]rms . . .
          improperly restricts the constitutional right. . . . [I]n
          common use is a sufficient condition for finding arms
          protected under the history and tradition test in Bruen,
          not a necessary condition to find them [a]rms.’’ (Citations omitted; emphasis in original; internal quotation
          marks omitted.) 
Id., 1209
 (Brennan, J., dissenting).
          Judge Brennan further reasoned that the common use
          limitation is drawn ‘‘not . . . from a historical understanding of what an [a]rm is’’ but instead from ‘‘the
          historical tradition of prohibiting the carrying of dangerous and unusual weapons.’’ (Internal quotation marks
          omitted.) 
Id.
             We acknowledge that there is a logical argument to
          be made that the common use limitation is part of the
          state’s burden at step two. Until the United States
          Supreme Court clarifies the Bruen test, however, our
          responsibility as a lower court is to apply the Supreme
          Court’s precedent as we are best able to understand it.
          Our reading of that precedent dictates that the second
          amendment’s ‘‘plain text’’ must not be considered in a
          vacuum. As the Supreme Court stated in Bruen, ‘‘the
          [s]econd [a]mendment’s definition of ‘arms’ is fixed
          according to its historical understanding . . . .’’ New
          York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
          
597 U.S. 28
. This is consistent with the idea ‘‘that the
          [s]econd [a]mendment . . . codified a pre-existing
          right’’ and that its ‘‘very text . . . implicitly recognizes
          common use’ question is, itself, rooted in historical inquiry—which makes
          step two of the Bruen analysis a better fit for its consideration’’).

 (‘‘the [s]econd [a]mendment was not intended
       to lay down a novel principl[e] but rather codified a
       right inherited from our English ancestors’’ or, in other
       words, ‘‘codified venerable, widely understood liberties’’ (internal quotation marks omitted)). Consequently, the second amendment is ‘‘enshrined with the
       scope [it was] understood to have when the people
       adopted [it].’’ (Internal quotation marks omitted.) New
       York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra, 34
; District of Columbia v. 
Heller, supra,
 634–35. Therefore, although history has a principal role in Bruen’s
       second step, the Supreme Court instructs that ‘‘the historical understanding of the scope of the right’’; District
       of Columbia v. 
Heller, supra, 625
; also informs the
       meaning of the second amendment’s text. That historical understanding, as the Supreme Court explained,
       was that the right was not an unlimited one ‘‘to keep
       and carry any weapon whatsoever in any manner whatsoever and for whatever purpose’’; New York State
       Rifle & Pistol Assn., Inc. v. 
Bruen, supra, 21
; but, rather,
       that ‘‘the sorts of weapons protected were those in
       common use at the time’’; 
id., 81
 (Kavanaugh, J., concurring); and not those that were ‘‘dangerous and unusual’’;
       (internal quotation marks omitted) 
id., 21
; nor those
       ‘‘not typically possessed by law-abiding citizens for lawful purposes, such as short-barreled shotguns.’’ District
       of Columbia v. 
Heller, supra, 625
.
          Last, we also conclude that the common use analysis
       at Bruen’s first step incorporates both the ‘‘typical possession’’ and ‘‘dangerous and unusual’’ considerations.
       In Heller, the court used those three phrases together
       to define the limits on the types of ‘‘arms’’ to which the
       second amendment extends. See 
id.,
 624–27. Specifically, the court equated ‘‘in common use’’ with ‘‘typically
Page 46                         CONNECTICUT LAW JOURNAL                                      0, 0

          possessed’’ when it interpreted Miller’s discussion of
          the types of weapons that citizens were historically
          expected to bear when they appeared for militia service—namely, those ‘‘of the kind in common use at the
          time’’—as saying ‘‘only that the [s]econd [a]mendment
          does not protect those weapons not typically possessed
          by law-abiding citizens for lawful purposes . . . .’’
          (Internal quotation marks omitted.) 
Id.,
 624–25. The
          court confirmed that its interpretation of Miller was in
          ‘‘[accord] with the historical understanding of the scope
          of the right,’’ which was that it ‘‘was not a right to
          keep and carry any weapon whatsoever in any manner
          whatsoever and for whatever purpose’’ but, rather, was
          limited to weapons ‘‘in common use at the time,’’ which,
          in turn, the court found ‘‘fairly supported by the historical tradition of prohibiting the carrying of dangerous
          and unusual weapons.’’ (Internal quotation marks omitted.) 
Id.,
 626–27. Further, in its summary of that language in Bruen, the court juxtaposed weapons ‘‘in common use at the time’’ with ‘‘dangerous and unusual’’
          weapons, suggesting that those phrases are opposite
          sides of the same coin: ‘‘[T]he [s]econd [a]mendment
          protects only the carrying of weapons that are those
          in common use at the time, as opposed to those that
          are highly unusual in society at large. . . . Whatever
          the likelihood that handguns were considered dangerous and unusual during the colonial period, they are
          indisputably in common use for self-defense today.’’

          New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 47
. Thus, Bruen and Heller suggest that
          the ‘‘common use,’’ ‘‘typical possession,’’ and ‘‘dangerous and unusual’’ issues are inextricably intertwined
          when assessing whether a weapon is protected under
          the second amendment.36 For that reason, we view all
            36
               We acknowledge that Heller and Bruen do not explicitly state that the
          second amendment does not protect dangerous and unusual weapons but,
          rather, recognize only that there is a ‘‘historical tradition of prohibiting the
          carrying’’ of such weapons. New York State Rifle & Pistol Assn., Inc. v.
0, 0                         CONNECTICUT LAW JOURNAL                                      Page 47

                                     State v. Giannone

       three of those phrases as bearing upon the common use
       inquiry at Bruen’s first step. Indeed, the considerations
       that other courts find relevant to whether a weapon is
       in common use often overlap with those that courts
       find relevant to whether a weapon is typically possessed
       by law-abiding citizens for lawful purposes or is dangerous and unusual. See, e.g., National Assn. for Gun
       Rights v. Lamont, supra, 
685 F. Supp. 3d 85
, 87 (‘‘court
       [read] Bruen to abrogate Cuomo to the extent it treated
       common use’’ and ‘‘typical possession’’ as distinct
       inquiries, and noting that ‘‘there is a degree of overlap
       between the analyses for ‘common use,’ ‘typical possession,’ and ‘dangerous and unusual’ in the context of the
       [s]econd [a]mendment’’)).37
         Therefore, we conclude that, on remand, the defendant bears the burden in the first instance to establish
       
Bruen, supra,
 
597 U.S. 21
; District of Columbia v. 
Heller, supra,
 
554 U.S. 627
. The Supreme Court, however, references that historical tradition only
       in an effort to define the types of weapons to which the second amendment
       extends. See New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra, 21
;
       District of Columbia v. 
Heller, supra, 625
. Accordingly, since before Bruen,
       courts, including our Supreme Court, have interpreted the ‘‘dangerous and
       unusual’’ language in Heller as creating an exception to second amendment
       protection for dangerous and unusual weapons. See State v. DeCiccio, supra,
       
315 Conn. 110

          that the items at issue are arms in common use or
          typically possessed for lawful purposes like self-defense
          and, by implication, are not dangerous and unusual
          weapons. If he satisfies that burden, the state can then
          present evidence that the weapons are not, in fact, in
          common use or typically possessed for lawful purposes
          like self-defense, or are dangerous and unusual, and
          thus fall outside of the second amendment’s scope. To
          be clear, the initial burden is on the party challenging
          the statute at issue to demonstrate that the second
          amendment presumptively protects the regulated
          weapon, and not on the state to prove that the weapon
          is not protected. In weighing the evidence presented
          by the parties, the court must decide whether the defendant has proved by a preponderance of evidence that
          the item at issue is (1) in fact an ‘‘arm’’ or an accessory
          that is necessary or essential to render a protected arm
          operable and (2) in common use or typically possessed
          for lawful purposes like self-defense.
                                              3
             Having concluded that the defendant bears the burden of proof on the common use issue, we now turn
          to what that inquiry might entail. The defendant argues
          that the relevant inquiry is only whether the arm is
          ‘‘typically possessed for lawful purposes,’’ rather than
          whether it is commonly used—i.e., fired—for a lawful
          purpose. In other words, the defendant asserts that he
          can satisfy his burden simply by presenting statistical
          evidence that the firearms and firearm components at
          issue are commonly owned in this country. The defendant’s counsel suggested at oral argument before this
          court, however, that the defendant may have to show
          that those items, in addition to being commonly owned,
          are ‘‘used in a lawful manner.’’ Although, in his principal
          of Safety & Homeland Security,

                                    State v. Giannone

       appellate brief, the defendant does not clearly define
       the ‘‘lawful purpose’’ for which he asserts AR-15 style
       rifles and large capacity magazines are commonly used
       or owned,38 he argues in his reply brief that those items
       are commonly used for self-defense. The defendant also
       asserts for the first time in his reply brief that ‘‘[h]unting
       rifles with semiautomatic action are ubiquitous,’’ suggesting that hunting may be another lawful purpose for
       which semiautomatic rifles like an AR-15 style rifle are
       commonly used. As to silencers, the defendant argues
       that they ‘‘have legitimate uses in hunting, target shooting, and self-defense’’ because they protect the user’s
       hearing. The defendant further argues, emphasizing the
       ‘‘conjunctive’’ nature of the ‘‘dangerous and unusual’’
       inquiry, that a weapon cannot be considered ‘‘dangerous and unusual,’’ and therefore outside of the second
       amendment’s scope, if it is commonly owned. He also
       suggests, however, that it may be relevant to whether
       a weapon is dangerous and unusual to consider its
       ‘‘inherent risk’’ and use in crime.
          The state asserts, on the other hand, that we should
       adopt the formulation of the common use inquiry
       applied in National Assn. for Gun Rights v. Lamont,
       supra, 
685 F. Supp. 3d 63
. In that case, the court asked
       whether the weapon at issue was commonly used for
       self-defense and typically possessed for that purpose
       or, instead, was dangerous or unusual, meaning that
       the weapon was used in a way that made it particularly
       dangerous or it was unusual for the weapon to be possessed for self-defense. See id., 90–91. Thus, according
       to the state, a weapon is protected by the second amendment only if it is both commonly used and typically
          38
             For instance, the defendant asserts generally that both large capacity
       magazines and ‘‘[t]he semiautomatic rifles Connecticut defines as assault
       weapons are typically possessed by law-abiding citizens for lawful purposes
       . . . .’’ He also notes in passing that, although ‘‘[a] self-defense situation
       is . . . rare,’’ large capacity magazines ‘‘are used for lawful self-defense
       purposes.’’

          possessed for self-defense and is therefore neither

             Initially, we seek to clarify the ‘‘lawful purpose’’ for
          which the items at issue must be ‘‘in common use.’’ In
          Heller, the Supreme Court emphasized that individual
          self-defense is the ‘‘core lawful purpose’’ protected by
          the second amendment; District of Columbia v. 
Heller, supra,
 
554 U.S. 630
; as well as ‘‘the central component’’
          of the second amendment right; (emphasis in original)
          
id., 599
; a point that the court later reiterated in New
          York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
          
597 U.S. 29
. Nevertheless, the Supreme Court also stated
          in Heller that the second amendment protects weapons
          that are ‘‘typically possessed by law-abiding citizens
          for lawful purposes’’ generally. District of Columbia v.
          
Heller, supra, 625
.39 Thus, we conclude that self-defense,
          although the core lawful purpose protected by the second amendment, is not necessarily the only lawful purpose that receives such protection.40
            39
                 Although Bruen focuses on self-defense and does not use the same
          ‘‘lawful purposes’’ language as Heller; see New York State Rifle & Pistol
          Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 32
, 47 (undisputed that handguns were
          in common use for self-defense); we do not view Bruen as holding that self-defense is the sole lawful purpose protected by the second amendment. In
          Bruen, the court had no reason to discuss other lawful purposes because
          the parties argued that their proposed conduct involved self-defense. 
Id., 32
. Moreover, the absence of such discussion from the court’s opinion does
          not mean that Heller’s ‘‘lawful purposes’’ language is no longer relevant.
          Indeed, in Bruen, the court indicated that it was clarifying and applying
          Heller, not overruling it. See New York State Rifle & Pistol Assn., Inc. v.
          
Bruen, supra, 31
 (‘‘[h]aving made the constitutional standard endorsed in
          Heller more explicit, we now apply that standard to New York’s proper-cause requirement’’).

                 But see, e.g., Bevis v. 
Naperville, supra,
 
85 F.4th 1192
 (‘‘Both Supreme
          Court decisions and historical sources indicate that the [a]rms the [s]econd
          [a]mendment is talking about are weapons in common use for self-defense.
          That is not to say that there are no other lawful uses for weapons—sporting
          uses, collection, and competitions come to mind as examples. But the constitutional protection exists to protect the individual right to self-defense, and
          so that will be our focus.’’); Oregon Firearms Federation v. Kotek, supra,

           Hunting and target shooting, the additional lawful
       purposes suggested by the defendant, might qualify as
       other protected lawful purposes. Indeed, the Supreme
       Court explained that ‘‘[t]he prefatory clause does not
       suggest that preserving the militia was the only reason
       Americans valued the ancient right; most undoubtedly
       thought it even more important for self-defense and
       hunting.’’ (Emphasis added.) Id., 599; see also Heller

       self-defense is second amendment’s ‘‘central component’’ as recognizing that ‘‘the [s]econd [a]mendment

       omitted)). Furthermore, that target shooting for the
       purpose of training also may be a protected lawful purpose finds support in the court’s conclusion that ‘‘the

          20, 2024) (No. 24-178).41 At least one court, however,
          has called into question whether hunting and other recreational uses of arms are protected by the second
          amendment. See, e.g., Oregon Firearms Federation v.
          Kotek, supra, 
682 F. Supp. 3d 917
 (‘‘[h]unting and other
          recreational uses of guns have no explicit or otherwise
          direct protection in the text of the [c]onstitution or
          under existing doctrine, nor does the historical evidence support such a conclusion’’ (internal quotation
          marks omitted)). In the present cases, neither party has
          fully addressed, either before the trial court or this
          court, what lawful purposes are protected by the second
          amendment. Thus, to the extent that the defendant
          seeks to argue on remand that AR-15 style rifles, large
          capacity magazines, and silencers are in common use
          for a lawful purpose other than self-defense, we leave
          it to the trial court to decide, on the basis of the record
          developed by the parties, whether the proposed lawful
          purpose is one protected by the second amendment.

            We now consider how the trial court is to assess
          whether a weapon is in common use today for lawful
          purposes. Although the Supreme Court made clear in
          Bruen that ‘‘the [s]econd [a]mendment protects the possession and use of weapons that are in common use at

; it did not set forth any sort of analytical framework for evaluating whether a weapon satisfies that
          criteria. Because it was undisputed in Bruen ‘‘that handguns are weapons in common use today for self-defense,’’ it was unnecessary for the court to analyze
          the issue. (Internal quotation marks omitted.)

       have considered when assessing whether a weapon is
       commonly used or typically possessed today for lawful
       purposes or whether the weapon is, by contrast, dangerous and unusual. We do not endeavor to define precisely
       all of the evidence that the court should consider or
       how it should weigh such evidence; rather, we simply
       observe that there are several considerations that may
       inform a court’s analysis of those issues.42

         First, to address the defendant’s argument on statistical numerosity, by contrasting weapons ‘‘in common
       semiautomatic rifles)] for lawful purposes like self-defense, hunting, and
       target shooting’’).
          42
             Given our conclusion that the ‘‘dangerous and unusual’’ issue is encompassed within the ‘‘common use’’ inquiry rather than is itself a distinct
       inquiry, we do not find it necessary to separately define ‘‘dangerous and
       unusual.’’ We do find it necessary, however, to address the state’s argument
       that the proper formulation of the phrase is ‘‘dangerous or unusual.’’ The
       state relies on National Assn. for Gun Rights v. Lamont, supra, 
685 F. Supp. 3d 90
, in which the court rejected that ‘‘dangerous and unusual’’ was
       a conjunctive test because ‘‘Heller’s use of [that] phrase . . . does not state
       that it must be conjunctive, but instead cites to several sources . . . [that]
       use the phrase ‘dangerous or unusual weapons’ . . . .’’ (Citations omitted;
       emphasis omitted.) We are not persuaded.
          In Bruen, the Supreme Court carefully used the phrase ‘‘dangerous and
       unusual’’ five times to describe the tradition of prohibiting the carrying of
       dangerous and unusual weapons, and it used the phrase ‘‘dangerous or
       unusual’’ only once when quoting from the brief submitted by the government’s amici. New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 21
, 46–47, 51; see also Caetano v. Massachusetts, 
577 U.S. 411
, 417–18,
       
136 S. Ct. 1027
, 
194 L. Ed. 2d 99
 (2016) (Alito, J., concurring in the judgment)
       (Whether a weapon is dangerous and unusual ‘‘is a conjunctive test: A
       weapon may not be banned unless it is both dangerous and unusual. . . .
       [T]he relative dangerousness of a weapon is irrelevant when the weapon
       belongs to a class of arms commonly used for lawful purposes. . . . If
       Heller tells us anything, it is that firearms cannot be categorically prohibited
       just because they are dangerous.’’ (Citations omitted; emphasis omitted;
       internal quotation marks omitted.)). Thus, the Supreme Court has made it
       fairly clear that a weapon does not fall outside of the second amendment’s
       scope merely because it is relatively dangerous. We reiterate that the ‘‘common use’’ inquiry asks whether the weapons are commonly used or typically
       possessed for lawful purposes like self-defense. Accordingly, to the extent
       that the state seeks to demonstrate on remand that the weapons at issue
       are dangerous, evidence of the weapon’s dangerousness informs the ‘‘common use’’ inquiry only insofar as it tends to show that the weapon is not in
       fact commonly used or owned by American citizens for such lawful purposes.

          that the plaintiff had proved that AR-15s were in common use for lawful purposes, relied on evidence that
          ‘‘AR-15 firearms are produced by a multitude of manufacturers and are commonly owned throughout the
          United States—it is estimated that as of 2022, AR-15s
          and similar sporting rifles had around 24 million owners; this ownership number was exceeded only by the
          number of registered handgun owners within our

              We note that, although our proposed analysis is similar, we do not adopt
       the same analytical framework that the court applied in National Assn. for

       certain aspects of the court’s analysis in that case but remain unconvinced
       by others. In particular, we do not agree that ‘‘a weapon must be both
       possessed for the purpose of and actually used for self-defense in order to
       fall within the [s]econd [a]mendment’s protection . . . .’’ (Emphasis added.)
       Id., 90–91. As discussed further in this opinion, although how a weapon is
       used is relevant to the analysis, we do not believe that it is necessary that

 (common use is not dispositive of inquiry but must
          be considered in conjunction with how firearm or firearm accessory is used).
            Several considerations may inform a court’s inquiry
          into how and why a weapon is used. For example, a
          court may find it relevant to assess how frequently the
          weapon is in fact used for lawful purposes like self-defense. See, e.g., Hanson v. District of Columbia, 
671 F. Supp. 3d 1
, 14, 16 (D.D.C. 2023) (magazines with
          capacity of more than ten rounds are ‘‘not in fact commonly used for self-defense’’ because civilians fire average of 2.2 shots in self-defense incidents), appeal filed
          (D.C. Cir. May 17, 2023) (No. 23-7061). A court may
          weigh that evidence against other evidence tending to
          show that the weapon is instead disproportionately
          used for unlawful purposes. See, e.g., National Assn.
          for Gun Rights v. Lamont, supra, 
685 F. Supp. 3d 99
          (although ‘‘mindful of the fact that the commonality of
          a particular firearm or weapon’s use in crime was not
          enough to find in either Heller or Cuomo that the firearms at issue were not typically used for law-abiding
          purposes,’’ and thus not treating such evidence as dispositive, court found that evidence as to suitability of
          assault weapons for crime outweighed limited evidence
          presented on their use for self-defense); Oregon Firearms Federation, Inc. v. Brown, 
644 F. Supp. 3d 782
,
          801 (D. Or. 2022) (large capacity magazines are not
          in common use for lawful purposes like self-defense

2022 WL 18956023

           Additionally, a court may find it relevant to consider
          whether the firearm is predominantly used by the milia weapon is frequently fired or deployed to receive second amendment
          protection.

          States Supreme Court has deemed ‘‘the quintessential
          self-defense weapon.’’ District of Columbia v. Heller,
          supra, 
554 U.S. 629
. For example, in Bevis v. 
Naperville, supra,
 
85 F.4th 1197
, the Seventh Circuit focused its
          inquiry at Bruen’s first step regarding whether the
          weapons at issue ‘‘[fell] on the military or civilian side
          of the line.’’ The court explained that ‘‘what distinguishes AR-15s from M-16s . . . is important precisely
          because Heller itself stated that [M-16s] are not among
          the [a]rms covered by the [s]econd [a]mendment; they
          are instead a military weapon.’’ 
Id., 1195
. On the basis
          of the limited evidence presented during proceedings
          on the plaintiffs’ motion for a preliminary injunction,
          the court in Bevis concluded that AR-15s and large
          capacity magazines ‘‘are much more like machineguns
          and military-grade weaponry than they are like the many
          different types of firearms that are used for individual
          self-defense (or so the legislature was entitled to conclude). Indeed, the AR-15 is almost the same gun as the
          [M-16] . . . . The only meaningful distinction (unless
          the user takes advantage of some simple modifications
          that essentially make it fully automatic) is that the AR-
          15 has only semiautomatic capability . . . while the
          [M-16] operates both ways. Both weapons share the
          same core design, and both rely on the same patented
          operating system.’’ (Footnote omitted.) 
Id.,
 1195–96; see
          also footnote 30 of this opinion. The court also compared the firing rates of the AR-15 and M-16 but noted
          that ‘‘[b]etter data on firing rates might change the analysis . . . .’’ Bevis v. 
Naperville, supra, 1197
. Given that
          ‘‘this [was] just a preliminary look at the subject,’’ however, the court did ‘‘not rule out the possibility that
          used for individual self-defense (or so the legislature was entitled to conclude)’’); see also State v. DeCiccio, supra, 
315 Conn. 122
, 133 (in assessing
          whether dirk knives and police batons are ‘‘dangerous and unusual weapons,’’ court relied on, inter alia, findings that police batons and dirk knives
          were ‘‘inherently less lethal’’ or had ‘‘more limited lethality relative’’ to
          handguns).

       the plaintiffs [would] find other evidence that shows a
       sharper distinction between AR-15s and [M-16s] . . .
       than the . . . record reveal[ed].’’ Id.
         The defendant rejects, as unsupported by Bruen,
       McDonald, or Heller, the line that the court in Bevis
       drew between military and civilian weapons. We do not
       agree that such a distinction has no basis in the Supreme
       Court’s precedent. Assessing a firearm’s militaristic
       character as part of the common use inquiry finds support in Heller’s indication that weapons that are ‘‘most
       useful in military service—M-16 rifles and the like’’—
       are not the types of weapons typically possessed by
       law-abiding citizens for lawful purposes. District of
       Columbia v. Heller, supra, 
554 U.S. 627
. Similar to the
       court in Bevis, we view Heller’s recognition of the handgun as ‘‘the quintessential self-defense weapon’’; id.,
       629; and suggestion that military grade weapons like
       M-16s are not protected arms; see id., 624–25, 627; as
       establishing two ‘‘arms’’ at opposite ends of a spectrum.
       As the court in Bevis explained, determining ‘‘the types
       of ‘[a]rms’ that are covered by the [s]econd [a]mendment . . . presents a line-drawing problem. Everyone
       can agree that a personal handgun, used for self-defense, is one of those [a]rms that law-abiding citizens
       must be free to ‘keep and bear.’ Everyone can also
       agree, we hope, that a nuclear weapon such as the nowretired M388 Davy Crockett system, with its 51-pound
       W54 warhead, can be reserved for the military . . . .
       Many weapons, however, lie between these extremes.’’
       (Footnotes omitted.) Bevis v. 
Naperville, supra,
 85
       F.4th 1182–83. The common use inquiry aims to determine exactly where the weapons at issue fall on that
       spectrum.
         The defendant also argues that common use does not
       require ‘‘the actual firing of a weapon’’ because, if it
       did, ‘‘the Heller court would have looked at statistical
Page 60                   CONNECTICUT LAW JOURNAL                       0, 0

          averages about how often handguns were fired for self-defense. The statistic was never mentioned.’’ (Internal
          quotation marks omitted.) In support of this position,
          the defendant cites two pre-Bruen cases that applied
          Heller. See footnote 8 of this opinion. First, the defendant cites Justice Alito’s concurring opinion in Caetano
          v. Massachusetts, 
577 U.S. 411
, 
136 S. Ct. 1027
, 
194 L. Ed. 2d 99
 (2016), in which the United States Supreme
          Court vacated the lower court’s judgment and
          remanded the case to that court because it had failed to
          properly apply Heller to a challenge to a Massachusetts
          prohibition on the possession of stun guns. The defendant asserts that, in considering ‘‘whether stun guns
          are commonly possessed by law-abiding citizens for
          lawful purposes today’’; (emphasis omitted) 
id., 420
          (Alito, J., concurring in the judgment); Justice Alito
          considered only the number of Tasers and stun guns
          that were sold to private citizens, not how often those
          weapons were used. 
Id.
 Second, the defendant asserts
          that, in State v. DeCiccio, supra, 
315 Conn. 108
, in which
          our Supreme Court considered whether dirk knives and
          police batons are ‘‘arms’’ for purposes of the second
          amendment, the court did not ‘‘consider how often
          [those weapons] were used for self-defense . . . .
          Instead, it concluded that both are typically possessed
          by law-abiding citizens for lawful purposes.’’
             We agree with the defendant that a firearm does not
          have to be fired regularly to constitute a weapon in
          common use for lawful purposes like self-defense. As
          the defendant argues, a firearm can be ‘‘ ‘used’ ’’ for
          self-defense even if it is never actually fired. See, e.g.,
          Duncan v. 
Bonta, supra,
 
695 F. Supp. 3d 1227
 (‘‘[A]
          firearm kept on one’s nightstand is used for self-defense
          even when the night is quiet. It is kept and used in case
          of confrontation. A person may happily live a lifetime
          without needing to fire their gun in self-defense. But
          that is not to say that such a person does not use their

       gun for self-defense when he or she keeps it under the
       bed with a hope and a prayer that it never has to be

682 F. Supp. 3d 921
 (‘‘[A]n individual need not fire a gun to use it for self-defense. . . .
       [I]n brandishing a firearm to intimidate an attacker,
       for instance, the individual uses the firearm for self-defense.’’ (Footnote omitted.)). To be sure, the Supreme
       Court focused on the handgun being ‘‘the most popular
       weapon chosen by Americans for self-defense in the
       home,’’ rather than whether it was in fact commonly
       deployed for that lawful purpose. (Emphasis added;
       internal quotation marks omitted.) New York State
       Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 22
;
       see also District of Columbia v. Heller, supra, 
554 U.S. 629
 (same). Moreover, in Heller, the court did not limit
       the second amendment right to only ‘‘using’’ or ‘‘carrying’’ weapons but, instead, stated that the ordinary
       meaning of the phrase ‘‘keep [a]rms’’ in the second
       amendment is ‘‘have weapons.’’ (Internal quotation
       marks omitted.) District of Columbia v. Heller, supra,
       582; id., 583 (‘‘ ‘[k]eep arms’ was simply a common way
       of referring to possessing arms, for militiamen and
       everyone else’’ (emphasis omitted)). Accordingly, we
       do not view the common use limitation as requiring the
       actual use of a weapon. Therefore, a court may find it
       relevant to Bruen’s threshold inquiry to consider, in
       addition to or in place of evidence of how frequently
       a firearm is actually fired, evidence that demonstrates
       that a weapon is typically possessed or owned for lawful
       purposes, including, but not limited to, gun owners’
       subjective reasons for owning the firearm at issue in
       conjunction with rates of gun ownership.49

             Nonetheless, neither Justice Alito’s concurring opinion in Caetano, aside from the fact that it is not binding
          on this court, nor our Supreme Court’s decision in
          DeCiccio suggest that how frequently a weapon is actually deployed for lawful purposes is irrelevant to the
          common use inquiry. Indeed, just as evidence that a
          weapon is commonly owned or kept in the home for
          the purpose of self-defense may inform a court’s assessment of whether Americans commonly choose a given
          weapon for lawful purposes, so too may evidence of
          how often Americans actually deploy that weapon for
          such purposes be relevant to that question. See Vermont

2024 WL 2150522
, *2 n.5 (D. Vt.
          May 14, 2024) (although relevant question may be ‘‘what
          weapons are chosen [by] Americans for self-defense,
          not what weapons are deployed or fired in self-defense
          . . . the frequency at which weapons are fired in self-defense is still relevant to the question of which weapons are used in self-defense’’ (citation omitted; emphasis in original; internal quotation marks omitted)),

 (2d Cir. July 31, 2024)

          that the former type of evidence is entitled to greater
          weight than the latter, ‘‘[i]t is the exclusive province of
          the [trial court on remand] to weigh the conflicting
          evidence, determine the credibility of witnesses and
          determine whether to accept some, all or none of a
          accessory for self-defense, while relevant, also cannot be dispositive in
          assessing whether a firearm or firearm accessory is in common use for self-defense’’ and concluding that large capacity magazines are not commonly
          used for self-defense because, although ‘‘many Americans purchase [them]
          with the intent to use them for self-defense . . . it is exceedingly rare . . .

          whether ‘‘law-abiding citizens buy the weapons at issue for the purpose of
          defending themselves, or because the weapons’ characteristics are well-suited for some unlawful purpose,’’ and, once purchased, whether those
          firearms are ‘‘actually used for self-defense, or are . . . more often utilized
          to achieve unlawful ends’’ (emphasis added)).

       self-defense, or the magnitude of their deterrent effect
       . . . but relevance of other considerations to the ultimate inquiry creates a question of weight, not relevance’’ (citation omitted; emphasis omitted; internal
       quotation marks omitted)).
          In sum, courts have considered a number of factors
       to determine whether the weapons at issue were in
       common use for lawful purposes like self-defense,
       which factors tend to show both ‘‘how’’ and ‘‘why’’ a
       particular weapon is used or possessed, including, but
       not limited to, evidence demonstrating whether American citizens typically possess, or own, the weapon and
       the subjective reasons for such ownership. We agree
       that such evidence can be helpful in making the factual
       determination as to whether the weapon is in common
       use for a lawful purpose. At the same time, we do not
       believe that this constitutes an exhaustive list of the
       factors that the court can consider; nor is any combination of these factors dispositive of the common use
       question. Ultimately, it is the function of the trial court
       on remand, applying the rules of evidence, to decide
       whether the evidence presented by the parties is relevant to the common use inquiry and to credit the evidence that it finds most persuasive.
          The defendant’s burden on remand, then, is to demonstrate as a threshold matter that (1) the silencers and
       large capacity magazines that he possessed are ‘‘arms’’
       as Heller defined that term or, alternatively, are necessary or essential to use a constitutionally protected
       firearm, and (2) the silencers, large capacity magazines,
       and AR-15 style rifles that he possessed or sold are in

          common use or typically possessed today for lawful
          purposes. The state may then present evidence to rebut
          that showing. The court must weigh the evidence presented by the parties to determine whether it weighs
          in favor of second amendment protection. If the court
          concludes at step one that the second amendment does
          not apply, the analysis ends there. Alternatively, if the
          court concludes that any of the firearms or related
          components at issue are ‘‘arms’’ in common use or
          typically possessed for lawful purposes, then the second amendment presumptively protects those items,
          and the court must proceed to Bruen’s second step, to
          which we now turn briefly.
                                        B
             As clearly set forth in Bruen, if the second amendment presumptively protects the defendant’s conduct,
          the burden then shifts to the state to demonstrate that
          its regulation of that conduct ‘‘is consistent with the
          [n]ation’s historical tradition of firearm regulation.’’
          New York State Rifle & Pistol Assn., Inc. v. 
Bruen, supra,
 
597 U.S. 24
. On remand, the parties will have an
          opportunity to develop the historical record for the
          purpose of collecting historical analogues to the challenged statutes. In assessing these analogues, the court
          must consider ‘‘whether the challenged regulation is
          consistent with the principles that underpin our regulatory tradition,’’ or, in other words, ‘‘is relevantly similar
          to laws that our tradition is understood to permit
          . . . .’’ (Internal quotation marks omitted.) United
          States v.

          inquiry is ‘‘how and why the regulations burden a law-abiding citizen’s right to armed self-defense’’; that is,
          ‘‘whether modern and historical regulations impose a
          comparable burden on the right of armed self-defense
          and whether that burden is comparably justified . . . .’’

       carried its burden, it must uphold the regulation as
       constitutional.50
          The parties do not dispute the nature of the inquiry
       at Bruen’s second step to the same extent that they
       dispute the nature of the step one inquiry. We find
       it necessary, however, to briefly address two of the
       defendant’s arguments about the minimal historical
       analysis that the state sets forth in its appellate brief.
       We will address each argument in turn.
          First, the defendant argues that the state cannot carry
       its burden by presenting historical regulations of nonfirearm weapons such as knives. We do not read Bruen’s
       test so rigidly. The Supreme Court emphasized in Bruen
       that the state must only ‘‘identify a well-established and
       representative historical analogue’’ to a modern-day
       regulation, not ‘‘a historical twin’’ or ‘‘a dead ringer
       . . . .’’ (Emphasis in original.) 
Id., 30
. As the court
       recently reiterated in Rahimi, ‘‘when a challenged regulation does not precisely match its historical precursors,
       it still may be analogous enough to pass constitutional
       muster.’’ (Internal quotation marks omitted.) United
       States v. 
Rahimi, supra,
 
144 S. Ct. 1898
. Indeed, in
       Bruen, the Supreme Court suggested that a historical
       regulation of nonfirearm weapons may be a sufficiently
       comparable analogue to a modern firearm regulation.
          50
             Although we have greatly simplified our explanation of Bruen’s second
       step, we acknowledge that the practical application of the history and tradition test is not, by any means, a simple task for a trial court. We echo Justice
       Jackson’s sentiment, expressed in her concurring opinion in Rahimi, that
       ‘‘courts, which are currently at sea when it comes to evaluating firearms
       legislation, need a solid anchor for grounding their constitutional pronouncements.’’ United States v. 
Rahimi, supra,
 
144 S. Ct. 1930
. Until the United
       States Supreme Court issues clearer guidance on how to conduct Bruen’s
       test, however, it is our job, and the job of the trial court, to apply that test
       as we are best able to understand it. We do not underestimate the difficult
       burden confronting the trial court on remand. And, although we do not
       expect that we have addressed in this opinion every issue that will arise
       on remand, we hope that our guidance eases at least some of the heavy
       burden the Bruen test imposes.

                                 State v. Giannone

          See New York State Rifle &; Pistol Assn., Inc. v. 
Bruen, supra,
 597 U.S. 40–42. Specifically, the court concluded
          that a medieval English statute prohibiting ‘‘rid[ing] or
          go[ing] . . . armed’’ was ‘‘not sufficiently probative to
          defend New York’s proper-cause requirement.’’ (Internal quotation marks omitted.) 
Id., 40
. Aside from the
          fact that the statute was enacted more than 450 years
          before the constitution’s ratification and thus ‘‘ha[d]
          little bearing on the [s]econd [a]mendment,’’ the court
          reasoned that the medieval prohibition appeared to ‘‘focus
          on armor and, perhaps, weapons like launcegays,’’ both
          of which, unlike handguns, ‘‘were generally worn or
          carried only when one intended to engage in lawful combat
          or . . . to breach the peace.’’ 
Id., 41
. The court noted
          that the government had presented ‘‘no evidence suggesting the [medieval] [s]tatute applied to the smaller
          medieval weapons’’—namely, a knife or dagger, which
          almost everyone during medieval times carried in their
          belts and were often worn by civilians for self-protection—‘‘that str[uck] [the court] as most analogous to modern handguns,’’ which were not in existence
          during the medieval period. 
Id.,
 41–42. Thus, the court
          implied that, if the historical regulation had applied to
          the types of medieval weapons that the court viewed
          as ‘‘most analogous to modern handguns,’’ it may have
          been a more persuasive historical analogue for the modern-day handgun regulation. 
Id., 42
.
             Accordingly, to prevail on remand, it is not necessary
          for the state to present a ‘‘historical twin’’ that regulates
          the same type of weapon as does the challenged regulation. The central considerations, rather, are ‘‘whether
          modern and historical regulations impose a comparable
          burden on the right of armed self-defense and whether
          that burden is comparably justified . . . .’’ 
Id., 29
. If a
          court concludes that a historical knife regulation and
          a modern firearm regulation comparably burden that
          right, and that the burden is comparably justified, then

                             State v. Giannone

       that historical regulation may be sufficiently analogous
       to the modern regulation to pass Bruen’s test. Indeed,
       if the regulated firearm was not in existence at the time
       of the second amendment’s ratification, resorting to
       historical analogues of nonfirearm weapons may be the
       only way in which the state can satisfy its burden.

           Second, the defendant claims that the state’s arguments about technological developments and using a
       ‘‘ ‘nuanced approach’ ’’ to analytical reasoning in effect
       ask this court to adopt the type of means-end scrutiny
       that Bruen prohibits. We disagree. To be sure, other
       courts have recognized that Bruen’s instruction to look
       for a historical analogue that imposes a comparable
       burden that is comparably justified in relation to the
       challenged regulation resembles a means-end balancing
       test despite the court’s express rejection of such means-end balancing in the second amendment context. See,
       e.g., Bevis v. 
Naperville, supra,
 
85 F.4th 1199
 (‘‘[f]or all
       its disclaiming of balancing approaches, Bruen appears
       to call for just that: a broader restriction burdens the
       [s]econd [a]mendment right more, and thus requires a
       closer analogical fit between the modern regulation and
       traditional ones; a narrower restriction with less impact
       on the constitutional right might survive with a looser
       fit’’). Nevertheless, the Supreme Court expressly provided for ‘‘a more nuanced approach’’ for cases that,
       unlike Bruen and Heller, do not involve analogies that
       are ‘‘relatively simple to draw’’ but, rather, ‘‘implicat[e]
       unprecedented societal concerns or dramatic technological changes . . . .’’ New York State Rifle & Pistol
       Assn., Inc. v. Bruen, supra, 
597 U.S. 27
. The court cautioned, however, that ‘‘[t]his does not mean that courts
       may engage in independent means-end scrutiny under
       the guise of an analogical inquiry. . . . Analogical reasoning requires judges to apply faithfully the balance

          struck by the founding generation to modern circumstances . . . . It is not an invitation to revise that balance through means-end scrutiny.’’ (Citations omitted.)
          Id., 29 n.7.
             Finally, we note that, although ‘‘common use,’’ ‘‘typical possession,’’ and ‘‘dangerous and unusual’’ must be
          addressed at Bruen’s first step, they also may be relevant to Bruen’s second step for the purposes of identifying historical analogues that impose a comparable
          burden on the second amendment right and are comparably justified. For instance, even if a weapon is ‘‘in
          common use,’’ a court may nonetheless consider the
          unusually dangerous character of a weapon, or its militaristic features, at Bruen’s second step. Although the
          United States Supreme Court recognized a historical
          tradition of prohibiting the carrying of dangerous and
          unusual weapons, neither Bruen nor Heller precludes
          the state from meeting its burden by demonstrating
          through historical analogues that this country also has a
          historical tradition of regulating particularly dangerous
          weapons or of reserving certain weapons for military
          or law enforcement use. See, e.g., Bevis v. Naperville,
          supra, 
85 F.4th 1199
, 1201 (considering common use at
          both steps of analysis without deciding where it
          belongs, and concluding at step two that there are longstanding traditions of regulating especially dangerous
          weapons and of distinguishing between military or law
          enforcement access to and civilian ownership of such
          weapons); National Assn. for Gun Rights v. Lamont,
          supra, 
685 F. Supp. 3d 90
 n.11 (‘‘even if a weapon must
          be dangerous and unusual to fall under the already
          enumerated [s]econd [a]mendment exception from
          Heller,’’ as opposed to dangerous or unusual, ‘‘it is consistent with the nation’s tradition and history of firearm
          regulation to regulate narrow and specific categories
          of unusually dangerous weapons resulting from developments in firearm technology’’ (emphasis omitted)).

       Additionally, to satisfy its burden of identifying a historical analogue that imposes a comparable burden on the
       right to keep and bear arms, it may be necessary to
       assess whether the historically regulated arms were,
       like the modern regulated arms, in common use for
       lawful purposes at the time of the historical regulation.
       See New York State Rifle & Pistol Assn., Inc. v. Bruen,
       supra,

 (rejecting historical analogue where
       there was no evidence that it applied to ‘‘the smaller
       medieval weapons that str[uck] [the court] as most
       analogous to modern handguns’’).
         The judgments are reversed and the cases are
       remanded for further proceedings consistent with this
       opinion.
         In this opinion the other judges concurred.
