Mont. Code Ann. § 27-17-102

Parts 2, 3, and 4 of this chapter and Rule 55(b)(2), M.R.Civ.P., are applicable to a claim to recover personal property when made in justices' courts, and the powers given in those statutes and rules and the duties imposed on sheriffs are extended to constables and the word "justice" is substituted for "judge". The justice, instead of the plaintiff or the plaintiff's attorney, may, by an endorsement in writing upon the affidavit, order the sheriff or constable to take the property mentioned in the affidavit.
