Yes, stun guns are legal in Montana for individuals 18 or older without a permit. Montana’s lack of restrictive statutes contrasts with neighboring states, though local ordinances in cities like Billings or Missoula may impose additional constraints. As of 2026, no pending legislation targets stun gun ownership, but compliance with state firearm laws remains advisable.
Key Regulations for Stun Guns in Montana
- Age Requirement: Users must be at least 18 years old; minors are prohibited from possession.
- Prohibited Locations: Use or carry is banned in government buildings, schools, and courthouses under Montana Code Annotated § 45-8-306.
- Concealed Carry: No permit is required for open or concealed carry, but brandishing in a threatening manner may violate disorderly conduct laws.
Local law enforcement agencies, including the Missoula County Sheriff’s Office, enforce these rules with discretion. While state law preempts municipal restrictions, some counties have issued advisories on responsible use. Violations typically result in misdemeanor charges, with penalties up to $500 or 6 months imprisonment. Retailers must verify age via ID checks, per Montana’s 2023 retail compliance guidelines.
