Yes, blank firing guns are legal in Montana under state law, provided they comply with federal regulations and local ordinances. Montana does not explicitly ban blank-firing firearms, but their use must align with concealed carry statutes and local noise ordinances.
Key Regulations for Blank Firing Guns in Montana
- Federal Compliance: Blank-firing devices must adhere to ATF regulations, including the absence of a projectile and compliance with the National Firearms Act (NFA) if modified to fire live ammunition.
- Local Noise Ordinances: Cities like Billings and Missoula enforce decibel limits; blank firing exceeding 85 dB may violate municipal codes.
- Concealed Carry Restrictions: While blank guns are not classified as firearms under Montana law, using them in a manner that simulates a firearm (e.g., in public) may trigger disorderly conduct charges under MCA § 45-8-212.
Montana’s 2025 legislative session introduced HB 321, which clarified that blank-firing guns are exempt from concealed carry permitting if designed solely for blank ammunition. However, retailers must verify compliance with the Montana Department of Justice’s 2026 firearms dealer guidelines. Misuse—such as brandishing a blank gun in a threatening manner—remains prosecutable under aggravated assault statutes (MCA § 45-5-202). Always consult county sheriff offices for jurisdiction-specific restrictions.
