Yes, pepper spray is legal in Montana for self-defense, but its purchase, possession, and use are governed by state statutes and local ordinances. Residents may acquire non-toxic, commercially manufactured sprays containing oleoresin capsicum (OC) under 2% concentration. However, the Montana Department of Justice mandates compliance with concealed carry laws if the spray is carried in a manner resembling a firearm.
Key Regulations for Pepper Spray in Montana
- Concentration Limits: OC concentration must not exceed 2%, with a maximum canister capacity of 2 fluid ounces. Products exceeding this threshold are classified as prohibited weapons under MCA § 45-8-213.
- Age Restrictions: Only individuals aged 18 or older may purchase or possess pepper spray. Retailers must verify age via government-issued ID, per the Montana Attorney General’s 2024 retail compliance guidelines.
- Use Prohibitions: Spray may not be deployed against law enforcement or in the commission of a crime. Unlawful use triggers felony charges under MCA § 45-5-210, with penalties escalating if harm results.
Local jurisdictions, such as Missoula and Bozeman, impose additional restrictions on public display or brandishing. The 2026 Montana Legislative Session may introduce amendments to OC spray regulations, particularly concerning carry visibility and training requirements. Consult the Montana Code Annotated and local law enforcement for updates.
