Montana Gun Laws in Plain English
In Montana, you can carry a concealed firearm without a permit if you are legally allowed to own a gun. You can buy firearms without a waiting period or purchase permit, and private sales do not require a background check. There are no limits on the type of firearms or magazines you can own. However, you cannot carry on university campuses or in federal buildings, and you must be careful about carrying while consuming alcohol.
Critical: Montana Gun Law Gotchas
These are the most important things to know that could get you arrested or charged with a crime:
- #1The federal Gun-Free School Zones Act (18 U.S.C. § 922(q)) creates a 1,000-foot 'no carry' zone around every school. Constitutional Carry does NOT exempt you from this federal felony; only a state-issued permit does.
- #2While state law allows carry in bars (Mont. Code Ann. § 45-8-328), it is illegal to carry if you are consuming alcohol or are under the influence.
- #3The Montana University System bans firearms on campuses. This was upheld by the MT Supreme Court (2022 MT 128), so do not rely on state 'Constitutional Carry' laws on college grounds.
- #4Tribal lands (e.g., Flathead, Blackfeet, Crow reservations) are sovereign nations. State carry laws may not apply, and tribal police enforce their own strict regulations.
- #5Marijuana is legal for recreational use in Montana, but using it makes you a 'prohibited possessor' under federal law (18 U.S.C. § 922(g)(3)), banning you from owning guns.
- #6National Parks (Glacier, Yellowstone) allow carry outdoors, but possession in any federal building (visitor centers, restrooms, ranger stations) is a federal crime (18 U.S.C. § 930).
- #7The 'Montana Firearms Freedom Act' (Mont. Code Ann. § 30-20-101) claims guns made and kept in Montana are exempt from federal law. Federal courts struck this down (MSSA v. Holder); do not rely on it to build unregistered suppressors or machine guns.
- #8Private property owners have the absolute right to ban firearms on their premises. If asked to leave, you must comply or face trespassing charges.
- #9While you can carry in a vehicle without a permit, you cannot carry in a commercial vehicle if prohibited by employer policy or DOT regulations.
- #10It is illegal to shoot a firearm within city limits (Mont. Code Ann. § 45-8-343) unless in a designated range or self-defense.
