MT Gun Laws

Montana has some of the most permissive gun laws in the United States. It is a "shall issue" state for concealed carry. The county sheriff shall issue a concealed weapons permit to a qualified applicant within 60 days. Concealed carry is not allowed in government buildings, financial institutions, or any place where alcoholic beverages are served. Carrying a concealed weapon while intoxicated is prohibited. No weapons, concealed or otherwise, are allowed in school buildings. Montana recognizes concealed carry permits issued by most but not all other states. Concealed carry without a permit is generally allowed outside city, town, or logging camp limits. Under Montana law a permit is necessary only when the weapon is " wholly or partially covered by the clothing or wearing apparel ", therefore it is legal to carry and/or keep a firearm inside a vehicle without a permit. If you do not have a CWP it could be considered a violation of the law for you to conceal a gun in a purse or backpack, since the law defines a concealed weapon as one that is "wholly or partially covered by the clothing or wearing apparel of the person carrying or bearing the weapon. As of 2017, the concealed weapons law applies only to firearms, excluding items such as knives, slingshots, billies, etc. from the permit requirement.
Open carry is generally allowed without a permit.
Montana has state preemption of most firearms laws. Local units of government may not prohibit, register, tax, license, or regulate the purchase, sale or other transfer, ownership, possession, transportation, use, or unconcealed carrying of any weapon. However, local governments may restrict the firing of guns, or the carrying of firearms at public assemblies or in public buildings or parks.
Montana has a number of restrictions on lawsuits against firearms manufacturers, dealers, or trade associations. Such lawsuits may be filed by the state, but not by local governments.
Montana House Bill 246, the Montana Firearms Freedom Act, was signed into law by Governor Brian Schweitzer on April 15, 2009, and became effective October 1, 2009. This legislation declares that certain firearms and firearms accessories manufactured, sold, and kept within the state of Montana are exempt from federal firearms laws, since they cannot be regulated as interstate commerce.
