Permit & Carry Requirements

Montana is a constitutional carry state where no permit is required for eligible persons 18 and older to carry a concealed firearm. Open carry is also permitted. Montana issues a voluntary Concealed Weapons Permit (CWP) through county sheriffs for residents who want a permit for reciprocity in permit-required states.

Reciprocity

Montana honors concealed carry permits from all US states. The Montana CWP is recognized by a number of states across the country. Non-residents 18 and older may carry in Montana under its constitutional carry provisions while visiting the state.

Prohibited Locations

Montana prohibits carry in courthouses, detention facilities, schools and on school grounds, financial institutions, and any posted private property. Montana's list of prohibited locations is relatively short compared to many other states, reflecting its strong firearms culture.

NFA Items in Montana

Montana permits federally-registered NFA items including suppressors, SBRs, and SBSs. Montana has no state-level restrictions on NFA items beyond federal requirements and no magazine limits or assault weapon ban. The $200 NFA tax stamp elimination effective January 1, 2026 benefits Montana residents.
