Is a Montana Non-Resident Permit Valid in Illinois?

Why

• Montana does not issue carry permits to non-residents (permit requires at least 6 months' montana residency, us citizenship or lawful permanent residence, and montana id (mca 45-8-321; mt doj). no non-resident permits are issued).

ISP (official 2025 brochure): 'Illinois does not recognize concealed carry licenses from other states.' Sole carve-out: a resident of another state with a valid concealed carry license from their home state may carry a concealed firearm within a vehicle while traveling through Illinois; if the vehicle is left unattended the firearm must be stored in a locked vehicle or locked container out of plain view (430 ILCS 66).

Carry rules in Illinois

Crossing into Illinois swaps the rulebook. Here is what changes for a visiting carrier.

• Disclosure is on-demand only: upon an officer's request during a stop, the licensee or qualifying non-resident must disclose that they possess a concealed firearm, present the license on request, identify the firearm's location, and permit the officer to secure it for the stop (ISP brochure, per the Concealed Carry Act).
• Illinois limits magazine capacity to 15 rounds — a limit that applies to visitors, and one of the easiest laws to break by accident.
• Illinois is not a permitless-carry state: concealed carry there requires a permit Illinois recognizes.
• Illinois CCL holders may carry loaded and concealed in a vehicle; non-residents with a valid home-state license may carry loaded/concealed only within a vehicle; everyone else must transport firearms unloaded and enclosed in a case (or broken down / not immediately accessible).
