Is a Colorado Resident Permit Valid in Montana?

Why

• Montana's official reciprocity list includes Colorado.
• Montana allows permitless carry, which extends to visitors who may legally possess a handgun.

MCA 45-8-329 recognizes another state's permit if that state requires a criminal-records background check before issuance and the holder carries the permit plus photo ID; it imposes no issuing-state residency condition. The AG list (last updated Oct 2024) excludes Delaware, District of Columbia, Hawaii, Maine, New Hampshire and Rhode Island because their laws do not expressly require background checks; Vermont issues no permits. Recognition is largely moot for eligible adults because carry is permitless.

Frequently asked questions

Does Montana honor a Colorado non-resident permit?

Colorado does not issue non-resident carry permits (No non-resident permits. Armed-forces members stationed in Colorado on permanent duty station orders, and their immediate family living in Colorado, are deemed legal residents (C.R.S. 18-12-203(1)(a))), so the question does not arise.

Can a Montana resident permit holder carry in Colorado?

Recognized — holders 21+ only. Reciprocity is decided by the destination state, so the answer in this direction depends on Colorado's law, not Montana's.

Where does Montana publish its official reciprocity list?

Montana publishes its recognition policy on an official state page, linked in the sources on this page. That page is the authority — check it shortly before travel, because recognition lists change without much notice.
