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.
