Is a South Dakota Resident Permit Valid in Montana?

Why

• Montana's official reciprocity list includes South Dakota.
• 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 South Dakota non-resident permit?

South Dakota does not issue non-resident carry permits (no non-resident permits — the applicant must have physically resided in and be a resident of the county of application for at least 30 days immediately preceding the application (SDCL 23-7-7.1)), so the question does not arise.

Can a Montana resident permit holder carry in South Dakota?

Recognized — and permitless carry applies. Reciprocity is decided by the destination state, so the answer in this direction depends on South Dakota'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.
