Is a Montana Resident Permit Valid in Louisiana?

Why

• Louisiana's official reciprocity list includes Montana.
• Louisiana honors out-of-state permits only for holders 21 and older, and Montana issues this permit from age 18.
• Louisiana allows permitless carry for eligible adults 18+, which extends to visitors who may legally possess a handgun.

R.S. 40:1379.3(T)(2): a current, valid permit issued by another state to a holder aged 21+ is valid in Louisiana only if Louisiana's permit is valid in that state (mutual recognition - LSP publishes the list of 37 states). The statute does not require the holder to be a resident of the issuing state. (T)(4): an out-of-state permit is invalid for a LOUISIANA resident. Since July 4, 2024 any non-prohibited person 18+ may carry permitless regardless of permits.

Carry rules in Louisiana

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

• Louisiana imposes a duty to inform: you must tell an officer you are carrying. R.S. 40:1379.3(I)(2): a permittee - and anyone carrying under permitless R.S. 14:95(M) - must notify any police officer who approaches in an official manner that they have a weapon, submit to a pat-down and allow the officer to temporarily disarm them. Failure triggers automatic 6-month permit suspension for permittees.
• Louisiana sets no state magazine-capacity limit for handguns.
• Louisiana allows permitless concealed carry from age 18 for people who may legally possess a handgun, including eligible visitors.
• Carrying a handgun in a motor vehicle is legal under most circumstances (LSP FAQ), and the 18+ permitless-carry provision applies in vehicles; the statutory duty to inform applies on any official police contact.

Off-limits places in Louisiana

Louisiana bans carry in 6 kinds of places. The first on the list:

• Law enforcement offices, stations or buildings; detention facilities, prisons and jails (R.S. 40:1379.3(N))
• Courthouses and courtrooms

Montana vs Louisiana: what changes at the state line

Frequently asked questions

Does Louisiana honor a Montana non-resident permit?

Montana does not issue non-resident carry permits (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), so the question does not arise.

Can a Louisiana resident permit holder carry in Montana?

Recognized — and permitless carry applies. Reciprocity is decided by the destination state, so the answer in this direction depends on Montana's law, not Louisiana's.

Where does Louisiana publish its official reciprocity list?

Louisiana 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.
