Is It Legal to Carry a Gun in Your Car in Montana? (2026)

Short answer: Yes. Montana is a permitless-carry state, and it’s one of the cleanest in the country for vehicle carry. An eligible adult can keep a loaded handgun in their vehicle — openly or concealed — with no permit required. A holstered handgun sitting in plain view is perfectly legal here. Here’s the detail for 2026.

Do you need a permit to carry a gun in your car in Montana?

No. Montana adopted permitless carry when House Bill 102 took effect in 2021. An adult who is legally allowed to possess a firearm may carry a handgun — concealed or openly — without a license. The general threshold is 18 or older.

Montana has no prohibition on carrying a loaded firearm in a motor vehicle — on your person, in the glovebox, under the seat, or anywhere else in the car. And because open carry is also legal statewide for anyone who can lawfully possess a firearm, you don’t even need to conceal it — a holstered handgun in the open is fine.

An optional Montana Concealed Weapon Permit is still available, mainly for reciprocity when you travel to other states.

Loaded or unloaded? Open or concealed?

Montana does not require the handgun to be unloaded, and it does not force you to choose concealed or open in your vehicle — both are legal for an eligible carrier. You can keep a loaded handgun:

• holstered in plain view (including in a cup holder holster)
• concealed on your person, or
• in the console, glovebox, or elsewhere in the vehicle

That “open carry is fine” point is what makes Montana such a natural fit for a vehicle holster — you’re never fighting a concealment requirement.

A note on drivers 18 to 20

Montana’s permitless open carry is generally available to eligible adults 18 and older. If you’re in that group, a holstered handgun carried openly — like one in a cup holder — is the lane that fits. Confirm the current rule for your situation.

Who can’t carry in a vehicle

The permitless-carry protection applies to people who can lawfully possess a firearm. It does not extend to prohibited persons — for example, those with a disqualifying felony conviction or another state/federal disqualifier.

Where you still can’t take it

Permitless carry doesn’t override location limits. Montana still restricts firearms in places like courthouses, secured federal facilities, schools, and other posted or statutorily restricted locations. Carrying in your car gets you there; it doesn’t get you inside a prohibited place.

The practical problem: where do you keep it while driving?

Montana makes the legal side easy. The practical side is universal: sit down, buckle up, and a hip holster gets pinned under the belt and slow to reach. The usual fallback — dropping the gun in the console or door pocket — leaves it unholstered, trigger exposed, and sliding around.

A cup holder holster keeps the firearm holstered, secured, and within reach in your cup holder. Because Montana allows open carry, a holstered handgun in plain view is fully legal — no concealment gymnastics required. No drilling, and it moves from the truck to the daily driver in seconds.
