Can You Carry a Gun in Montana?

Open Carry Gun Laws in Montana

Open carry is legal in Montana without a permit for anyone at least 18 years old who can legally own a firearm with several restrictions. Some areas are off-limits, including schools and federal buildings.

Stand Your Ground

Montana is a Castle Doctrine state and has a “stand your ground” law. A person is justified in the use of force likely to cause death or serious bodily harm only if the person reasonably believes that the force is necessary to prevent the commission of a forcible felony. 

The law applies in an occupied structure, personal property lawfully in the person’s possession or in the possession of another who is a member of the person’s immediate family or household, or of a person whose property the person has a legal duty to protect. 

A person who is lawfully in a place or location and who is threatened with bodily injury or loss of life has no duty to retreat from a threat or to summon law enforcement assistance prior to using force.

Gun Purchase and Handgun Registration Requirements

No permit is needed to purchase a firearm from a private individual. There is no waiting period and no firearms registration in the state. Background checks are not required for private sales. Background checks are required for anyone without a MCWP when purchasing a handgun from a Federal Firearms Dealer (FFL). There is no requirement to inform law enforcement that you are carrying a firearm in Montana.

There is no Montana state law regarding age restrictions on the purchase or possession of firearms. However, it is unlawful for a parent, guardian or other person having charge or custody of a minor child under the age of 14 years to permit the minor child to carry or use in public any firearms. That is except when the child is accompanied by a person having charge or custody of the child or under the supervision of a qualified firearms safety instructor or an adult who has been authorized by the parent or guardian. 

Per federal law, dealers may not sell handguns to anyone under the age of 21 and private sellers may not sell handguns to anyone under the age of 18.

Less-Lethal Legal Self-Defense Weapons

Pepper spray, stun guns and Tasers are legal to purchase and possess without a permit.
