Montana Permitless Carry and the Concealed Weapon Permit

Montana is a permitless carry state and has been since 2021. That single fact answers most questions, and then raises a harder one: if no permit is required, why do so many Montanans still hold a concealed weapon permit from their county sheriff? There are three real answers, and they are worth understanding before you decide. General information, not legal advice; the law described here is current as of September 2026. For the wider picture, see our Montana firearm law overview.

What permitless carry actually covers

House Bill 102 amended MCA 45-8-316 in 2021. The section still defines carrying a concealed firearm as a misdemeanour, but it now adds that the section does not apply to a person eligible to possess a firearm under state or federal law. The Montana Department of Justice states it plainly: Montana law allows any person to carry a weapon concealed without a permit, so long as that person is eligible to possess a firearm.

Eligible means exactly what it means at the dealer counter. If a federal or state prohibition applies to you, permitless carry does not reach you, and a concealed firearm becomes a criminal charge rather than a lawful choice. There is no minimum age written into the carry exemption beyond eligibility to possess, which is why the practical age floor differs from the 21-year floor on buying a handgun from a dealer.

What permitless carry does not cover

Four categories of place stay closed, and a permit only helps with one of them.

State and local government buildings. Under MCA 45-8-328, carrying a concealed weapon into a restricted portion of a building used for state or local government offices is an offence. The exemption in that section runs to permit holders. Without a permit, you cannot.
Courts. Carrying concealed into a courtroom or a space controlled by a Montana court is unlawful unless the judge in charge orders otherwise. A permit does not change this.
Public schools. MCA 45-8-361 makes it an offence to possess, carry or store a weapon in a school building, with narrow exceptions for law enforcement, school marshals and people the trustees have given advance permission. A permit does not change this either.
Federal buildings. Off limits under federal law regardless of what Montana says.

University campuses sit in their own category. HB 102 tried to remove the Board of Regents' authority over firearms on Montana University System campuses, that provision was litigated, and the courts sided with the Board. The Board of Regents policy on campus security and firearms governs, so read it rather than assuming state carry law applies.

Reason one: other states

This is the most common reason people still apply. A Montana permit is recognised by a number of other states, and their recognition usually depends on you holding a permit rather than on Montana allowing permitless carry. If you drive to see family in a state that does not honour permitless carry, the plastic card in your wallet is what keeps the trip lawful.

The Department of Justice is careful on this point, and so should you be: Montana residents who want to know whether their permit is valid in another state must check with that specific state. Reciprocity lists change without notice. Check before every trip, not once a decade.

Montana's side of reciprocity is set out in MCA 45-8-329. The Attorney General recognises concealed weapon permits from states whose law requires a criminal records background check before issuing. The permit must be in the holder's immediate possession and the holder must carry photo identification. Permits from a handful of states are not recognised because their law does not expressly require that background check.

Reason two: the background check exemption

Federal law lets a state permit stand in for a NICS check at the dealer counter, if the permit qualifies and was issued no more than five years before the transfer. ATF publishes the list of qualifying permits on its Brady permit chart, and Montana's concealed weapon permit has appeared there. Because the chart is revised and because dealers apply the five-year rule strictly, treat this as something to confirm rather than assume. Ask your dealer whether they will accept your permit in place of the check, and expect the answer to depend on the issue date printed on the card.

When it works, the practical effect is a faster transfer with no waiting on the system. When it does not, nothing is lost; the dealer simply runs the check as normal.

Reason three: it settles arguments

A permit is state-issued proof that a sheriff ran a background check on you and that you demonstrated familiarity with a firearm. That is not a legal requirement for carrying in Montana, but it removes friction in the situations where friction matters.

How to get a permit from the {county} County Sheriff

Applications come from the sheriff's office, and the statutory form is set out in MCA 45-8-322. The requirements under MCA 45-8-321 are straightforward:

At least 18 years old.
A resident of Montana for at least six months.
A United States citizen or permanent lawful resident, with valid state identification.
Proof of familiarity with a firearm.

That last item has several accepted routes: a hunter education or safety course from FWP or an equivalent state agency, a firearms safety course approved by a state wildlife agency, a national firearms association, a law enforcement agency, a college or a nationally certified instructor, a law enforcement firearms course, a valid concealed carry licence from another state granted on equivalent training, or evidence of military firearms qualification including handguns. A sheriff may also accept a physical demonstration of familiarity.

Cost and term

The statute sets $50 for issuance and $25 for each renewal, in four-year periods. A sheriff may require fingerprints and may charge $5 for them. Renewal is made within 90 days before expiry, with a 30-day grace period after. Individual offices differ on scheduling, accepted payment and how fast they process, so call the {county} County Sheriff before you drive over.

Practical notes

Montana has no prohibition on carrying a weapon in a motor vehicle. Local governments retain narrow authority over carrying in publicly owned and occupied buildings, and the Department of Justice advises checking local regulations, so the sheriff's office is the right first call when you move to a new county. If you are buying a carry gun, holster and ammunition together, the catalog lists what ships to your door and what has to route through a dealer, and the shop page explains the transfer process.

None of this is a substitute for reading the statute. MCA 45-8-316, 45-8-321, 45-8-322, 45-8-328, 45-8-329 and 45-8-361 are short and free to read.
