If you are 18 in Michigan, you can buy a rifle or shotgun from a licensed dealer or a private seller, but you cannot buy a handgun from a dealer. Federal law bars any federally licensed dealer from selling a handgun or handgun ammunition to anyone under 21.1Office of the Law Revision Counsel. 18 USC 922 Michigan does let 18-year-olds acquire a handgun through a private sale, but only after going through the state’s License to Purchase process. So the real question when buying a gun in Michigan at 18 is not just what you want, but where you are getting it and from whom.
Rifles and Shotguns at 18
Federal law permits licensed dealers to sell rifles and shotguns to anyone 18 or older.1Office of the Law Revision Counsel. 18 USC 922 Michigan sets the same floor for long guns, defined as firearms with an overall length greater than 26 inches. At a dealer, you show a valid photo ID, complete ATF Form 4473, and pass a background check.2Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF Form 4473 – Firearms Transaction Record Revisions
Buying a long gun from a private seller, such as a neighbor or someone at a gun show, is also legal at 18, but Michigan’s 2023 reforms changed the paperwork. Public Act 19 of 2023 extended the state’s License to Purchase requirement to all private firearm sales, not just handguns.3Michigan Legislature. House Bill 4138 of 2023 (Public Act 19 of 2023) So a private rifle purchase now requires the same license a private handgun purchase does.
Handguns at 18
No licensed dealer in Michigan can sell you a handgun until you turn 21. That is a federal rule, and state law cannot override it.1Office of the Law Revision Counsel. 18 USC 922 The same rule blocks you from buying handgun ammunition at a dealer.
Federal law does allow private (unlicensed) sellers to transfer handguns to buyers 18 and older, and Michigan permits this if you go through the License to Purchase process.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Minimum Age for Gun Sales and Transfers One thing to note about Michigan’s definition: a “pistol” is any firearm with an overall length of 26 inches or less. That sweeps in some short-barreled configurations that don’t look like traditional handguns. If the firearm is 26 inches or under, the pistol rules apply.
How the License to Purchase Works
The License to Purchase (Michigan form RI-10A) is how the state runs a background check on a private sale. At 18, you need one for any private firearm purchase, whether the gun is a rifle, a shotgun, or a pistol. Older buyers can skip it only if they hold a valid Concealed Pistol License, and a CPL requires being 21.5Bloomfield Township. Bloomfield Township – Gun Registration
To get one, go to your local city or township police department, or your county sheriff’s office. Bring a valid Michigan driver’s license or state ID. You’ll complete the application under oath. It asks about felony convictions, domestic violence history, mental health adjudications, and any court orders that would disqualify you. If your background check comes back clean, the agency issues the license. It is valid for 30 days, so plan your purchase within that window.5Bloomfield Township.

Completing a Private Sale
When you show up to buy, the seller should verify your License to Purchase before handing anything over. The transaction is documented on a three-part Michigan State Police form: one copy for the buyer, one for the seller, and one designated the Licensing Authority Copy.6City of Ann Arbor. Firearm Permits and Licenses
For pistol sales, the seller is the one legally responsible for returning the Licensing Authority Copy to local law enforcement within 10 days of the sale, either in person or by first-class or certified mail. Failing to return the form is a civil infraction with a fine of up to $250.7Michigan Legislature. Michigan Compiled Laws 28.422a The duty is the seller’s, but it is worth following up, because the returned form is what officially registers the pistol.
Extra Background-Check Steps for Under-21 Buyers
Even a straightforward long-gun purchase at a dealer can take longer at 18 than it does at 25. The Bipartisan Safer Communities Act of 2022 requires the FBI’s NICS system to run a deeper check on buyers under 21. Examiners reach out to state juvenile justice agencies, mental health repositories, and local law enforcement to look for disqualifying records that don’t show up in the national databases.8Federal Bureau of Investigation. NICS Enhanced Background Checks for Under-21 Gun Buyers Showing Results
If the standard check does not clear within three business days, examiners get up to 10 business days total to finish the enhanced review before the dealer can proceed.8Federal Bureau of Investigation. NICS Enhanced Background Checks for Under-21 Gun Buyers Showing Results Most transactions still clear the same day. If you have any juvenile history, expect the possibility of a delay.
Straw Purchases Are a Serious Federal Crime
Because dealers won’t sell handguns to anyone under 21, some 18-year-olds ask an older friend or relative to buy one for them. That is a straw purchase, and federal law treats it as a standalone felony. Under 18 U.S.C. § 932 and § 933, a straw purchase carries up to 15 years in prison and a $250,000 fine. If the firearm is later used in a violent felony, drug trafficking, or terrorism, the maximum climbs to 25 years.9Bureau of Alcohol, Tobacco, Firearms and Explosives. Don’t Lie for the Other Guy Both the buyer and the recipient can be charged.
Who Cannot Buy a Firearm at Any Age
Some records will disqualify you regardless of whether you are 18, 21, or older. The ones most likely to matter for a young buyer:
- A standard felony conviction bars firearm possession until three years after you complete your full sentence, including fines, probation, and parole. A “specified felony” carries a five-year bar and requires a court order restoring your firearm rights.10Michigan Legislature. Michigan Compiled Laws 750.224f
- A misdemeanor domestic violence conviction triggers an eight-year prohibition on firearms and ammunition, starting after fines, jail time, and probation are complete.10Michigan Legislature. Michigan Compiled Laws 750.224f
- Being judged legally incapacitated or involuntarily committed for mental health treatment blocks possession unless a court restores your legal capacity.
- A personal protection order or an Extreme Risk Protection Order (authorized by Michigan’s 2023 ERPO Act) requires you to surrender firearms while the order is in effect.11Michigan Legislature. Michigan Compiled Laws Act 38 of 2023 – Extreme Risk Protection Order Act
Convictions that have been expunged, set aside, or pardoned generally don’t count against you, unless the order specifically preserves the firearm restriction.10Michigan Legislature. Michigan Compiled Laws 750.224f If any of these apply to you, resolve your eligibility with a lawyer before you try to buy or receive a firearm.
