Yes, you can own a gun at 18 in Florida, but you cannot buy one. State law sets the minimum purchase age at 21 for every type of firearm, while possession by an 18-year-old who obtained the gun through a lawful channel is not a crime.1Florida Senate. Florida Code 790.22 – Possession of Firearms by Minor Under 18 Prohibited The distinction between buying and owning is the whole ballgame, and getting it wrong can mean felony charges.
How an 18-Year-Old Can Legally Own a Gun in Florida
Once you turn 18, Florida’s rules on minors possessing firearms stop applying to you.1Florida Senate. Florida Code 790.22 – Possession of Firearms by Minor Under 18 Prohibited If a firearm comes into your hands through a legal route other than buying it from a dealer, you can keep it. The two common paths:
- A genuine gift from a family member or friend.
- An inheritance through a will or estate.
Keep some proof of how you got the gun. A short written note from the person who gave it to you, or probate paperwork showing you inherited it, is worth having if the origin ever comes into question.
Gift vs. Straw Purchase
The line between a legal gift and an illegal straw purchase is thinner than most people assume. If your parent buys a shotgun with their own money and hands it to you for your birthday, that is a gift. If you hand your uncle $600 and he walks into a gun store, tells the dealer the gun is for him, and then passes it to you, that is a straw purchase. Federal law treats straw purchasing as a serious felony, with penalties up to 15 years in prison and a $250,000 fine, rising to 25 years if the gun is later used in a violent crime or drug trafficking.2Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms The ATF investigates these cases actively, and claiming you did not know it was illegal is not a workable defense.3Bureau of Alcohol, Tobacco, Firearms and Explosives.

Why You Cannot Buy From a Dealer Until 21
Section 790.065(13) of the Florida Statutes prohibits anyone under 21 from purchasing a firearm, and bars licensed dealers from selling or transferring one to them.4The Florida Legislature. Florida Code 790.065 – Sale and Delivery of Firearms This covers handguns, rifles, and shotguns alike. Florida’s rule is stricter than federal law, which allows licensed dealers to sell rifles and shotguns to anyone 18 or older and only restricts handguns to buyers 21 and up.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts An under-21 buyer who attempts the purchase commits a third-degree felony, as does the dealer who completes it.6The Florida Legislature. Florida Code 775.082 – Penalties
The Military and Law Enforcement Exemption
Florida carves out a narrow exception. If you are an active servicemember, a law enforcement officer, or a correctional officer as defined by Florida law, you may purchase a rifle or shotgun at 18.4The Florida Legislature. Florida Code 790.065 – Sale and Delivery of Firearms7Florida Department of Law Enforcement. Requirements to Purchase a Firearm The exemption does not cover handguns. An 18-year-old Marine still cannot buy a pistol in Florida. You will need to present valid credentials (military ID, proof of active duty, or law enforcement identification) and clear the standard background check.
What You Can Do With a Gun You Legally Own at 18
At Home
Florida allows anyone not otherwise prohibited to possess a firearm at home or at their fixed place of business.8The Florida Legislature. Florida Code 790.25 – Lawful Ownership, Possession, and Use of Firearms and Other Weapons If anyone under 18 lives in the house or visits regularly, safe storage matters both practically and legally, because Florida imposes criminal liability on adults who negligently store firearms where children can get at them.
In Your Vehicle
You can carry a firearm in your car at 18 as long as it is “securely encased.” Florida defines that term specifically: in a glove compartment (locked or not), snapped in a holster, in a gun case (zippered or otherwise), or in a closed container that needs a lid or cover lifted to open.9The Florida Legislature. Florida Code 790.001 – Definitions A gun sitting loose on the passenger seat does not qualify. The gun cannot be immediately ready to fire; some physical barrier has to sit between you and a functional weapon.
Concealed Carry
Florida went to permitless concealed carry in 2023, but kept the age floor at 21. You cannot carry concealed at 18 under the general rule.10The Florida Legislature. Florida Code 790.01 – Carrying Concealed Weapons The one opening: active servicemembers and honorably discharged veterans qualify at 18.11Florida Department of Agriculture and Consumer Services. Eligibility Requirements for a Florida Concealed Weapon License
Ammunition at 18
Federal rules let anyone 18 or older buy rifle and shotgun ammunition from a licensed dealer. Handgun ammunition requires you to be 21.12Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Questions and Answers Some calibers work in both platforms. The classic example is .22 LR. For dual-use ammunition, the dealer is supposed to determine your intended use, but many stores simply refuse to sell any dual-use caliber to anyone under 21 as a liability policy.
Federal Disqualifications That Override Everything
Even if you got the gun through a legal gift or inheritance, federal law separately bars certain people from possessing firearms at all. These apply regardless of age:
- Current users of any controlled substance, including marijuana. A state medical marijuana card does not change this.
- Anyone convicted of a misdemeanor crime of domestic violence. The ban is permanent.
- Anyone subject to an active court order restraining them from harassing or threatening an intimate partner or that partner’s child.
- Anyone convicted of a crime punishable by more than one year in prison, whether or not they actually served time.
- Anyone formally adjudicated as mentally defective or involuntarily committed to a mental institution.
The marijuana rule catches more young adults than any other. State legalization has no effect on the federal prohibition, so a Florida medical cannabis patient who accepts a gifted firearm is still a prohibited person under federal law.3Bureau of Alcohol, Tobacco, Firearms and Explosives.

What About the Reese Decision?
You may have read that a federal appeals court struck down the age restriction on handgun purchases. In January 2025, the U.S. Court of Appeals for the Fifth Circuit ruled in Reese v. Bureau of Alcohol, Tobacco, Firearms, and Explosives that the federal ban on dealers selling handguns to 18-to-20-year-olds violates the Second Amendment.13U.S. Court of Appeals for the Fifth Circuit. Reese v. Bureau of Alcohol, Tobacco, Firearms, and Explosives – Opinion That decision binds only Texas, Louisiana, and Mississippi. It does not change Florida law. Any 18-year-old who walks into a Florida gun store today will still be turned away.
