Sawed-off shotguns are illegal to own or possess in Florida unless the weapon is registered with the federal Bureau of Alcohol, Tobacco, Firearms and Explosives under the National Firearms Act. Unregistered possession is a second-degree felony, punishable by up to 15 years in state prison and a $10,000 fine, and the same conduct can also be charged federally. A separate category of pistol-grip shotshell firearms, like the Mossberg Shockwave, is not legally a “shotgun” at all and sits outside this ban.
What Florida Counts as a Sawed-Off Shotgun
Florida Statute Section 790.001(17) defines a short-barreled shotgun as any shotgun with one or more barrels shorter than 18 inches, or any weapon made from a shotgun that has been altered to an overall length under 26 inches.1Florida Senate. Florida Code 790.001 – Definitions Failing either measurement is enough. A shotgun with a 16-inch barrel and a 28-inch overall length qualifies because the barrel is too short. A shotgun with an 18-inch barrel modified to a 24-inch overall length also qualifies because the total length is too short.
It doesn’t matter whether the weapon left the factory this way or someone cut it down in a garage. The moment a modification drops the dimensions below either limit, the weapon’s legal classification changes. Florida’s definition mirrors the federal National Firearms Act, which uses the same 18-inch and 26-inch thresholds.
The Possession Ban and Its Narrow Exceptions
Florida Statute Section 790.221(1) makes it unlawful for any person to own or possess a short-barreled shotgun that is operable or could readily be made operable.2Florida Senate. Florida Code 790.221 – Possession of Short-Barreled Rifle, Short-Barreled Shotgun, or Machine Gun; Penalty “Possess” is broader than physically holding the weapon. A sawed-off shotgun stored in your home, vehicle, or anywhere else under your control counts, and Florida courts recognize constructive possession, so charges can follow even if you never touched the gun, as long as you knew about it and could access it.
The statute carves out two exceptions. Antique firearms are exempt, meaning weapons manufactured in or before 1918, replicas of pre-1918 designs, or firearms that use fixed ammunition no longer commercially produced in the United States.1Florida Senate. Florida Code 790.001 – Definitions The second exception covers short-barreled shotguns that are lawfully owned under federal law.2Florida Senate. Florida Code 790.221 – Possession of Short-Barreled Rifle, Short-Barreled Shotgun, or Machine Gun; Penalty That second exception is the entire legal pathway for owning one.
How to Own One Legally
The only practical way to lawfully possess a sawed-off shotgun in Florida is to register it with the ATF under the National Firearms Act. Until recently, this meant paying a $200 federal excise tax and receiving a tax stamp. Effective January 1, 2026, Congress eliminated the $200 tax for short-barreled shotguns, short-barreled rifles, and suppressors through the One Big Beautiful Bill Act. The tax still applies to machine guns and destructive devices. For a short-barreled shotgun, the financial cost of federal registration is now zero.
Registration itself hasn’t changed. You submit an application to the ATF, pass a background check, and wait for approval before taking possession. Which form you file depends on the situation:
- ATF Form 4 is used when you’re buying or receiving a short-barreled shotgun that already exists. A licensed dealer usually handles most of the paperwork.
- ATF Form 1 is used when you’re building one, typically by cutting down an existing shotgun barrel. ATF approval must come before any modification.
Both forms require fingerprints and a photograph, and both can be filed as an individual, through a trust, or through a corporation. Filing a Form 1 and cutting the barrel before approval arrives is a federal crime, even if you fully intend to register the weapon. The ATF does not grandfather retroactive applications.
Registering Through a Gun Trust
Many Florida owners register sawed-off shotguns through a gun trust rather than as individuals. The trust becomes the legal owner, and any named trustee can possess and use the weapon without the registered individual present. This avoids a common problem: if you register as an individual and your spouse or roommate has unsupervised access, that person could face a possession charge because they aren’t the registered owner. Every trustee must submit fingerprints, a photograph, and pass a background check when the trust applies for a new NFA item, and every trustee must remain legally eligible to possess firearms.
Penalties for Unregistered Possession
Florida treats possession of an unregistered sawed-off shotgun as a second-degree felony.2Florida Senate. Florida Code 790.221 – Possession of Short-Barreled Rifle, Short-Barreled Shotgun, or Machine Gun; Penalty A conviction carries up to 15 years in state prison3The Florida Legislature. Florida Code 775.082 – Penalties; Applicability of Sentencing Structures; Mandatory Minimum Sentences for Certain Reoffenders Previously Released From Prison and fines up to $10,000, plus court costs and other fees on top.4The Florida Legislature. Florida Code 775.083 – Fines Probation often follows, with restrictions on travel, employment, and housing for years after release.
Federal penalties stack on top. Possessing an unregistered NFA firearm violates 26 U.S.C. ยง 5861, which carries up to 10 years in federal prison and a fine of up to $250,000.5Office of the Law Revision Counsel. 26 USC 5871 – Penalties State and federal prosecutors can charge the same conduct independently, so a single unregistered sawed-off shotgun can produce both cases. Federal prosecutors regularly pursue NFA violations, particularly when the weapon turns up during a search tied to other offenses.
Pistol-Grip Shotshell Firearms Are a Different Category
Firearms like the Mossberg Shockwave and Remington Tac-14 have 14-inch barrels and fire shotgun shells, yet they sell legally across Florida without NFA registration. The reason sits in a single word in the definition: “shotgun.” Under both federal and Florida law, a shotgun must be designed or intended to be fired from the shoulder.1Florida Senate. Florida Code 790.001 – Definitions The Shockwave and similar firearms ship from the factory with a pistol grip and no shoulder stock, so they were never designed to be shouldered and never met the legal definition of a shotgun. If the weapon isn’t a shotgun, it can’t be a “short-barreled shotgun.” The ATF classifies these as plain “firearms,” a catch-all category that doesn’t trigger NFA restrictions, provided the overall length stays at 26 inches or above.
Factory configuration is what matters. If you buy a standard pump-action shotgun with a shoulder stock, swap the stock for a pistol grip, and cut the barrel to 14 inches, you’ve created an NFA weapon, because that firearm was originally manufactured as a shotgun. The Shockwave sidesteps this by never having been a shotgun to begin with. The legal distinction turns on the weapon’s original design, not its current appearance.
Bringing a Registered One Across State Lines
Federal law requires prior ATF authorization before transporting a short-barreled shotgun across state lines.6Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts You cannot simply pack a registered sawed-off shotgun in your truck and drive to Georgia for the weekend. You file ATF Form 5320.20 specifying the firearm, destination, and dates of travel, and you need written approval before moving it.7Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Transport Interstate or to Temporarily Export Certain National Firearms Act (NFA) Firearms The approval covers only the dates listed.
Moving to Florida permanently with a registered sawed-off shotgun also requires a Form 5320.20, filed with “change of address” as the reason. Arriving in Florida with a properly registered weapon and current ATF paperwork satisfies the state exception under 790.221(3). Arriving without the paperwork means committing a second-degree felony the moment you cross the state line.
Firearm Rights After a Felony Conviction
A second-degree felony conviction in Florida does more than prison time and fines. It strips your right to own or possess any firearm, not just sawed-off shotguns. Federal law separately prohibits anyone convicted of a felony from possessing firearms or ammunition, with a penalty of up to 10 years in federal prison for violations.8Middle District of Florida. Felony Offenders Restoration in Florida runs through the Office of Executive Clemency and cannot even be applied for until eight years after completing a sentence and supervision, with separate state and federal tracks and no guaranteed outcome. For anyone considering cutting down a barrel without going through the NFA process, the permanent loss of all firearm rights is often the steepest cost of getting it wrong.
