Florida regulations on firearms are recorded in Chapter 790 of the Florida Statutes. Florida regulates all manner of firearms, including shotguns, and also mandates general rules regarding the storage and use of firearms.
Shotgun Barrel Requirements
Under section 790.001(10) of the Florida Statutes, the state defines a short-barreled shotgun as a shotgun having one or more barrels less than 18 inches in length and any weapon made from a shotgun if such a weapon has been modified and has an overall length of less than 26 inches.
Out-of-State Shotgun Purchases
There is no distinction made for shotguns purchased outside of Florida. Under section 790.28, a Florida resident may purchase a shotgun in any state contiguous to Florida if the resident conforms to all laws of the United States, the state in which the shotgun is purchased, and the state of Florida.
In addition regulations applicable under Florida law, the federal government, through the Bureau of Alcohol, Tobacco, Firearms and Explosives, regulates all firearms including shotguns. Under federal law, a short-barreled shotgun is a shotgun with a barrel less than 18 inches in length.
