Under Florida law, does attaching a stabilizing brace to a pistol turn it into a 'short-barreled rifle'?

Plain-English summary

Florida Attorney General Ashley Moody concluded that a pistol with a stabilizing brace is not a "short-barreled rifle" under Florida law, even though the federal ATF had announced a rule treating most braced pistols as subject to National Firearms Act controls.

Florida's definition of "short-barreled rifle" in § 790.001(11), Fla. Stat. requires a rifle — a weapon with a rifled bore designed to be fired from the shoulder — with a barrel under 16 inches or overall length under 26 inches. A handgun is defined separately in chapter 790 as a firearm capable of being carried and used with one hand. The two categories are mutually exclusive, distinguished by the firearm's fundamental design.

A stabilizing brace is an optional accessory that lets a shooter fire a handgun from the shoulder if desired. The AG concluded that attaching one doesn't change the underlying weapon's essential nature: it remains a handgun, not a rifle.

This opinion explicitly addresses only Florida law and does not override federal ATF regulations.

What this means for you

If you own a pistol with a stabilizing brace in Florida

Under Florida law (chapter 790), you do not possess a "short-barreled rifle" simply by attaching a stabilizing brace. The state-law prohibition in § 790.221 on owning, having, or possessing a short-barreled rifle does not apply to your braced pistol.

Important caveat: This opinion does not affect federal law. ATF rules under the National Firearms Act may treat your braced pistol as a regulated firearm. You can be in compliance with Florida law and out of compliance with federal law at the same time. Consult a federal-firearms attorney if you have a braced pistol.

If you're a Florida sheriff, deputy, or local officer

Do not charge possession of a braced pistol as possession of a short-barreled rifle under § 790.221. The Florida AG has interpreted the state definition to exclude braced pistols. Federal violations are a federal-officer matter.

If you're a Florida firearms dealer (FFL)

Florida's chapter 790 does not require you to treat braced pistols as short-barreled rifles. State sales records and customer disclosures should track Florida's definitions; federal disclosures are a separate matter governed by ATF rules.

If you're a Florida legislator

The AG explicitly invites legislative clarification: "unless and until judicially or legislatively clarified." If you want Florida law to follow ATF's classification (or to expressly diverge), you'd need to amend § 790.001(11) to address brace attachments.

Common questions

Q: Does this opinion override the federal ATF rule?
A: No. The opinion explicitly addresses only Florida law and "does not address the federal government's rule or the policy on which it based the rule." Federal law is supreme on federal-firearms questions.

Q: What's a stabilizing brace?
A: It's an attachment to the rear of a firearm that lets the shooter brace it against the shoulder. It was originally designed to help disabled shooters fire handguns one-handed.

Q: Why isn't a braced pistol a short-barreled rifle under Florida law?
A: Because the Florida definition requires the weapon to be a rifle — a weapon with a rifled bore designed to be fired from the shoulder. A handgun is structurally different: it's designed to be fired with one hand. Adding an optional accessory that enables shoulder-firing doesn't change the underlying design.

Q: Could a Florida court reach a different conclusion?
A: Yes — AG opinions are persuasive but not binding. The AG explicitly notes the conclusion holds "unless and until judicially or legislatively clarified." A court could reinterpret § 790.001(11), but the textual argument here is strong.

Q: What if the brace is permanently attached and used solely as a shoulder stock?
A: The opinion doesn't address all use-cases. It says using a brace doesn't change the "fundamental characteristics" of the handgun, but a configuration so altered that it's effectively a rifle from the start might be analyzed differently. Most braced pistols on the market remain handguns under this analysis.

Background and statutory framework

Article I, § 8(a) of the Florida Constitution affirms the right to keep and bear arms, "except that the manner of bearing arms may be regulated by law." Chapter 790 is the Legislature's exercise of that regulatory power.

§ 790.001(11), Fla. Stat. defines "short-barreled rifle":

"a rifle having one or more barrels less than 16 inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon as modified has an overall length of less than 26 inches."

§ 790.221 makes possession of such a rifle unlawful. Both statutes were enacted in 1969.

The AG's reasoning relies on:
1. Plain-meaning textualism. A "rifle" is a weapon with a rifled bore intended to be fired from the shoulder. A "handgun" is one that can be carried and used with one hand. Two distinct definitions, two distinct categories.
2. Mutually-exclusive scheme. § 790.221 prohibits short-barreled rifles; handguns are regulated separately and not subject to that prohibition. The Legislature treated them as different things.
3. Florida case law. The Second DCA emphasized the narrow "integral, operable rifle" character. Florida v. Weeks (Fla. Sup. Ct.) held that firearm classification turns on the firearm's distinctive operational features — here, the firing system and shooting posture.

The Bureau of Alcohol, Tobacco, Firearms and Explosives published "Factoring Criteria for Firearms with Attached 'Stabilizing Braces,'" 88 Fed. Reg. 6,478 (Jan. 31, 2023), proposing to treat ~99% of braced pistols as short-barreled rifles under federal law. This Florida AG opinion responds only to whether Florida's definition tracks the federal interpretation — concluding it does not.

Representative Shane Abbott
Florida House of Representatives
908 US Highway 90 West
NWFSC Chautauqua Center
DeFuniak Springs, FL 32433-1436

Dear Representative Abbott:

This office received your letter, dated March 21, 2023, requesting a legal opinion pursuant to Section 16.01(3), Florida Statutes. You ask substantially the following question:

Does the definition of "short-barreled rifle" codified at section 790.001(11), Florida Statutes (2022), include a pistol with a stabilizing brace?

In sum

Unless and until judicially or legislatively clarified, I conclude that the definition of "short-barreled rifle," which the Legislature enacted in 1969, does not include a handgun, such as a pistol, to which a person attaches a stabilizing brace, because the use of such an optional accessory does not change the fundamental characteristics of the handgun.

Background

In your letter, you describe a recent rule the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) proposed, in which it set forth "factoring criteria" to "clarify" how it intends to determine whether a firearm's configuration would be subject to certain regulations. You state that ATF estimates that, under the new rule, "99% of pistols equipped with stabilizing braces will now be deemed subject to National Firearms Act controls." You raise both policy and legal concerns regarding the ATF's rule.

Although the ATF's proposed rule and other statements of the federal government concerning specific firearms prompted your request, I understand that your request specifically seeks an opinion concerning the definition of "short-barreled rifle," as codified in section 790.001(11), Florida Statutes (2022). As such, this opinion does not address the federal government's rule or the policy on which it based the rule, but instead analyzes the meaning of "short-barreled rifle" under Florida law.

Analysis

The Legislature based the various provisions of chapter 790 ("Weapons and Firearms") on Article 1, section 8(a) of the Florida Constitution, which states, in part, that "the right of the people to keep and bear arms in defense of themselves and of the lawful authority of the state shall not be infringed, except that the manner of bearing arms may be regulated by law." Based on this provision, the Legislature defined "short-barreled rifle" as "a rifle having one or more barrels less than 16 inches in length and any weapon made from a rifle (whether by alteration, modification, or otherwise) if such weapon as modified has an overall length of less than 26 inches." The Legislature then declared it "unlawful for any person to own or have in his or her care, custody, possession, or control any short-barreled rifle … which is, or may readily be made, operable."

When interpreting a statute, courts first consider the entire text of the statute and analyze its plain meaning. Courts consider statutory provisions together when such provisions are part of the same statutory scheme. When necessary, the plain and ordinary meaning of words can be ascertained by reference to a dictionary.

Both the plain language of the terms "short-barreled rifle" and "handgun" and consideration of the terms in pari materia with other terms and provisions of chapter 790 lead to the conclusion that chapter 790 regards a rifle as fundamentally distinct from a handgun, such as a pistol or revolver. A rifle refers to a firearm that has a rifled bore and is intended to be fired from the shoulder. In contrast, the Legislature recently defined "handgun" to mean "a firearm capable of being carried and used by one hand, such as a pistol or revolver."

The definition of "short-barreled rifle" includes a measurement for the maximum length of the barrel and overall length of the firearm; however, the Legislature broadly defined "handgun" as any firearm that can be carried or used with one hand, regardless of the length of its barrel. The distinction between the two definitions—one of which contains specific measurements and the other of which describes the manner of use—indicates the Legislature regards the terms as mutually exclusive. Analysis of the provisions of chapter 790 verifies that the two terms are not interchangeable: section 790.221, as noted above, prohibits the care, custody, possession, or control any short-barreled rifle; in contrast, a handgun is not prohibited, but the Legislature has established various provisions applicable to its use.

A stabilizing brace is an attachment that, when added as designed to the rear of a firearm, enables a person to fire the firearm from his or her shoulder. Attaching a stabilizing brace to a handgun only affects the manner of use in which the person using the firearm will engage: it does not affect the structural characteristics or integral nature of the handgun as commonly understood. Concluding that the addition of a stabilizing brace to a handgun would alter the fundamental characteristics of the handgun to the extent that it must be recategorized would ignore the purpose for use of a brace, as a brace can only be used with a handgun because it exists to enable a person to continue to use the handgun as the definition contemplates: with one hand. A person's choice to use a brace does not change the fundamental nature of the firearm with which the person uses it; rather, using a brace simply enables a person to hold the handgun with one hand.

Furthermore, concluding that the attachment of a brace results in recategorizing the firearm would disregard the Legislature's clear intent to define "short-barreled rifle" in a specific manner. The Second District Court of Appeal emphasized the specificity of the definition of "short-barreled rifle," and the narrow nature of considering a type of firearm as such a rifle, by holding that the definition does not contemplate "another type of weapon" such as a "common handgun" made "from rifle parts." The court stated that the definition refers to "a weapon which in its essence is an integral, operable rifle, as the term rifle is commonly understood … whether from the shoulder or as a common hand gun." Concluding that a handgun could become a short-barreled rifle by attaching a stabilizing brace would cause us to disregard the essence a rifle, which, in its "integral, operable" form, means a firearm with a rifled bore that is generally fired from a person's shoulder.

This analysis is also consistent with the Supreme Court of Florida's analytical model in Florida v. Weeks, in which the court concluded that determining whether a firearm was a "replica" of an "antique firearm" under section 790.001 depends on the characteristics and functioning of the type of firing system. The court emphasized that understanding the firing system was critical because the system is the distinctive feature of the firearm. In this regard, the court's analysis is consistent with the Second District Court of Appeal's focus on the integral, operable nature of the firearm as being critical to determining its essence. Here, the distinctive features of the essence of a handgun and a short-barreled rifle are simple: a handgun, by definition, can be fired with only one hand and, in contrast, a rifle is designed with the intention that a person will fire it from his or her shoulder, due to the length of its stock. Opting to use a stabilizing brace with a handgun does not change its fundamental characteristics.

Conclusion

Based on the foregoing, unless and until judicially or legislatively clarified, I conclude that neither section 790.001 nor section 790.221, Florida Statutes, prohibit a person from using a handgun with a stabilizing brace. The various definitions of distinct types of firearms codified at section 790.001, Florida Statutes, are based on the fundamental design and operational characteristics of each firearm. Therefore, attaching such a brace does not result in a redesign of the firearm and does not result in a different type of functionality of the firearm; instead, it only assists with the use of the firearm.

Sincerely,

Ashley Moody
Attorney General
