What Is the Glock Switch Act?
In 2022, the ATF logged over 5,000 recovered conversion devices, a 570% increase from 2017. That statistic is the direct reason Congress passed the “Glock Switch Act,” formally known as Section 932 of the 2022 National Defense Authorization Act. This law didn’t just increase penalties; it fundamentally changed the legal landscape for anyone manufacturing, selling, or possessing a forced reset trigger (FRT) or auto-sear for a pistol. If you own or are considering any aftermarket trigger modification, you need to understand this act. It’s not bureaucratic noise—it’s the rulebook.
The Core Provision: Redefining a “Machinegun”
The Glock Switch Act’s primary action was to amend the definition of a “machinegun” under the National Firearms Act (26 U.S.C. 5845(b)). The new language explicitly includes “a combination of parts designed and intended for use in converting a weapon into a machinegun” and “any part or combination of parts designed and intended solely and exclusively for use in converting a weapon into a machinegun.” This technical wording is a direct shot at forced reset triggers and auto-sears. Prior to this, the ATF had to argue that these devices themselves met the mechanical definition of a machinegun. Now, the law states that any part intended to facilitate conversion is, in itself, a machinegun. This gives the ATF significantly broader authority for enforcement and prosecution.
Penalties: From Misdemeanor to Felony
Before this act, illegal possession of an unregistered machinegun was a felony, but the illegal manufacture or sale of conversion devices was often treated as a misdemeanor under the Gun Control Act. The Glock Switch Act changed that calculus entirely. It established new, severe criminal penalties. Now, anyone who “knowingly” manufactures, sells, or possesses a conversion device is subject to a fine and up to 10 years in prison. For context, that’s a stiffer potential sentence than for many firearms trafficking offenses. This isn’t a slap on the wrist; it’s a decade in federal prison. The act also mandates that the U.S. Sentencing Commission review and amend its guidelines to reflect the seriousness of these new offenses.
Impact on the Market and Enthusiasts
The immediate impact was the cessation of commercial sales for products like the Rare Breed FRT-15 trigger and various “Glock switch” auto-sears from domestic retailers. Overnight, legally recognized products became contraband. For enthusiasts, the line between a legal performance trigger and an illegal machinegun conversion device became razor-thin and defined entirely by ATF classification letters, which are subject to change. This created significant confusion and risk. It also pushed the conversation entirely into the realm of pre-1986 registered dealer samples and law enforcement/military contracts. For a civilian, sourcing a legal, registered auto-sear for a Glock now involves navigating the NFA process with a transferable receiver or registered sear, which can cost upwards of $10,000.
Legal Distinctions and Current Reality
It’s critical to understand what the act does not do. It does not ban all aftermarket triggers. A standard drop-in connector or a flat-faced trigger shoe from a reputable manufacturer like Glockstore, provided it doesn’t alter the rate of fire beyond the standard semi-automatic function, remains legal. The act targets devices whose sole, intended purpose is to mimic automatic fire. The current reality is that the ATF’s Firearms Technology Division aggressively examines any trigger mechanism that appears to “function as a machinegun.” If you’re modifying your firearm, your first stop should be verifying the current ATF classification of that specific product.

FAQ
What is the Glock Switch Act?
The Glock Switch Act is the common name for Section 932 of the 2022 National Defense Authorization Act. It is a federal law that broadened the legal definition of a “machinegun” to explicitly include parts, like auto-sears or forced reset triggers, designed to convert a semi-automatic firearm into an automatic one. It also established felony penalties of up to 10 years in prison for manufacturing, selling, or possessing such devices.
What does a Glock switch actually do?
A Glock switch, technically an auto-sear or selector switch, is a small metal or polymer device that replaces the rear plate on a Glock pistol’s slide. When installed, it mechanically holds the disconnector down, allowing the firearm to fire continuously with a single pull of the trigger until the magazine is empty, converting it from semi-automatic to fully automatic fire.
