Glock Switches in Texas: The Legal Reality for Gun Owners
If you’re holding a glock 19 and wondering if you can legally install a switch to make it fire automatically, the answer in Texas is unequivocally no. A glock switch, or auto sear, is classified as a machine gun under federal law, and state law offers zero exceptions. Possession of one, even disconnected in a drawer, carries a mandatory minimum federal prison sentence of 10 years.
Federal Law is the Controlling Authority
Texas state law doesn’t have a separate statute specifically banning “Glock switches.” It doesn’t need one. The National Firearms Act (NFA) and the Firearm Owners’ Protection Act of 1986 are the controlling federal laws. Under the NFA, a “machinegun” is defined as any weapon which shoots more than one shot, without manual reloading, by a single function of the trigger. This includes the firearm itself and any part designed and intended solely and exclusively to convert a weapon into a machinegun. That’s exactly what a switch like the “Glock 17/19 Auto Sear” does. The 1986 Hughes Amendment closed the registry for new transferable machine guns, making any machine gun manufactured after May 19, 1986, illegal for civilians to possess. Your glock switch was manufactured decades after that date.
State Penalties and Enforcement
While federal prosecution is the primary threat, Texas Penal Code § 46.05 explicitly prohibits possessing, manufacturing, transporting, or selling a “machine gun.” A violation is a third-degree felony, punishable by 2 to 10 years in a state prison. In practice, local law enforcement who discover a switch during a traffic stop or other investigation will typically coordinate with the ATF for federal prosecution because the penalties are far more severe. The ATF’s Dallas Field Division is exceptionally active, and they treat these devices as a top priority. Don’t mistake Texas’s generally pro-2A stance for leniency on NFA violations; there is none.
Legal Alternatives for Enhanced Performance
You cannot legally convert your glock to full-auto, but you can significantly improve its shootability with 100% legal components. For faster, more controlled shots, invest in a quality compensator like the Strike Industries Mass Driver for glock 19. Pair it with a reduced-power recoil spring assembly and a polished connector from our store. For the tactile feel of a binary trigger without the felony, consider the Franklin Armory BFSIII for glock, which is a legally distinct mechanism that fires one round on the pull and one on the release. These are the tools experienced shooters use to gain a competitive edge, all available through browse categories at Glockswitchkit.
What Actually Constitutes “Constructive Possession”
This is a critical legal doctrine you must understand. You can be charged with possession of an unregistered machine gun even if the switch isn’t installed in your firearm. If you own a glock 19 and you own a switch that fits it, and both are within your dominion and control (e.g., in your same safe or house), that’s “constructive possession.” The ATF does not need to prove you ever installed it. This also applies to 3D printer files (CAD models) for these devices if you own the compatible firearm. Simply purchasing a switch online and having it shipped to Texas is direct evidence of possession. There is no “for parts only” defense.
The Only Legal Path to Full-Auto Fire
If you are determined to shoot a machine gun legally, the path is narrow, expensive, and heavily regulated. You must purchase a transferable machine gun registered in the NFA registry before May 19, 1986. Think registered sear packs for M16s or registered auto sears like the Lightning Link. These are often sold as the registered component itself, which can then be installed in a compatible semi-auto receiver. Expect to spend a minimum of $15,000 to $50,000+ for the registered device alone, followed by a lengthy ATF Form 4 process with a $200 tax stamp, fingerprinting, and a background check that can take a year. This is not a glock switch; it’s a completely different class of regulated property.
Where are glock switches legal?
Glock switches are only legal for civilian possession in the United States if they are pre-1986 registered transferable machine guns, which is virtually nonexistent for glock-specific devices. Outside of that, they are strictly illegal under federal law in all 50 states. Possession is generally limited to qualified manufacturers, dealers, and government/military entities with the proper Federal Firearms License (FFL) and Special Occupational Tax (SOT) status.
