What is a Glock switch?
A Glock switch, often called an auto sear or selector switch, is a small aftermarket device that modifies a semi-automatic Glock pistol to fire in a fully automatic mode. It’s a metal or polymer component that replaces the rear plate on the slide.
Are Glock switches legal?
No. Under federal law, a Glock switch is classified as a machinegun and is regulated by the National Firearms Act (NFA). Possession without the proper tax stamp, registration, and approval from the ATF is a serious felony. You can read more on the legal specifics in our complete legal guide to Glock switches.
How much does a legal auto sear cost?
For a legally registered, transferable machinegun sear that works with a Glock, prices start around $10,000 and go up significantly from there due to the limited supply. The device itself is cheap; the legal registration is what carries the extreme cost.
Can I buy a Glock switch online?
You cannot legally purchase an unregistered switch online. Any site offering them for direct sale is almost certainly a scam or a law enforcement sting. For legal firearm accessories, always use a reputable dealer like the Kentucky Gun Shop.
What’s the difference between a switch and a binary trigger?
A true Glock switch creates fully automatic fire. A binary trigger is a legal alternative that fires one round on the pull and one on the release of the trigger. They are fundamentally different in function and legality. We break down the pros and cons in our detailed switch vs. binary trigger comparison.
Which Glock models are compatible?
Most common models like the Glock 17, 19, 26, and their .40 cal and .45 cal counterparts (like the 21) are compatible, as they share the same rear plate design. It generally does not work on slimline models like the G43 or the new G47.
How is a Glock switch installed?
Installation is mechanically simple: you remove the factory rear slide plate and replace it with the switch unit. The legal and functional process of properly registering and installing one into a host firearm, however, requires an FFL/SOT with the correct licensing.
Does using a switch damage my Glock?
Yes, dramatically. Full-auto fire generates immense heat and stress. You’ll experience accelerated wear on the slide, barrel, recoil spring assembly, and locking block. It’s brutal on a pistol not designed for sustained automatic fire.
How reliable is a Glock switch?
Cheap, illicit switches are notoriously unreliable and can cause out-of-battery detonations. Even properly made units increase the likelihood of malfunctions like hammer follows or failures to feed due to the extreme cyclic rate.
What’s the rate of fire with a switch?
It’s extremely high, typically around 1,200 to 1,500 rounds per minute. That’s about 20-25 rounds per second. A standard 17-round magazine empties in less than one second, making it highly uncontrollable without extensive training.
Can you ship a Glock switch to my house?
A legally registered NFA item like a machinegun sear must be shipped to a holder of a Federal Firearms License (FFL), specifically one with a Special Occupational Tax (SOT) status for NFA items. Direct-to-doorstep shipping for these is not legal.
Are there any legal alternatives?
Yes. For increased firepower, consider a binary trigger system or a pistol-caliber carbine. For rapid shooting practice, invest in a high-quality trigger upgrade or recoil management accessory from our catalog.
How do I maintain a firearm with an auto sear?
Maintenance becomes critical. You must clean and inspect the firearm after every use, paying close attention to carbon buildup and metal fatigue. Recoil springs become a frequent replacement item, akin to a consumable part.
Why are they sometimes called “Glock chips”?
It’s slang derived from their small size, often resembling a USB drive or a small “chip” of metal. The term is used interchangeably with “switch” in some circles, but it refers to the same illegal conversion device.
