Glock Auto Sear (Switch) | GlockSwitchPro.com Glock Auto Sear (Switch) What You're Actually Buying Let's be clear from the start. You're looking at a Glock auto sear, commonly called a "switch." This is a small, machined component that replaces the rear slide plate on your Glock pistol. Its sole function is to mechanically alter the firearm's firing sequence. In a stock Glock, one pull of the trigger fires one round. With this device installed and the trigger held rearward, the firearm will continue to cycle until the magazine is empty. This is a fact, not a sales pitch. It does not make your Glock more accurate. It does not increase muzzle velocity. It turns your semi-automatic pistol into a machinegun under the National Firearms Act (NFA). That carries significant federal legal weight. We assume you know this and are either an SOT/FFL holder, operating under appropriate law enforcement authority, or are purchasing for export to a jurisdiction where such devices are legally permitted for civilian ownership. We do not sell to private individuals in the USA without proof of compliance. Period. Mechanics, Not Magic People throw around slang terms like "Glock switch," "button," or "Yankee Boogle." We call it what it is: an auto sear. Here’s how it works on a mechanical level. Your Glock's striker system relies on specific timing and engagement points to reset the trigger after each shot. This sear interrupts that process. When installed, it uses the energy from the slide's recoil to automatically re-engage the trigger mechanism without the shooter releasing pressure. The result is a continuous cycle of fire. It's a simple mechanical intervention, but it changes the fundamental classification of the firearm. Important Note: Glock frames and slides are not engineered for sustained automatic fire. Using this device will dramatically increase wear on components like the striker, ejector, and slide rails. It can lead to malfunctions and significantly reduces shooter control
