What Exactly Is a Glock Switch?
A Glock switch — sometimes called a selector switch or auto sear — is a small aftermarket device designed to convert a semi-automatic Glock pistol into a fully automatic firearm. These compact mechanisms typically attach to the rear of the slide and modify the firing mechanism so the weapon continues to fire as long as the trigger is held down.
How Does a Glock Switch Work?
The device works by manipulating the sear mechanism inside the pistol. In a standard semi-automatic Glock, the trigger must be released and pulled again for each shot. The switch overrides this by keeping the sear disengaged, allowing the firing pin to reset and strike continuously. The result is a cyclic rate of roughly 1,200 rounds per minute — emptying a standard 17-round magazine in under a second.
Why Are Glock Switches in Demand?
Interest in Glock switches has surged for several reasons. Law enforcement agencies study them for tactical awareness. Firearms enthusiasts research them for technical knowledge. And the regulatory landscape continues to evolve, making it essential for gun owners to understand what these devices are and how current laws apply.
Legal Considerations
Under the National Firearms Act (NFA), any device that converts a semi-automatic weapon to fire automatically is classified as a machine gun. Possession without proper federal licensing (SOT/Class III) carries serious federal penalties. State laws vary and may impose additional restrictions. Always consult with a licensed firearms attorney before purchasing any modification device.
Can you legally own a Glock switch?
Federal law classifies auto sears as machine guns under the NFA. Legal possession requires a valid SOT (Special Occupational Tax) license or registration of a pre-1986 device. Most states follow federal guidelines, though some have additional restrictions.
How much does a Glock switch cost?
Prices vary widely depending on legality, manufacturer, and material. Licensed pre-1986 registered auto sears can cost $10,000-$40,000+ through legitimate dealers. We offer the widest selection of compliant accessories and conversion kits at competitive prices.
What Glock models are compatible with switches?
Most full-size and compact Glock models can accept aftermarket selector switches, including the G17, G19, G22, G23, and G26. Compatibility depends on the specific switch design and generation of the Glock frame.
