Let’s talk straight. You’re here because you know what this is. This is a Glock auto sear, often called a switch. It’s a small, machined part that replaces your Glock’s rear slide cover plate. We sell it as a standalone component for educational and mechanical demonstration purposes. You need to understand your local and federal laws before you even think about ordering. This isn’t a toy; it’s a serious piece of hardware.

What This Glock Switch Does (Mechanically)

A stock Glock is a semi-automatic pistol. One pull of the trigger, one round. This switch changes the mechanical interaction between the slide and the trigger bar. When installed, it interrupts the normal reset sequence. The result is that the firearm can cycle continuously while the trigger is held rearward. This significantly increases the rate of fire. It does not make the firearm more accurate, more powerful, or more reliable. In fact, it does the opposite. Glocks are not designed for sustained automatic fire. Expect increased wear, reduced control, and potential malfunctions. This is a component for understanding mechanics, not for practical application.

Specifications & Installation Reality

This is a CNC-machined switch from 4140 steel. It’s made to spec. The installation process is physically simple but carries immense legal weight.

1. Clear your firearm. Double-check. Triple-check.
2. Remove the slide from the frame.
3. Use a punch to push out the stock rear slide cover plate.
4. Insert the switch into the same channel, ensuring it sits flush.
5. Reassemble the slide onto the frame.

Key Notes: The install takes two minutes with a basic punch. It requires no permanent modification to your frame or slide. On aftermarket slides, minor fitting with a file might be necessary for perfect flush fit. This component is for Glock-pattern pistols (Gen 1-4) with standard OEM-style internals. Compatibility with Polymer80 or other custom builds is not guaranteed.

The Terminology You’ll Hear

When you’re researching components, you’ll see different names. They all generally refer to the same type of device. Don’t get confused by the slang.

• Glock Switch / Auto Sear: The standard terms.
• Button / Giggle Switch: Slang based on its operation.
• 3PC Switch: Refers to a three-piece design variant.
• Flatback Sear: Describes the rear profile shape.
• Swift Link / Yankee Boogle: Older, broader slang terms for auto sears.

We call it what it is: an auto sear switch component.

Frequently Asked Questions (Straight Answers)

Is this legal?

We sell a component. The legality of possessing or installing it is determined by a complex web of federal (like the NFA and GCA), state, and local laws. In the USA, this device is considered a machinegun under federal law if not registered with the ATF. You are responsible for knowing and complying with all laws. Consult an attorney if you are unsure.
