Ever wondered what it feels like to transform your everyday Glock 19 into a full-auto powerhouse? The answer lies in one compact, game-changing upgrade — the Glock 19 switch.
This small but powerful device has become a hot topic among firearm enthusiasts, collectors, and tactical operators. But beyond the buzz, what exactly does a Glock 19 switch do, and why is it making waves in the shooting community?

What Is a Glock 19 Switch and Why Does It Matter?
The Glock19 switch, also known as a full-auto sear or auto switch, is a conversion device designed to turn a semi-automatic Glock 19 into a fully automatic handgun.
That means with a single pull of the trigger, your Glock 19 can discharge rounds in rapid succession — like a submachine gun in the palm of your hand.
Why does this matter? For professionals, trainers, and legal FFL owners, this upgrade offers a massive edge in tactical efficiency, training simulations, and collection value.
The First Time I Fired a Glock19 Switch-Equipped Handgun
I still remember the first time I test-fired a Glock 19 with a legal, ATF-compliant switch. The roar of the first burst, the unmistakable vibration of full-auto fire, and the tight groupings on the target completely changed the way I viewed handguns.
What amazed me most wasn’t just the firepower — it was the control. When properly installed and paired with the right accessories, a Glock19 switch makes for a high-performance platform that remains accurate, agile, and deadly efficient.
How Does a Glock19 Switch Work?
Mechanically speaking, the switch alters the firing mechanism inside your Glock 19 by changing how the trigger assembly resets. Instead of resetting after each shot (semi-auto), the mechanism allows the slide to continue firing as long as the trigger is held down.
Here’s a simplified breakdown:
- The switch fits onto the backplate of your Glock 19.
- It interfaces with the slide and trigger bar.
- When engaged, it removes the disconnector function — allowing continuous firing.
