Advantage Arms Conversion Kit for Glock Gen 4 19/23 - 22LR, 4.02" Barrel

The Advantage Arms conversion kit for Glock Gen 4 19/23 turns your everyday carry or duty pistol into a nimble .22 LR shooter—perfect for low-cost training, small-game hunting, or just ringing steel without breaking the bank on centerfire ammo. Built to fit Glock Gen 4 models 19 and 23, this conversion kit swaps onto your existing frame in about 30 seconds, no gunsmith required. Once you're done shooting .22, pull it off and your Glock is back to its original caliber. It's one of the smartest ways to maximize trigger time and keep your skills sharp between range sessions.

The kit comes with adjustable sights so you can dial in your shots at different distances, and the last-round lock-open feature gives you that satisfying visual and tactile feedback when the magazine runs dry—just like shooting your center-fire gun. That's a nice touch for practice that translates directly to your primary carry or duty routine. Whether you're a competition shooter looking for affordable practice ammo or a hunter who wants a .22 pistol without buying a whole new gun, this conversion kit delivers genuine utility.

Advantage Arms backs the kit with a 1-year factory-direct warranty, so you've got peace of mind on your investment. The 4.02-inch barrel keeps the overall profile compact and handy, making it a natural fit for shooters who already trust their Gen 4 Glock 19 or 23 for carry or duty work.
