The Advantage Arms Conversion Kit for Glock 17/22 Gen 3 transforms your duty or carry gun into a dedicated .22 LR trainer—keeping range sessions affordable while building consistency without the recoil and noise of centerfire rounds. Whether you're running a high-round-count practice day, introducing a new shooter to fundamentals, or just plinking on a budget, this conversion kit lets you use your familiar Glock ergonomics and controls in a much gentler package. It's a smart way to log dry-fire trigger time and live practice on the cheap without needing a completely separate firearm.

The AAC17-22G3MOD is engineered to fit Glock 17 and Glock 22 frames in Gen 1, Gen 2, and Gen 3 specifications. You get a complete drop-in solution: a 5-inch threaded barrel, two 15-round magazines, and a range bag to haul it all. The kit includes a recessed cut machined into the slide to accept a variety of common red dot sights, so you can mount your optic without modification or gunsmithing. That threaded barrel also opens the door to suppressed .22 shooting if you have the tax stamp and a suitable can—a quiet, economical way to extend your training without disturbing the whole range.

At 6.5 ounces, the conversion kit is light enough that your gun's handling and balance will still feel familiar once you're back on your duty round. The .22 LR round is inherently softer to shoot and easier to control, making it ideal for shooters of all experience levels who want to refine their sight picture, trigger press, and fundamentals without flinching or fighting recoil. Note that the optic and host handgun are not included—you'll need to supply those separately.
