Advanced Arms Conversion Kit for Glock 19/23 Gen 5 - California Compliant

The Advanced Arms Conversion Kit for Glock 19/23 Gen 5 transforms your full-power duty gun into a dedicated .22 LR trainer, letting you build fundamentals and muscle memory without the recoil, noise, or ammunition cost of centerfire shooting. Whether you're breaking in a new shooter, running drills on a budget, or just want a softer platform for high-volume range sessions, this California-compliant kit gives you a practical second life for your Gen 5 Glock 19 or 23.

The MOD-CA conversion slides onto your existing Glock frame, converting caliber and handling in one swap. You get two 10-round magazines to keep rounds downrange, and the kit features a recessed mounting surface that accepts a variety of red dot optics—letting you practice with the sighting system you'll actually run on duty or in competition. A padded range bag keeps everything organized and protected between sessions.

This is legitimate training gear, not a gimmick: .22 LR conversion kits have long been the go-to for shooters who need high-round-count practice without fatigue or wallet damage. For instructors, parents introducing kids to shooting, or any serious shooter who logs serious miles downrange, the cost-per-round math alone justifies the kit. And because it's engineered specifically for California compliance, you don't have to second-guess the legality.
