Description
Running centerfire through your carry gun every range trip adds up fast. The Advantage Arms AAC19-23G5MOD conversion kit lets you drop a .22 LR slide onto your existing Gen5 Glock 19 or 23 frame, so you get cheap trigger time without buying a whole second pistol. You keep the exact grip angle, trigger, and controls you carry every day, which is the whole point when you are building muscle memory.
What the AAC19-23G5MOD Conversion Kit Brings to the Bench
The kit is built around a CNC-machined, optics-ready aluminum slide with a recessed cut that accepts a variety of red dot footprints, so you can mirror the setup on your duty or carry gun. Under that sits a 4.02 inch steel barrel and a steel recoil system, plus fixed Glock-style sights and a clean black finish. It ships with two 10-round magazines and a range bag to haul it all. There is no red dot included, so plan on bringing your own optic.
Getting the Kit Onto Your Glock
Installation is genuinely a 30 second job. You pull your factory slide the same way you would to clean the gun, slide the Advantage Arms unit onto the frame until it locks up, drop in a conversion mag, and you are ready to shoot. No tools, no gunsmithing. The kit is designed to run on factory stock Glock frames, and aftermarket trigger parts or connectors can throw off reliability, so the cleanest results come from a stock trigger group.
Feeding the AAC19-23G5MOD Right
Like any .22 semi-auto, this one has opinions about ammo. Advantage Arms leans hard toward high velocity 40-grain loads, and real-world use backs that up: CCI Mini-Mags and Remington Golden Bullets are longtime favorites that tend to run clean and consistent. Keep the slide well lubricated, wipe it down every few hundred rounds since rimfire runs dirty, and skip hyper-velocity stuff like Stingers. Feed it what it likes and it will happily eat brick after brick of cheap .22 while you sharpen up.

Frequently Asked Questions
What Glock models does the AAC19-23G5MOD conversion kit fit?
This kit is built specifically for the Gen5 Glock 19 and Glock 23 frame. It drops right onto a factory stock frame using the same steps you use to swap your slide for cleaning. For the best reliability, run it on a stock trigger group, since aftermarket connectors and trigger bars can affect how the kit cycles.
What .22 LR ammo works best in this Advantage Arms kit?
Advantage Arms recommends high velocity 40-grain loads, and shooters consistently report the best results with CCI Mini-Mags and Remington Golden Bullets. Avoid hyper-velocity rounds like CCI Stingers and stay away from standard velocity target ammo. Keep the slide well lubricated and the kit will run reliably through bulk practice sessions.
Does the conversion kit come with a red dot sight?
No, the optic is not included. The slide is machined with a recessed cut that accepts a variety of red dot footprints, so you can mount your own to match the setup on your carry or duty gun. It also ships with fixed Glock-style iron sights if you want to run it as-is.
How long does it take to install the AAC19-23G5MOD kit?
Installation takes about 30 seconds and needs no tools. You remove your factory slide, slide the Advantage Arms unit on until it locks up on the frame, and insert one of the included conversion magazines. Swapping back to your original 9mm or .40 slide is just as quick when you are done.
