Description
Rimfire practice is the smartest way to shoot more without draining your wallet, and this Advantage Arms conversion kit lets you do exactly that on the Glock 26 or 27 you already own. It drops right onto your existing Gen 1 through Gen 5 subcompact frame, swapping your 9mm or .40 S&W slide for a purpose-built .22 LR setup. You keep the same grip, the same trigger feel, and the same manual of arms, so range time doubles as real training with a fraction of the ammo cost.
What the Advantage Arms 26/27 Kit Brings to the Range
The slide is CNC-machined aluminum, which keeps it light enough to cycle the low-pressure .22 LR round, and it sits on a 4140 steel barrel for durability. The barrel wears a 1/2×28 thread pattern with a thread protector included, so screwing on a suppressor or muzzle device is a simple job. The slide is recessed for a red dot, giving you a clean home for the optic of your choice when you want to work on target acquisition.
Feeding the Conversion Kit Right
Rimfire is finicky by nature, and the ammo you pick makes or breaks reliability with any conversion. Advantage Arms leans hard toward high-velocity 40-grain round nose loads, with CCI Mini Mags being the crowd favorite for consistency across production runs. Remington Golden Bullets also earn solid marks from longtime owners. Steer clear of hyper-velocity rounds like Stingers and avoid Remington Thunderbolts. Keep the kit properly lubricated per the instructions and it tends to run smooth right out of the gate.
Why Glock Owners Grab This Kit
This conversion pays for itself fast if you shoot with any regularity, since bulk .22 LR costs a small slice of what centerfire runs. It's a great teaching tool for newer folks and younger shooters thanks to the mild recoil, and it lets you rack up reps on a frame you've already dialed in to your liking. The package rounds out with two 15-round magazines and a soft range bag to haul it all.

Frequently Asked Questions
Will this Advantage Arms kit fit any Glock 26 or 27?
It's built for the Glock 26 and Glock 27 across Gen 1 through Gen 5 frames. The slide drops on just like your factory slide and keeps all your normal Glock controls, including slide lock on the last round. Do note that heavily modified triggers, especially aftermarket connectors like the Ghost Connector, can affect how reliably the conversion cycles.
What .22 LR ammo works best in this conversion kit?
High-velocity 40-grain round nose loads are the sweet spot, and CCI Mini Mags have the strongest reputation for run-to-run consistency in these kits. Remington Golden Bullets are another dependable pick. Skip hyper-velocity ammo like Stingers and steer clear of Remington Thunderbolts, since rimfire reliability leans heavily on picking the right ammo and keeping the kit lubed.
Can I run a suppressor on the threaded barrel?
Yes, the 4in barrel comes threaded in 1/2×28 with a thread protector, so it's ready for a rimfire suppressor or muzzle device. Keep in mind that with subsonic ammo and heavier cans, cycling can get pickier as the kit gets dirty, so regular cleaning helps keep things running when suppressed.
Is the slide set up for a red dot?
It is. The slide has a recessed cut designed to accept a variety of red dot options, though the optic itself isn't included. That makes it an easy platform for working on sight picture and target acquisition without buying a whole new pistol.
