Advantage Arms .22 LR Conversion Magazine for Glock 20/21

Affordable Training for Your Duty Pistol

The Advantage Arms .22 LR conversion magazine is purpose-built for shooters who want to maintain their skills without the cost of full-power ammunition. This polymer magazine holds 10 rounds and pairs with the Advantage Arms conversion slide kit to transform your Glock 20 or 21 into a rimfire trainer.

Key Features

• Capacity: 10 rounds of .22 Long Rifle ammunition
• Material: Durable polymer construction
• Finish: Matte black
• Compatibility: Glock 20 and Glock 21 pistols (requires Advantage Arms conversion slide kit)
• Last-Round Hold-Open: Slide locks back on the final round for easier reloading during practice

Why Choose Rimfire Training?

Training with .22 Long Rifle ammunition costs a fraction of standard duty rounds, allowing you to shoot more and spend less. The reduced recoil and noise make it ideal for extended practice sessions while maintaining the ergonomics and manual of arms of your primary carry or duty weapon.

Important Note

This magazine requires the Advantage Arms Glock 20/21 conversion slide kit (sold separately) to function properly. The conversion kit transforms your pistol's upper assembly to chamber and fire .22 Long Rifle ammunition while maintaining your original frame and controls.
