Mag Adv Conv Kit 20-21 22lr

The Advantage Arms Magazine Conversion Kit for Glock 20-21 in .22 Long Rifle is a dedicated 10-round magazine designed specifically for use with Advantage Arms' rimfire conversion systems. This kit allows shooters to train economically with their primary duty or carry pistols by converting them to shoot cost-effective .22 LR ammunition. It is ideal for those looking to maintain their shooting skills without the higher costs associated with 10mm or .45 ACP ammunition.

Constructed from durable polymer, the magazine is engineered for reliability and ease of use. It features last-round hold-open functionality, which locks the bolt to the rear after the final round is fired, providing visual and tactile feedback that the magazine is empty. This design helps preserve muscle memory and training fidelity, mirroring the manual-of-arms on full-power platforms.

This magazine is particularly beneficial for shooters who train with Glock 20 or Glock 21 platforms, allowing for extended practice sessions. Its lightweight design, weighing just 0.25 lbs, and compact dimensions (2 × 1.3 × 8 inches) make it easy to store and transport alongside standard duty magazines. The economical nature of .22 LR ammunition makes high-volume practice sustainable for all types of shooters.
