The Advantage Arms Mag Adv Conv Kit 1911 22LR magazine is a dedicated .22 Long Rifle magazine built specifically for 1911 pistols equipped with an Advantage Arms rimfire conversion kit. Its slim polymer body mirrors the feel of a standard 1911 magazine while providing reliable feeding and a smooth loading experience for economical rimfire practice.

This 10-round magazine is ideal for extended range sessions and skills training where you want to maintain your 1911’s familiar ergonomics without the cost and recoil of centerfire ammunition. The last-round hold-open feature keeps the slide locked back after the final shot, reinforcing proper reload habits and making it easier to confirm an empty pistol. Advantage Arms is known for well-engineered conversion systems that let shooters train more often while preserving the handling characteristics of their primary sidearm.
