Mag Rock Island 22tcm/9mm 10rd

The Armscor Rock Island 22TCM/9mm 10-round magazine is a factory-original single-stack 1911 magazine purpose-built for full-size Rock Island Armory 1911 models chambered in .22 TCM. This stainless steel magazine combines OEM manufacturing standards with proven reliability, offering operators and enthusiasts a direct replacement that meets the exacting tolerances Armscor applies to all original equipment magazines.

Constructed from stainless steel with a polymer base plate, the magazine delivers corrosion resistance and dependable feed reliability across extended use. The 10-round capacity is optimized for the .22 TCM cartridge, which delivers centerfire performance in a compact platform. Stainless steel construction resists oxidation in varied environments—a critical consideration for duty-carry weapons and storage in coastal or humid conditions. The polymer base plate provides impact absorption during tactical reloads and field use without compromising retention or durability.

This magazine is designed for users who operate full-size 1911-pattern pistols in .22 TCM and require OEM-spec replacement magazines for duty carry, training rotations, or backup magazine stockpiles. The .22 TCM round occupies a distinct niche—offering higher velocity than 9mm in a single-stack platform—making magazine compatibility non-negotiable. Serious shooters know that factory magazines manufactured to the same specifications as original equipment ensure zero compatibility surprises during critical moments.

Rock Island Armory magazines are recognized in the market for consistent fitment and function across their 1911 lineup. This 10-round variant for .22 TCM ammunition gives operators a reliable spare or rotation magazine without the need to search aftermarket sources or compromise on specifications.
