Mag Rock Island 1911 22tcm 17rd

The Armscor Mag Rock Island 1911 22TCM 17-Round Magazine is a factory-spec replacement magazine engineered for Rock Island Armory high-capacity 1911 models chambered in .22 TCM. Built to original equipment manufacturing specifications, this magazine delivers the capacity and reliability required for training, sport shooting, and tactical applications where round count matters.

The 17-round capacity makes full use of .22 TCM's ballistic advantages—higher velocity and flatter trajectory than standard .45 ACP from the same 1911 platform—without requiring platform modifications. The steel magazine body with polymer base plate is manufactured to the same tolerances and materials as original Rock Island Armory factory magazines, ensuring consistent feeding, zero compatibility issues, and reliable function across extended shooting sessions. The robust construction resists corrosion and maintains spring tension through thousands of reload cycles.

This magazine is ideal for shooters running modern 1911 variants in .22 TCM who need genuine factory-quality spares. Whether stocking multiple mags for range training, competitive shooting, or duty rotation, the Rock Island Armory magazine delivers proven performance at OEM specifications. The 17-round capacity paired with .22 TCM's ballistics gives operators a high-capacity, flat-shooting alternative to larger-caliber 1911 designs without sacrificing durability or ergonomics.
