The Rock Island 54180 is a factory-spec 17-round magazine built for Rock Island Armory A-series 1911 pistols chambered in 9mm Luger and .22 TCM. If you run a full-size or mid-size A-2 model in either caliber, this blued steel magazine gives you reliable capacity and the same fit and function as the original equipment. Steel construction with a polymer base plate means it's tough enough for duty use and range sessions alike, and it's manufactured to Armscor's tolerances so feeding is consistent and trouble-free.
Whether you're stocking spares for competition, training, or defensive carry, having extra magazines on hand is non-negotiable—and having them built to OEM spec keeps your gun running the way it should. This is the magazine Rock Island Armory designed for their own pistols, so there's no guesswork about compatibility or performance.
A solid, no-nonsense choice for any serious 1911 shooter who trusts their Rock Island platform and wants magazines that live up to the same standard.
