The Rock Island 54172 is a factory-spec 7-round detachable magazine built for full-size 1911 pistols chambered in .45 ACP—specifically designed to work with Rock Island 1911 CS models. If you run a Rock Island 1911, this is the magazine you need: it's manufactured to the same tolerances and specifications as the original equipment, so you get the reliable fit and flawless feeding you expect from a quality defensive or target 1911 without any guesswork or tuning.
Built with a steel magazine body and polymer base plate, this magazine combines proven durability with smooth operation. Whether you're training at the range, carrying for personal protection, or building a spare magazine setup for your 1911, you want magazines you can absolutely depend on. Rock Island factory magazines are engineered to feed and function reliably cycle after cycle, so you can focus on your shooting instead of worrying about equipment.
At 7 rounds, this magazine holds a standard full-size 1911 load and seats cleanly in the magazine well. The durable construction means it will handle regular use, reloading, and storage without degradation—essential for any .45 ACP 1911 owner who treats their gear seriously.
