The Ruger SR1911 Competition 10-round 9mm magazine is a factory original component built to the same standards as your SR1911 pistol. If you're running this 1911 platform for competition, training, or duty use, having a reliable spare magazine—or a full rotation—keeps you shooting without interruption. This stainless steel magazine feeds the 9mm Luger round cleanly and locks into your SR1911 frame with the precision fit Ruger engineered into the design.
Ruger factory magazines are manufactured to tight tolerances and built to last through thousands of rounds. The durable construction handles regular loading, unloading, and the wear of competition or range use without losing reliability. Whether you're running multiple stages at a match or stocking spares for duty carry, knowing your magazine will perform when you need it matters.
The 10-round capacity keeps you compliant in restricted states while delivering the round count needed for most shooting disciplines. Stainless construction resists corrosion if exposed to the elements during training or field use, and the robust design tolerates the abuse that comes with serious shooting.
