Heckler & Koch USP 45 ACP 10rd Magazine Black, Extended Floorplate

The Heckler & Koch USP .45 ACP 10-round magazine with extended floorplate is a reliable spare or replacement magazine built to H&K's exacting standards. If you carry or train with a USP in .45 ACP, having backup magazines on the range, in the safe, or on duty is non-negotiable—and this steel detachable magazine delivers the capacity and durability you expect from one of the industry's most trusted sidearm platforms. The extended floorplate adds a small but useful grip advantage when reloading under pressure, giving your pinky finger a place to rest and making magazine changes faster and more natural.

Built from steel and finished in black, this magazine is engineered to feed reliably through thousands of rounds. Whether you're running drills at the range, maintaining a defense-grade battery, or simply stocking spares, a quality OEM or OEM-compatible magazine is worth the investment—cheap magazines are where malfunctions start.

H&K USP magazines are straightforward to load, inspect, and maintain. The extended floorplate design is a small detail that makes a real difference in high-volume shooting sessions or tactical training, and it makes the magazine slightly easier to locate and deploy from a mag pouch.
