Mag Hk Usp-fs 40sw 13rd

The HK USP-FS .40 S&W 13-round magazine is an OEM factory magazine built to Heckler & Koch's exacting specifications and tolerances. Designed for the full-size USP pistol platform, this 13-round capacity magazine delivers reliable ammunition feeding and consistent performance in duty, training, and competition environments where dependability is non-negotiable.

Construction combines a polymer body with a steel spring and polymer base plate, a proven combination that balances weight reduction with structural integrity. The 13-round capacity maximizes on-board ammunition while maintaining reliable feeding characteristics across the full magazine stack. The compact footprint—1.75 × 1.25 × 5 inches—ensures proper seating in USP-FS grip frames without binding or rattle. Field operators and range shooters consistently report trouble-free performance across extended training cycles and duty rotations with these factory-spec magazines.

This magazine serves the needs of law enforcement personnel, security professionals, competitive shooters, and tactical enthusiasts who standardize on the HK USP-FS platform. Operators working with .40 S&W benefit from the round capacity and proven reliability of factory Heckler & Koch magazines, which maintain performance under rigorous conditions where aftermarket alternatives may falter. Whether stocking spares for duty carry or building a magazine rotation for range training, HK factory magazines represent the baseline specification for the USP platform.

Factory HK magazines are the standard against which aftermarket alternatives are measured. The .40 S&W round offers higher velocity and energy than 9mm while maintaining manageable recoil and capacity advantages over larger calibers, making the USP-FS a balanced platform for extended engagement scenarios. Purchasing OEM HK ammunition capacity ensures zero compatibility questions and predictable long-term functionality.
