This compact .40 S&W features the factory Stainless slide variant with a matte stainless finish over a black polymer frame, giving it the distinctive two-tone USP Compact look. It is German-made and marked with the Ulm antler proof, DE marking, AK date code, and HKI Columbus GA import mark.
The operating system is double-action/single-action with a short-recoil tilting barrel and an external hammer. It uses HK's modular USP control-lever system (convertible by an armorer) and includes a manual safety. The paddle-style ambidextrous magazine release supports quick, positive magazine changes.
The 3.5 in barrel uses polygonal rifling, and the captive recoil assembly incorporates a polymer buffer. Sights are fixed 3-dot with dovetailed front and rear units for durable alignment.
Capacity is 10+1. The frame integrates HK's proprietary USP accessory rail. Grip surfaces include pebble-texture panels with checkered frontstrap and backstrap, along with the molded USP logo for a secure, consistent hold.
