Made in Germany and imported by HKI, this USP Compact carries German proof marks including the DE country code, CIP N nitro proof, and German proofs by the ejection port, plus a "Made in Germany" frame plate. These marks confirm its origin and test standards.
The slide wears HK’s Hostile Environment (HE) nitrocarburized black finish over a robust construction, paired to a fiber-reinforced polymer frame in black. The grip features aggressive texturing for positive purchase in a compact, carry-friendly footprint.
Its 3.8 in cold hammer-forged barrel uses polygonal rifling for durability and a smooth bore surface. The pistol operates on a recoil-operated, modified Browning-type locking system assisted by HK’s recoil-reduction system for controlled cycling.
Controls include a paddle-style magazine release and an S/F control lever. Tru-Dot tritium night sights are installed in a low-profile 3-dot configuration for consistent sighting in varied light. The dust cover integrates the USP proprietary accessory rail.
Chambered in .45 ACP with a 10+1 capacity, this example includes one 10-round and two 8-round magazines. The magazines have witness holes numbered appropriately (10 on the 10-round magazine and 8 on the 8-round magazines), and a mix of extended and flush baseplates is present.
