The HK USP (Universal Self-loading Pistol) is an accurate and ultra-reliable handgun. It utilizes a fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction. The control lever, a combination safety and decocking lever, is frame mounted and quickly accessible, unlike the slide-mounted safeties. The modular design of the USP's internal components allows the control lever function to be switched from the left to the right side of the pistol for left-handed shooters. The USP features a polygonal bore barrle, one-piece steel slide extended release, universal mounting grooves, and ambidextrous magazine release lever. This V1 model has a black frame with blued slide, night sights, and comes with three 10-round magazines.
