Using the common lineage of the USP and developed in conjunction with internationally renowned target shooters, the USP Expert achieves the highest levels of accuracy by combining features of the HK Tactical and Mark 23 pistols with a long slide design. The result is a USP ideally suited to IPSC and other practical target shooting applications. Like all USPs, the Expert has an O-ring barrel with a polygonal bore profile. The elongated, milled target slide is made from nitro-carburized steel and given a corrosion-resistant "Hostile Environment" blued finish. The fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction. Ambidextrous control levers on both sides of the frame, an ambidextrous magazine release lever, and an extractor doubles as a loaded chamber indicator makes the Expert user-friendly and adaptable. The target sights are micrometer adjustable for windage and elevation. Match grade trigger. Front mounting rail. Oversized trigger guard. Jet funnel magazine well attachment included.
