The USP9 feature a fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction. The USP control lever, a combination safety and decocking lever, is frame mounted and quickly accessible, unlike the slide-mounted safeties common on many semi-automatic pistols. Variant 7 is a double action without control lever (no manual safety/decocking lever).
