Originally developed for the American market, the USP has become internationally known as a reliable and accurate handgun. Meeting the criteria for military and law enforcement alike, the USP uses a fiber-reinforced frame with steel inserts for stiffness and stress reduction. The USP utilizes a recoil system that operates with all ammunition types and requires no special adjustments or maintenance. An easily accessible control lever uses a combination of a safety and decocking lever. Additionally, the control lever can be switched for left or right handed users.
