USP (German: Universale Selbstladepistole, English: universal self-loading pistol) is a semi-auto pistol developed in Germany by H&K as a replacement for the H&K P7 Series. This new family of pistol was focused on the US Civilian and law enforcement market. In 1991, USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by USSOCOM and result in MK23 Mod 0. Then the USP prototypes were refined in 1992 based on the OHWS trials and finalized the design. USP was formally introduced in 1993 with the USP40 model (chambered the .40 S&W cartridge) and USP9 (chambered the 9x19mm cartridge), and later the USP45 model (chambered the .45 ACP cartridge) in 1995.
