The HK USP (Universal Self-loading Pistol) is the first service pistol based on a modular concept. During development of the USP, the requirements of the Military and Security forces have consistently been taken into consideration. It is the first HK pistol designed especially for American shooters. The modular design of the USP enables an individual adaptation of safety and trigger mechanisms to any requirement.

Features favored by U.S. law enforcement and military users provided the design criteria for the USP. The controls are uniquely American, influenced by such famous designs as the Government Model 1911 pistol.

Thanks to the use of an improved Browning locking system with a patented buffer system, the USP recoil behaviour is unobtrusive even during the use of the highest powered ammunition. The buffer system reduces recoil forces and increases both service life of the pistol as well as improves recoil behaviour.

All USPs use a fiber-reinforced polymer frame stiffened by stainless steel inserts at areas subject to stress and friction. HK pioneered this use of polymer materials in the production of handguns more than 30 years ago with the development of the VP70Z and P9S pistols.

The 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.This same recoil reduction system has been tested and proven in the HK Mark 23 pistol developed for the U.S. Special Operations Command. the USP recoil reduction system is insensitive to ammunition types and requires no special adjustment or maintenance. It functions effectively in all USP models.

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 can also be converted from one type of trigger firing mode to another. This includes combination double-action and single-action (DA/SA) modes and double action only (DAO) modes.

The USP is available in nine trigger/firing mode configurations and three calibers. 9mm, .40 S&W and .45 ACP.
