USP
HECKLER & KOCH USP PISTOLS
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.
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.
The modular design of the USP enables an individual adaptation of safety and trigger mechanisms to any requirement.
