The HK USP (Universal Self-loading Pistol) is one of the most extensively tested and proven duty pistols in the world, in continuous production and service since the early 1990s. Available in 9mm, .40 S&W, and .45 ACP with a polymer frame, it offers multiple trigger variants to satisfy the full spectrum of agency requirements. The USP was designed from the ground up for a long service life, with a recoil reduction system that dramatically extends component life and reduces felt recoil. Its adoption by major U.S. law enforcement agencies and military units — including the Navy SEALs with the Mk23 variant — is a testament to its reliability.
