The HK45 was developed as a product improvement of the highly regarded USP45, first released in the 1995. The Caliber .45 ACP HK45 includes several user-inspired enhancements including changeable grip panels (backstraps), a Picatinny MIL-STD-1913 accessory rail, better ergonomics, and more ambidextrous controls.
The HK45 Tactical features a threaded barrel for suppressed use and high profile sights. The barrel uses an O-Ring for improved slide to barrel lockup and enhanced accuracy. The HK45 Tactical utilizes a proprietary internal mechanical recoil reduction system that uses a flat recoil spring in conjunction with a polymer bushing to reduce recoil forces and prolonging component service life.
The V1 features a Single-Action/Double-Action mechanism with a safety/decocker lever.
