An improvement to the highly regarded USP45 released in 1995, the HK45 is packed full of user-inspired enhancements. The HK45 pistol features changeable grip panels, a picatinny mil-std-1913 rail, proprietary o-ring barrel, 30% reduced recoil, and USP-style control lever. Ideal for personal defense, the HK45 can also be converted into DA/SA or DAO.
