The HK USP Compact is a small frame pistol capable of firing the most powerful cartridges in 9mm, .40 S&W, .357 SIG, and .45 ACP. Based on the full-size USP models, these handy pistols combine compact size with optimum effective shooting performance.
USP Compacts are smaller and lighter than large frame USPs. The reduction in trigger reach and grip circumference increases concealability and enhances shooting ergonomics. Unlike some subcompact semiautomatic pistols that use a difficult to shoot two-finger grip frame, the USP Compact uses a narrow, full-hand grip frame with a choice of interchangeable extended or flush-fitting magazine floorplates. This makes the pistol easy to shoot without sacrificing concealability.
All variants of the USP Compact have modified contoured slide and frame for effective concealability. Variants 1-7 also have a no snag, bobbed hammer. The extended slide release is contoured to reduce wear and tear on clothing when the pistol is carried concealed.
Using a modified linkless Browning-type action, the USP Compact is built to take the punishment of high energy +P and +P+ loads.
