USP Compacts are smaller and lighter than large-frame USPs. The reduction in trigger reach and grip circumference increases concealability and enhances shooting ergonomics. The USP Compact uses a narrow, full-hand grip frame with a choice of interchangeable extended or flush-fitting magazine floorplates. Like their large frame predecessors, USP Compacts are designed with the demanding needs of the law enforcement and military shooters in mind. Using a modified linkless Browning-type action, the USP Compact is built to take the punishment of high-energy +P loads. To reduce the length of the slide and barrel on the USP Compact, the mechanical recoil reduction system found on large frame USPs has been replaced by a specially designed flat compression spring contained in the captive recoil spring assembly. Service life is still engineered to exceed 20,000 rounds. This pistol is a Variant 1 double action/single action with "SAFE" position. The control lever (manual safety/decocking lever) is on the left side of frame. Models come with 3 magazines and night sights.
