Easy to shoot and simple to maintain, the USP Compact is a reliable, safe, accurate, and highly concealable pistol. Unlike sub-compact semi-automatic 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. With the same modified linkless Browning-type action found in the full-sized USPs, the Compact is built to take the punishment of high-energy +P loads. To reduce the length of the slide and barrel, the mechanical recoil reduction system found on large frame USPs has been replaced by a specially designed flat compression spring contained in the captive recoil spring assembly by a polymer absorber bushing. Additional features include: a flared, recurved trigger guard and a universal mounting grooves for installing accessories. The USP Compact Variant 1 has a manual thumb safety and is capable of firing in both single and double-action.
