Like the slightly larger P2000 model, the P2000 SK (subcompact) combines elements of the successful HK USP Compact pistol with recent technological innovations from HK engineers only in a smaller, more concealable design. The P2000 SK is available with Law Enforcement Modification (also known as Combat Defense Action) trigger system introduced in 2001 on the USP Compact "LEM" (Law Enforcement Modification) model. This unique pre-cocked hammer system combines the advantages of a cocked striker component (constant level of trigger pull and short trigger travel from first to last round fired) with a double action hammer system. The LEM/CDA trigger pull has been reduced to 7.3 - 8.5 pounds of pressure (32.5 - 37.8 Newtons), compared to 12 - 15 pounds (53.4 - 66.7 N) found on many conventional double action pistols. Optional adjustment by an HK certified armorer can bring the trigger pull into the 5.5 pound (24.5 N) range. Using such an enhanced trigger system consolidates ease of use and safety into a convenient, innovative trigger operation one that prevents unintended firing. And in case of an ammunition-related failure to fire, all that is needed is an additional second or third pull of the trigger without the need of first pulling the slide back to re-cock the Subcompact. The enhanced LEM/CDA trigger system combines the reliability of a double-action revolver trigger with the crisp, precise trigger of a single-action pistol. For shooters that prefer a conventional double-action/single-action pistol, a double-action/single-action variant is also available with a decock button mounted on the rear of the frame. A choice of two simple-to-install grip panels make it easy to custom-fit the P2000 Subcompact to any shooter's hand. And the same ambidextrous magazine release and dual slide release levers found on the P2000 make handling the Subcompact easy for both right- and left-handed shooters. A set of abbreviated "industry standard" mounting rails on the P2000 SK enable lights, laser aimers, and other accessories to be added by sliding them onto the open rail system. The HK P2000 SK also can use widely available, reliable USP Compact magazines.
The HK USP Compact is a small frame pistol capable of firing the most powerful cartridges in 9 mm, .40 S&W, .45 ACP, and .357 SIG (by special order). 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. 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 by a polymer absorber bushing. Service life is still engineered to exceed 20,000 rounds. Easy to shoot, simple to maintain; the USP Compact is a reliable, safe, accurate, and highly concealable pistol.
