"The USP is a legend in the line of duty, and the HK USP9 (V7) LEM 9mm Semi-Auto Pistol simplifies operation with the addition of the LEM (Law Enforcement Module) trigger system. The LEM trigger combines all the advantages of a cocked striker-fired trigger (which provides the exact same trigger pull from the first shot to the last) with a double-action hammer system. The LEM trigger is always the same, and it reduces the chance of unintended discharge. The lack of manual safety further simplifies use; the pistol is ready to fire as soon as it's drawn. 4.25"" barrel with polygonal bore profile for enhanced velocity, easier cleaning, and longer barrel life. Specially designed captive recoil spring assembly with absorber bushing helps the USP9 provide softer shooting. One-piece machined slide made from nitro-carburized steel. No-snag bobbed hammer. Corrosion-proof, fiber-reinforced polymer frame. Includes 2 magazines.
