HK's P2000 and incorporate features of the successful HK USP Compact pistol with the latest innovations of HK engineers. A refinement of a design created for several European police agencies, the P2000 is available with a traditional double-action/single-action trigger mode and the LEM/CDA (Law Enforcement Modification, also known as Combat Defense Action) trigger system first introduced in 2001 on the USP Compact "LEM" model. 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 P2000. The enhanced LEM trigger system combines the reliability of a double action revolver trigger with the crisp, precise trigger of a single action pistol.
