Optional adjustment (by HK certified armorer) can bring the trigger pull into the 5.5 pound (24.5 N) range. The unique LEM 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. Trigger pull on conventional double action pistols is 12 – 15 pounds (53.4 – 66.7N). The design of the proprietary HK LEM system allows the weight of the DAO trigger pull to be reduced to a smooth and constant 6.18 – 8.5 pounds (27.5 – 37.8 N) because the two-part hammer is pre-cocked every time the slide moves rearward. With this mechanism, HK pistols can be fired like a standard DAO semi-automatic pistol where every round is fired by simply pulling the trigger fully rearward with the hammer starting at the forward rest position.

government agency, the Law Enforcement Modification (or LEM for short), is a unique trigger mechanism created specifically to improve the trigger performance and reduce the weight of the Double-Action Only (DAO) trigger pull on HK pistols. The HK Law Enforcement Modification trigger system combines the advantages of a cocked striker component (constant level of trigger pull from first to last round fired) with a double-action hammer system.ĭeveloped especially for a U.S. 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. The first of the many recent additions to the Heckler & Koch handgun line, the P2000 and incorporate features of the successful HK USP Compact pistol with the latest innovations of HK engineers.
