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 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.

Developed especially for a U.S. 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.

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. 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. Trigger pull on conventional double action pistols is 12 – 15 pounds (53.4 – 66.7N).

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. Optional adjustment (by 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 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.

A set of simple-to-install modular grip panels allow the P2000 to be custom-fitted to any shooter’s hand. An ambidextrous magazine release and dual slide release levers make handling the P2000 natural and easy for right and left-handed shooters alike.

Industry standard mounting rails allow the widest variety of lights, laser aimers, and accessories to be added to the P2000 by sliding them onto the open rail system. The HK P2000 includes the same recurved, hook trigger guard found on the USP Compact and uses reliable and widely available USP Compact magazines.

A limited edition P2000 German Police Model features a “closed” accessory mounting rail system and a tapered trigger guard.
