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.
