USP LEM & HK45 trigger pull weights quick guide:Use the trigger return spring that may be in any newer production HK pistol or HK part # 209266 (black colored, thinner trigger return spring) for light LEM trigger pull, approximately 4-5 lbs.

Use the square spring shaped trigger return spring in the kit for the heavier LEM trigger pull, approximately 7-8 lbs.

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 in the P2000SK, P2000, USP, USP Compact, HK 45, and HK 45 Compact 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 propriety HK LEM system allows the weight of the DAO trigger pull to be reduced to a smooth and constant 7.5 – 8.5 pounds because the two-part hammer is pre-cocked every time the slide moves rearward. Or a smooth 4.5- 5.5 pounds if the operator opts for the lighter trigger pull configuration.

Please note: The LEM kit will not work in the P2000, P2000SK, P30, P30L, VP9 & Mark 23
