Comes with two hammer springs:
The longer hammer spring is for all USP, USP Compact and full size HK45.
The shorter hammer spring is only for the HK45 Compact.
Use the trigger return spring that is already in your gun for light LEM trigger pull, approximately 4-5 lbs.
Use the trigger return spring in the kit for the heavier LEM trigger pull, approximately 7 lbs.
USP models prior to 2005 will also need 209266 Trigger Rebound Spring.
