The standard trigger pull for the LEM is the V2 which is approx 8-8.5lbs. You can also go with the V1 LEM which is the lightest pull at approx 4.5-5lbs. The V1 and V2 are the most popular. The LEM conversion costs about $125 which includes return shipping. I had my USP switched to the V1 light LEM and was very happy with the conversion. Turn around time was just about two weeks.I recently purchased a uspc in 357 sig. I'm thinking about sending it back to h&k to have the lem conversion done. Does anyone know what the trigger pull will be with this conversion to lem?
