    Default TGS LEM trigger

    Apologize if this has been covered fully in the past, but my HK immersion is more like the dip of a toe.. In reviewing the posts about the TGS LEM modification, I'm trying to understand what the change from a v1 trigger would be. Does it simply produce a slightly heavier trigger pull and a more "forceful" reset? It does nothing to change length of the trigger pull or reset, correct?

    A LEM conversion will provide a consistent pull from the first shot to the last. Trigger slack take up is increased 2-3X over your current V1 SA mode, good for CCW, has some draw backs for some for target shooting. It can be set up as LEM light, medium or heavy pull weights with different springs, so can the V1. Everything consistent the pull and reset is about he same between V1 and the LEM, any mods like trigger work, short reset mods works the same for both versions. Make sure you have a good understanding of the LEM, many like it, some don't.

    You are on the right track but v1 means different triggers on different guns. If you are referring to LEM I think that is the consensus.

    Compared to the V1 "light" lem yes...

    Depending on the gun, you use the heavier trigger return spring (which oddly seems to be more prone to breakage than the smaller diameter roundstock light TRS spring). The increase in trigger pull (mostly on the take-up) is slight but the higher poundage spring in the trigger for return obviously is notable as well. I feel that the benefit to trigger return is worth the penalty.

    Todd was obviously no stranger to shooting a pistol well and knew what he was was trying to achieve.

    I run the TGS LEM in my 9mm P30SK, USP full-size , and USP compact and am working to convert my USP 45 to TGS LEM as well. I happen to think it is the perfect trigger setup for AIWB carry (or really any other carry position for that matter).

    Yes, I should have specified moving from v1 LEM to a v4 TGS on a P30.

    V4 and V-TGS are different so it is not correct to refer to V-TGS as V4.
    V4.1 consists of 3 new parts (4, actually, for your P30)

    What are the differences between stock V4 and Todd's modifications, if you don't mind to elaborate?

    Perhaps this Springs Reference Chart will address your question.
