I have both. I initially thought I would trade off the P30 for a VP9, but I like the LEM trigger better than the VP9. I run the P30 better also. This isn’t me saying the VP9 is an inferior gun though!
I treat the light LEM trigger like a revolver. Just a smooth, consistent pull and the shots go where they belong. Don’t try and stage the trigger like some revolver shooters do though. The LEM doesn’t work that way.
