I'm looking for comparisons from anyone who has used both of these setups. To be clear:
1) An HK P30 or other recent HK pistol with the LEM trigger system. P30 v2 would be ideal.
2) A gen2-3 Glock with standard trigger bar, a 3.5lb or Glock "-" connector, and the Glock NY1 spring.

I haven't used the LEM but understand the concept. I've used a Glock with the 3.5lb connector and standard spring extensively and like it. Based on pull weights and descriptions, it sounds like the LEM v2 should be similar in weight and feel to a 3.5lb or Glock "-" connector, and the Glock NY1 spring. Anyone?

And for added kicks, if anyone has used one of those and also a Kahr (factory stock), I'd be interested in that comparison too. I have dry fired a Kahr but not live fired one.
