I carry a P30 LEM, I think going on ~3yrs now. I sometimes carry a P2000, but I find I keep coming back to the P30 for several reasons. Mine currently has the 4.1ch kit (part numbers in the
LEM reference), medium weight trigger return spring (#234773),
GGI flat trigger, and a
GGI SRS. It's my favorite combo so far. IIRC, mine measured at a 5.0# pull. Standard V1 light LEM is more like a 4.5# pull. Not excessively light, which I like to see for a carry gun. In particular, I find the medium weight TRS to be a fantastic balance for the P30. For my preferences, I don't like the standard V1 light configuration as much due to the lighter return spring, as it also results in a lazy reset.
The nice thing about LEM is the length of pull for the first shot. It gives you time for more feedback during the trigger pull, and potentially a bit more margin for error to determine whether you should really be taking that shot or not. The length of pull is not a significant detriment to shooting fast, especially given some of the lighter LEM configurations.
For carry, I use a
JMCK AIWB 2.5. Since the P30 is just a bit larger than say a P2000, having a holster that rotates the grip inward (in this case because of the wing claw) helps immensely with concealment.
