I've stripped my USPc twice, though not completely (didn't remove trigger or mag catch). Once to convert to LEM, and once to convert back to V1. Was easier to go to LEM (since I had the directions that came with the LEM pack). Going back, I had to read the directions in reverse.
For those that have done it, is the P2000 easier / harder / about the same in difficulty detail stripping, in comparison to the USP??
