Just recently picked up a P30 V2 and wanted to convert to light LEM. I know v1 is what is considered light lem but a friend of mine today mentioned that there is a v4.1? I have done the spring swap (fpb and trs) on an hk45 and p2000sk before to make them light lem before. What would be different about going the 4.1 route? would that also make is as light as the V1 for the p30? from what I understand the main point of it is to lessen travel. Please correct me if I am wrong.
