I noticed my trigger pin was walking out the other day. no biggie. I bought a floating trigger pin for it. but for the price of this pistol [$1000]it should have already been there IMO. but I was able to push it in with my thumb. so, question 1 is... do I have to worry about the new one walking out? i also picked up a reduced power trigger spring from CGW. question 2...do i "need" to install this? if so, will it help keep the pin in place better than the stock spring?
