I got his stock trigger shoe and for me, it was just as bad as the stock trigger.There are a few good videos on YouTube about filing them. I took the trigger shoe off of a Johnny Glock Evolution Competition trigger assy I had in my G34 and put it into a G42. No more trigger bite and the trigger works flawlessly. It still has about a six pound pull.
Johnny Glock does have some good, instructive videos on Glocks and I have learned a lot. He also sells a stock Glock shoe that is modified for about $25 that would get rid of the bite as well as smoother performance
A couple forums I cruised through while searching for a solution had folks talking up his combat trigger and Evo(?) Trigger shoe. I wasn't looking to spend that kinda money on this and really just wanted to find a new shoe that didn't suck.
I've got a few more mags downrange with the Apex and I'm slowly changing my opinion on it. At first I wasn't happy with it but I may not have given it a fair evaluation cause I was just generally pissed at everything that day.
