I'm having an issue with my apex trigger on my ad40 the gun is brand new anver been shot so I wanted to have the apex kit in it from the get go. I put the spring kit in and every thing worked fin but then came the trigger. I could not for the life of me get my role pin out so I just removed the trigger pin. I got the trigger bar on the trigger and put every thing back together. I racked the slide and the trigger got Hung up on the frame but still went all the way to the frame and there was no firing pin click. I then took the gun back apart and sanded down the trigger like I had seen in another post on here.well this got me a little headway I was able to get the gun to click but only after squeezing the **** out of the trigger and it wasn't consistent. So I sanded down some more now I have a click every 20 pulls of the trigger. I'm not sure if I took of to much material or to little but it seems that the problem is that the trigger bar isn't pushing the striker catch back far enough to release the striker. Does any one know of any thing that will fix this issue.
