Sharkbite is right. The trigger is being reset by the striker. Glock require some trigger over travel, or the crucifix won't go high enough to catch the striker after the shot. One of the ghost kits allows the user to take out the over travel, but it require fitting. I would suggest put a bit more over travel back in.
All these "fine tuning" mostly work at the expense of reliability. It is OK if the pistol is solely for sports purposes, not for defense or duty.
