Hi all, I just assembled my first glock frame, this is the third frame that I have printed. Prints came out solid with Polymaker PLA Pro. Assembled with OEM lower parts kit and aves rails. PSA Dagger slide. Chairmanwon G19 files. Passes all function tests, but every time I have attempted live fire, I am getting light primer strikes. Slide works flawlessly on other non-3d printed frames. Multiple types of ammo have also been tried. I also switched the striker spring to an OEM g19 spring that has more force than the PSA spring. Still getting light primer strikes.

I noticed that the trigger mechanism has a little play forward and backwards and was thinking it could be causing the light primer strikes. Does anyone have a good solution to secure the trigger mechanism? I was thinking of adding some epoxy in the gap, but don’t want to have the trigger mechanism housing stuck in the frame.
