I was running stock polished mil spec trigger with JP reliability spring on a frontier glock lower with cmmg bolt. Had issues with trigger not resetting as well as pins walking out. KNS pins help with the other problem. Took JP springs out and has been flawless since.

That's a nice piece. My pro custom had tomasie slide, KKM bull barrel, gun craft flat trigger, CGW magwell, VZ grips but yours is much nicer. Thanks for posting salamat
