I recently started shooting a Glock 20 and have fired nothing but my loads out of it. When it was box stock it ran fine but since i put a spring kit in the slide and a new connector I had 4 failures to fire and the trigger failed to reset once.. I am using WLP primers and wondering if there is a different primer I could use that would work with the reduced power firing pin spring? I really like the trigger pull now and would hate to go back to the factory 5.5# springs. This will not be a carry gun,mainly range and maybe hunting. It's my first Glock and so far I'm impressed with the accuracy and how it handles the 10mm round. Any suggestions?
