I have two Glocks, a 19 and a 20. The 19 is great. The 20 has been giving me trouble, and I can't seem to figure it out. It is absolutely reliable with factory ammo. I get a fair amount of light hits, almost 10%, with even very good quallity reloads. (My own). I get a centered light hit. A second strike fires the round. There is a brand new factory firing pin and a brand new factory firing pin spring. The channel isn't gunky, and I cleaned it out anyway. The firing pin safety seems to be working normally and the trigger bar is not deformed. Extractor tension seems normal. Any suggestions will be greatly appreciated. Wanna kill these ads? We can help!
