Hi all, I was shooting my G37 today. I have installed a minus connector and a Zev light striker spring. I am using a Zev as I tried a Wolff spring and it didn't play well with the trigger safety reset and I have had good luck with Zev in that regard. However,today I had one light primer strike on a Fiocchi 124gr .357 Sig fmj round. Does Fiocchi use "hard" primers? It happened once out of 200 rounds. I haven't had this issue before with Wolff 4lb springs. The primer was marked with a tiny round dimple in the center, not the typical Glock mark. Should I go back to a factory striker spring or will an extended tip striker prevent this? TIA Wanna kill these ads? We can help!
