I've never had any issues with my 9c and it is my fav firearm. I've had a few FTF on cheap range ammo, blazer brass, range reloads they sell, and one with Remington UMC. They are light strikes - pull the trigger and no bang. happened on my fun and my buddies xdm one range visit. happened twomtimes since.Is this an ammo or firearm issue? It is my EDC and love it, just want to check. Thx!!
