I'm assuming hollow points, just wondering what has been trouble free in the GC3? I have had not the best results with ZSR ammo (misfires, center dented but no bang). Only shot FMJ, but other than the ZSR, have had no trouble at all with other brands. I'm working on my sandbag range and hope to be shooting hollow point in the next week. What defense ammo have you found to be reliable with this gun?
