As I mentioned I have never had a failure to fire with this gun. Thus was my first box of Hornady CD 9mm and had this. Leads me to believe it's the ammo not the gun. All the ones that fired have the indent in the same place

I keep a log book on every new gun I buy for SD and record all ammo, number of rounds and any failures. I usually am looking for gun failures such as fail to feed, fail to eject and other jamming. I just pulled out my records. Without listing every date (start 9/2007), I have around 600-700 rds through this gun with PMC, WWB, Fiochi, Magtec, Corbon,Blazer Brass, Rem, Speer Win Ranger, Fed Hydo, Fed HSt and handloads. NEVER a failed primer.
