i find it hard to believe that CS isn't helping out.
As hard as it is to believe
....I contacted cva customer service the first time it happend, I was told it was a cleaning issue, that oil and debris were getting into the trigger mech area and not letting the barrel lock thus not letting the hammer lock back. I know 2 of them are using winchester primers. I know all 3 of the guns were bought 3 years ago
