I have a S9 which I am having problems with. I have only taken it out twice to shoot but the first time I experiances several failures for the trigger to reset per mag. The second time out I had the same problem but now I am geting FTF at least once per mag. On the FTF I am getting light primer strikes at the 12:00 edge of the primer which makes me believe the gun is not fully locked up. There is also dimples in the brass on the head in the 12:00 position extending up to the case rim. Any ideas if this will shoot out or do you think it needs to go back for service?
