Hi all. Anyone have a hammer for this gun? Maybe I shouldn't screw around with it anymore and leave it alone. It works fine in DA but the gun was failing to stay at full cock. I tried filing the full cock notch slightly and it will stay cocked now, but when you go to pull the trigger it want to decock rather than fire. I think that its only going to get worse since the case hardening is probably all gone from the full cock notch. Any suggestions? Thanks.
