Maybe slide velocity is too low. Try 124gr ammo....
From what I've been told by other members it's likely just shooter technique, not the gun. So I guess i'm out of luck and need to just sell it and get a revolver. I've had carpal tunnel issues in the past so it's a reasonable assumption. It sounds like 9 out of 10 that went back to the factory for repairs had no problems. Or something like that.
