Something unusual happened to my GP 100 at the range yesterday. I put about 20 .357 through my revolver when the trigger suddenly disengaged. It was swinging as if it were free. I engaged the hammer and everything when back into place. I finished my time at the range without incident. Since this is my preferred carry I practice regularly and clean it after each practice. This has never happened before. I fully disassembled and polished and oiled. It didn't seem especially grimmy, but I would hate for this to happen when I need it to perform. I would appreciate any thoughts or advice on this.
