I recently picked up my Star 380 ss and put 100 rounds of FMJ through it with no problems. The problen came when I got it home and took it down for cleaning. I ralized that one of the grip pannel screws is shorter than the other three. It is literally shorter, I compared them to make sure. All of the holes in the pannels aprear to be tapped to the same depth. This made putting the pannel back on difficult but I got it to work. Is this normal on this gun or can I get a new set of screws from somewhere that are sure to be the right ones?
