It was an off centered hole and the edges of the triggerguard toward the muzzle were sticking out to one side of the frame and inset on the other. I disassembled it and put in some screws from some others I have, just to make sure it wasn't a bent screw, but it was still the same. I have no idea how it got built that way.
The replaced it without question though. I only had it one day. I played with it a few hours, trying different screws and tightening sequences, trying to mate it up squarely and then called them that night and they gave me the okay to use the return slip and UPS showed back up to claim it the next morning.
That 'puter crashed last Spring and I don't have the pics anymore.
But it was only one bad one and it was righted quickly.
