How much would a spot weld on the side of a USGI frame weaken it. There is a 3/8x1.5 in stainless steel ID tag, spotwelded just ahead of the serial # and the slide stop hole. There are about 8 very small pinpoint welds that were just enough to hold the tag in place, but it came off quite easily. You can also see correspoonding marks on the opposite side of the frame, small little fisheye's, probably where the other electrode contacted. I just need to know if its ok to shoot. And by the way, I have no clue what the tag was put there for. ??
