I went and shot about 6 rounds by myself today. When I was donea dn started to clean my gun I noticed alittle line and a very very small hole on the face of the frame. It was there before just wandering if this is gauling? I thought that I had put enough grease on there. I know the picture isn't that great but maybe you can tell. Its in the bottom left hand side of the picture. If this is gauling, what can I do about it?
