Anyone try em in a SA champ.? I ordered 2 , they work flawlessly with FMJ, but not with HP's. I looked em over and they seem to have a larger mouth/feed area on the front. So I tried swapping the springs and follower into a colt mag I have. Trying to get 8 rnd reliable mags. As I do not have my SA right now, will have to wait and see if they work.
