So I was out playing around with my first large batch of reloads today. I came across a failure that I had yet to see, but have read about. When I fired the last round and the slide went back to lock, the mag follower actually slid around the slide stop and jammed the slide about halfway back. I was using Wilson 47T mags when this happened. There were 2 that were giving me problems regularly. When I get home and stripped the pistol I stuck a mag in and found the slide stop to follower engagement to be pretty iffy. All 6 of the followers looked like they were on the verge of slipping around the slide stop. Below is a pic of the engagement between the slide stop and the follower. Is this a problem with my followers or my slide stop?
