Curious if anyone else has experienced this. I have an M&P 9mm, and sometimes when the pistol ran dry and the slide is locked back I'd slam home a loaded mag only to have the slide release on its own. I know this is less of a concern than stoppages for instance, but still I want to be in control of chambering process. Also, fyi, I do not use the slide release to chamber a round I do it by pulling the slide back and letting it slam home. So there is no wear-out problem causing this. One thought was that the Win White box ammo I was shooting is fairly under-charged so perhaps it was barely locking the slide back, if that is possible?
