I do make it a point to routinely fill the mag and cycle while shooting, which oddly seems a rarity at the range these days. I've had and witnessed so many feeding issues surface when recoil is added that I wouldn't take a rig afield without confirming functionality first.
Yep, you don’t see many guys worried about this kind of thing outside of the military and police communities, and an extremely small percentage of preparedness minded civilians. And even amongst those groups, it’s only a few that truly test their equipment and themselves under any real stress.
Fortunately, most of us will only ever hunt non-dangerous game.
