There was also a good video I had seen a while back about whether it was practical during a close combat encounter to hold tightly on the slide of a pistol to prevent it from cycling on to the second round after the first round fired. As long as you have a strong grip on the slide, after the first shot they'd have to manually charge it to get it back into battery again.
It's one of the reasons if you ever need to hold someone at gunpoint, you never push the barrel into them.Strong grip? No you can do that with a weak ass grip, hell you can do it with your thumb on the rear of the slide, that's actually a technique for close retention shooting if you have to get the front of the gun up close and on the target, you but your thumb on the rear of the slide to keep it in battery bang off a round hope you can creat space, tap rack bang on.
In other ways if you can push on the slide/barrel of most semi auto handguns it will kick it out of battery and the first round won't even go off
