mostly, guys don't bother to practice such things because they take too long, when it's for real. Ask Geo Z how much time he had. :-) I wouldn't own a gun that malfunctioned once in 100 shots, much less carry it. Why would anyone do that? Sure, in a melee, things can get into the path of a slide. If that worries you, then use a revolver. Simple enough, right?
