Yes those are all operator errors but thanks for making a point.The op made allusions to it, not you persé. And, we do agree, although, according to your previous comments, limp wristing the semi-auto doesn’t qualify as a semi-auto failure but operator error, much like not allowing the trigger out far enough on a revolver to reset the trigger in DA mode.
When you limp wrist a auto or accidently hit the mag release you get one shot and then you have to clear the gun malfunction or do a reload or pick up a mag off the ground and hope it hitting the ground didn't dislodge the top round. Either way you are down from a couple of seconds to forever if the mag gets messed up hitting the ground and you don't carry a reload mag.
The revolver you get the same 1 shot and if you short stroke the trigger guess what ....... you pull the trigger again. .02-.05 of a second and you are back in the fight.
