I am VERY familiar with high stress combat shooting, and I have been involved in situations throughout my career that have proven both your point AND mine. You are correct that a single center mass shot is not likely to stop someone immediately, although it has on occasion. Alternatively, a shot to the eye/brain is very effective in stopping an assailant. The question comes down to training and experience while shooting with induced stress. Joe average shooter is not likely to have enough of either, but a competent marksman with a cool head in a stress environment can prevail with almost any caliber weapon.
The only reason I mentioned your post is that on the surface the comment you made was fallacious in the limited context in which you mad it. I am not trying to argue either, only clarify that a single, well placed shot can stop an attacker. And that the larger the caliber, the more effective that single shot will be.
Also, what was your stress course? I'm curious to know how much your shooting skills deteriorated during the course and what you learned form the training.
