Let me try this again and I'll keep Lost Sheeps useful ideas in mind
In this discussion we are not speaking of "gunfights" involving SWAT standoffs or military actions. We're speaking of the little down and dirty ones.
Recall the last time you got into a fist fight. For some it may have been years ago or when they were kids. Fist fights are a scrambling mess of confusion usually. Mostly you end up on the ground. There are no rules. You land a good solid punch and it has no effect. Many punches miss or glance off a shoulder. Your best moves are countered and many just forgotten.
The type of gun fight we're speaking of here is more confusing.
So arbitrarily let's say we have an opportunity to make a head shot and end the aggression right there. If you believe you can make it and the conditions are right I see nothing wrong with taking it.
But most often the conditions and the situation are not right.
Practice at the range and other places is useful for us to get a handle on what we can and cannot do. At what distance can we reliable and on command place 5 rounds center of mass in 2 seconds from the low ready and have each hit land on the target within 6x6" with none missing the target? At what distance can we make an aimed shot under pressure and at speed and do it reliably? When I know that I know some of my limitations.
I cannot make head shots at speed while under pressure and moving at 6 or 7 yards distance on demand. I miss too often. So do most folks. But I can land the shots to the body. So I use that. I do not want to send bullets down range to hit someone I don't want to.
I anticipate that my shots will have no immediate results and I'll have to grapple with the attacker. I anticipate being shot or stabbed. I anticipate these bad things happening to me so that if they don't I can be pleasantly surprised and if they do I won't won't be completely shocked.To increase my chances of survival I'll shoot center of mass, but if I can blow his jaw off I will of course do that.
Back to the fist fight..remember it was fast and confusing and the judo moves
your uncle showed you didn't work or you forget them. So let me suggest something that might be more useful than "head vs. body shots", etc....
Next time you are in a restaurant, bar, doctor's office, mall etc. Envision a man or woman walking in and opening fire on the other side of the room from you. What do you do? Envision a man walks to the table you are at and shoots the person next to you, what do you do? How do you buy time to get a gun out? If you have one. No big speeches he just walks in and surprises you by beginning to shoot. Another thing I find useful is reading reports in the media of shootings in my area and the areas I know and trying to find out what happened. I find these in the real world mental exercises more useful than some other things.
