Well, I'll go with many of us having different exposure to gun fighting. Cops used to be taught the Weaver stance with precise aiming. That all changed around 1987. The old training was causing a lot of cops to lose gunfights, many after taking rounds to the head because the Weaver stance placed their heads in bad guys' lines of sight. After scientific analyses of gunfights, the farthest cops were taught to shoot was 15 yards. At that distance, only the front sight is used. Closer than 15 yards it was all shoulder point except for 6 yards and less. Then hip point was indicated.
Any hit on a bad guy is a good hit. There is no such thing as a bad hit.
If you want to remain a taxpayer and cannot avoid a gunfight, you must never become an easy target for a bad guy who wants you supine on a fiberglass autopsy gurney. Taking time to aim might well cost you your life. If you want to live and you cannot avoid a gun fight, never make yourself an easy target. Run to a barrier and get behind it. Better, run and keep running until you're out of harm's way.
After you've mastered point shooting, then work on shooting while moving. If you remain stationary, you will be giving a bad guy who wants you dead a very easy target.
What gunfighters of the 19th century might have done has zero application to the 21st century. If Wyatt Earp had access to a 1911A1, do you think he'd of carried a Peacemaker?
Bad guys train. Many have military experience. Rarely will a bad guy do bad things alone. That means that good guys have to scan for bad guys' buddies.
Accuracy is nowhere as important as not getting shot. Precise accuracy is very old school. Now cops are taught to shoot and keep shooting until a bad guy is no longer a threat.
Closing in on two weeks ago I taught a couple friends how to point shoot. One had new sights put on his new CCW handgun. I asked him why he went with new sights. He had no idea of point shooting. So we all went to a nearby indoor range. I went first with an old duty gun. Keep in mind that I haven't point shot since I've retired. My first round hit the 10 ring. The target was about 10 yards distant. Then they tried. Before we left, both had point shooting wired.
The most accurate in a gunfight does not always win, disregarding the fact that it would be extremely difficult to determine the most accurate. I can tell you that the one who doesn't get shot will win. And winning a gunfight is determined by survival. If a good guy dies, he loses. Keep in mind that a human being with his heart destroyed can live another eight seconds, more than enough time to kill a good guy.
Another spurious criterion is number of rounds fired as a metric of gun fighting. When cops fire hundreds of rounds and hit no one, it's a good shooting if cops survive. There is tactical benefit of suppressive or cover fire if it prevents bad guys from shooting at good guys. So when I hear cops fired many magazines, I determine success by their survival. Never die with rounds in your gun.
I highly recommend this book:
https://play.google.com/store/books/...UFlA&gclsrc=ds I'm not sure if calibre Press will sell it to those not in law enforcement. Libraries, especially university libraries will almost assuredly have a copy of it. Were you to read it, it might change your mind about what you thought was right.
Never forget the primary rule of gunfighting: the only certain way of surviving a gunfight is to not get in one. Rule 2: if you cannot avoid, you must not get shot.
It's a wise idea to keep in mind that bad guys train. Many have military experience. Bad guys rarely do bad things alone. That puts a lone good guy at extreme peril. One good guy vs. one bad guy = bad odds for the good guy. Hence, avoid at all costs.
One final point: you have to have a survivor's mindset. You have to be prepared to accept that much of what you now believe might just be wrong...dead wrong.
When I carry a gun for self defense, it's either a .40 S&W or a .45 ACP. I carry heavy-for-caliber bullets in my guns.
