For defense, the best rule of thumb is keep dumping shots COM until it's no longer a threat. Thinking you'll be able to make a headshot on a roughly 3" moving target under stress is unrealistic. In the time it takes to aim more carefully for the headshot, you could have poked 3-4 more holes COM. The COM shots are more likely to hit(bigger target), sending fewer liabilities downrange. Also, skull increases odds of deflection on even a good shot. 3-4 more pulls increases odds of hitting heart, lungs, spine or pelvis...which is better than changing point of aim to probably miss a target that may deflect even with a relatively solid hit.
For defense, if u want a drill....get good at drawing and dumping a mag, keeping all shots inside of a 5" circle from 5 yds. Once you can do that, speed up the cadence and work at that faster cadencE until all shots are back inside that circle, then speed up again.......this is of course for after mastering the more important skills of grip, sight alignment, breathing control and trigger pull.
That's my basic take on it as well.
The head is a very small, very mobile target. A skilled shooter might be able to register a good hit on a target like that, but it's unlikely and even then it will probably require several shots. Even non-lethal hits on center of mass can temporarily slow an attacker. They may, they may not. But they have a better chance than an outright miss at the head.
Wait, you guys don't think someone should do the failure drill at all? Not just in the sense of practicing, but in a defensive situation?
My impression was that with handguns, unless you do sufficient damage to the spine shots to center of mass, even very lethal ones, are going to take a while to incapacitate someone if shock or the desire to have you call the hospital for them doesn't halt them. Even if you put one through the heart you're going to be in for a tussle for perhaps longer than you'd like. Putting more rounds through a already perforated lung aren't going to speed things up all that much.
This is why you continue to fire until the threat is eliminated. There is no magic number for how many rounds a human can survive and for how long. Fire until the threat has been suppressed. If you are switching your point of aim during the engagement you are entering a whole new variable in the likelihood of scoring a valid, incapacitating hit. Do you know the average shot:hit ratio for law enforcement? It hovers right around 17:1 for most agencies. That's right, for every seventeen rounds fired in self defense only one hit, on average. Now there are clearly many variables in that number, but it does give one a good idea that they are most likely going to miss with more shots than hit. Why increase your chances by moving to a harder-to-hit target?
Aim for center of mass, fire until the fight is over. Maybe you fire once, miss, and the guy puts his hands up and calls it over and done... maybe you fire fifteen times and he finally goes down. You won't know until you are there and between the adrenaline and the chaos you will revert to your most basic motor skills. Concentrate on reinforcing basic skills until you can do them as easily as blinking.
Anyone who has had a gun pointed at them in anger will tell you all training goes out the window instantly. All those Rambo, ninja drills are gone. There are hard cases of police officers who trained to unholster, fire two rounds, and assess the target who were killed in the line of duty when they unholstered, fired two rounds, and stopped to assess the target WHO WAS STILL SHOOTING BACK.
Body armor seems a bit high end for a robbery gone wrong, but a BTK type psyco might spring for it. And a phonebook in the jacket is affordable for anybody.
If you're fighting a bad guy with body armor you've already lost, at least in a home defense scenario. This goes into my "tiger" theory of home defense. If the guy has planned thoroughly enough to attack your house like some sort of Splinter Cell agent you will be dead before you ever get in the fight. It's about the same as walking into your living room and finding a hungry tiger. You lost, time to make your peace.
EDIT: Upon further thought if you're really expecting to fight some wild Splinter Cell bad guy with body armor and phonebook SAPI plates stick with a rifle. Even an intermediate caliber like a 5.56 will zip through soft armor like it wasn't there. In fact a 5.56 platform is actually a fantastic home defense weapon.
