As a trauma surgeon, we only get to see the one's that survive long enough to get to the hospital alive. After that, the whole ball of wax really depends on what got hit. Caliber takes a major back seat to the exact structures injured. The majority of the patients I've seen with handgun wounds survive, though I often have to remove part of their intestines or fix some minor bleeding. Big time bleedings usually don't survive to the hospital, though occasionally they do. I have really been surprised over the years to see how well the human body can absorb bullets and not die.
Rifle and shotgun wounds are a WHOLE different class. Those patients usually suffer extensive tissue damage that is much more difficult to deal with. Oh, and as far as "Black Talon" are concerned, all the hollow points seem to do is stop the bullet sooner before it penetrates to deeper structures and causes more damage. It almost makes me want to carry FMJ rather than JHP in my Glock. Almost.
Now I have to qualify this because the majority of the woundings I see do seem to be non-hollow point, and it is possible the hollow point shootings just aren't surviving to the trauma bay. I don't know. But if I had to speculate based on my experience, I suspect there really is much less difference between JHP and FMJ when it comes down to handgun bullets.
I'll still spend the extra buck on decent HP carry ammo nevertheless, but I have learned if you really have to stop an intruder threating your life, a rifle or shotgun does a much better job than a handgun. A handgun is still better than a stick or rock however, and I don't know anyone willing to get shot with one who can avoid it. Bottom line...shot placement is the overwhelming determinant of degree of injury, and handguns don't fire magic bullets that make people just fall over dead. Get training and practice your placement.
