1. Energy in and of it's self does not increase or decrease wounding in service pistol calibers. There is no Shock, knockdown, or energy dump. Yes energy is required to penetrate tissue and expand the bullet.
2. Velocity. If a bullet expands and penetrates deep enough at X velocity then X+Y velocity does not make it better. Heavy bullets, 124 or even better 147gr 9mm penetrate almost if not better than some .357 sig.
3. Penetration is the most important thing. A bullet has to penetrate deep enough to reach the vital blood bearing organs at any angle.
4. Bullet expansion is the second most important. A bullet that penetrates deep enough 12" min 18" max, that expands does more damage than a bullet that doesn't expand.
5. Baring an CNS hit blood loss is the only reliable way to stop a bad guy. Energy dump, or the mythical hydrostatic shock are just that myths.
6. Today's hollowpoint designs perform very well in all calibers. The difference in expansion is small between 9mm, .40, and 45. A .45 fmj does not make a .45 hole in tissue, more like .31 cal. Bullet performance is very important.
Finally given good penetration, and bullet expansion the edge always goes to the bullet that expands more.

The statistics and conclusions can be found here.
I was once a caliber snob and thought that there just had to be a "magic bullet" caliber for handguns, but I now agree with Greg Ellifritz's conclusion that when it comes to weak handguns, as compared to rifles anyway, the choice in caliber is largely academic. For me, I will now just worry about factors such as dependability, accuracy and followup speed. Those are likely going to be the factors that mean more to surviving a real-life firefight than which "Wonder Caliber" bullet I am using.

that's good info gglass.
Many years ago I was a .45 auto type of guy only, but 9mm has come a long way in those years and I've recently included it in my safe and on my person.
Maine is typically low in crime, but my rationale is that the folks who are supposed to be protecting us, folks right at the very top, appear to be deliberately putting the country at risk. That has changed the risk and I'm going for round count. I'll probably never need it and I hope I never do. In 35 years of CCW I never have. But if I need it I want enough ammo so that if I can't disengage I'll have tilted the odds in my favor as much as possible. I know I wouldn't want to get hit with any of it. Even when 9mm ammo was pretty much just "fmj like" I wouldn't have wanted to get hit with it. Even less so today.
