9mm or 40 cal
#11

I carry pistols chambered in both cartridges mentioned. I am tempted to get rid of my 40 and stick to 9mm just to keep one type of ammunition for this type of pistol.
My wife shoots a 9mm and has no interest in a 40 so the decision will be an easy one when the time comes.

Looks like you've figured out the pistols you're getting. I've carried the 9mm and .40 both on duty and off. 40's shoot a little hotter but are still pretty manageable if you practice. Ballistically, you get a little more with a .40 but shot placement is still where it counts. Something else to consider is if your wife is already getting a 9mm, you getting a 9mm also means ammo commonality and maybe one less set of reloading dies, etc. Either way, you won't go wrong. Just make sure you both practice for optimum results.

I work in a large trauma hospital in Chicago, and have treated many, many gunshot victims. The vast majority of them were shot with handguns, and the vast majority of them survived, regardless of caliber - I've seen people shot with .22's, .38 special, 9mm, .40, .45 and others. I distinctly remember one gangbanger that was shot in the face at point blank range with a .45 and survived - the bullet did not penetrate the brain.
The majority of them that did not survive were shot through the brain, although occasionally death was due to a bullet hitting the heart or a major artery.
The point of a handgun for self-defense is to incapacitate the bad guy, or make him hurt badly enough that he stops trying to hurt you. When you look at it this way, a larger caliber is generally better than a smaller one - greater chance to inflict damage. But the difference in damage between say a 9mm and a .45 is not all that big.
If you want to stop someone in their tracks/drop them dead with a handgun, you generally need to hit the brain, heart or spinal cord. Otherwise, use a shotgun or rifle - either one is much more devastating than a handgun, regardless of the caliber.
Because of the lack of power in a handgun, shot placement is very important, so choosing a handgun/caliber that you can shoot well with is more important IMO than just getting the biggest caliber possible. Personally, I would choose the largest caliber that you can shoot accurately and handle well, but that also allows for the largest magazine capacity possible so you can increase your chances of hitting/incapacitating the bad guy.
Another reason why a lot of thugs with gunshot wounds survive, is that for some reason gangbangers use FMJ bullets the vast majority of the time IME. I'm not sure why - maybe cheaper and easier to get? FMJ bullets tend to zip through the target with less tissue damage than a hollowpoint.
