Bigger holes mean more stopping power. The only drawback of .45ACP over 9mm is more recoil and more weight.
I've shot all 3 rounds. I find at the range they are near equal. Why not carry what you feel most comfortable and accurate with?
I am fairly new to 9mm. If number of rounds were the factor, 22LR with a made with large capacity magazines. After all a 9mm (115gr) round is half the size of .45 ACP (230gr).
I'm sticking with 40SW and .45ACP for self defense. That FNX tactical with 15rd .45ACP is looking better and better.
Here is the excerpt from the 1987 FBI study:
Kinetic energy does not wound. Temporary cavity does not wound. The much discussed “shock” of bullet impact is a fable and “knock down” power is a myth. The critical element is penetration. The bullet must pass through the large, blood bearing organs and be of sufficient diameter to promote rapid bleeding. Penetration less than 12 inches is too little, and, in the words of two of the participants in the 1987 Wound Ballistics Workshop, “too little penetration will get you killed.” Given desirable and reliable penetration, the only way to increase bullet effectiveness is to increase the severity of the wound by increasing the size of hole made by the bullet. Any bullet which will not penetrate through vital organs from less than optimal angles is not acceptable. Of those that will penetrate, the edge is always with the bigger bullet.
This study is why the FBI wanted to replace 9mm with 10mm. In real combat situations statistically they were more likely to be killed than assailants armed with bigger rounds.
The same kind of debate has raged for years in the rifle community. 5.56mm or .308x51. 5.56 puts up volume of fire under 300 yds., and is lighter. .308 is good to 800 yds, penetrates cover, and hits harder.
Carry what you feel comfortable with.
