The FBI tested the 9mm, .40 and .45 rounds for stopping power.

They concluded that a hit in the torso from a .40 supersonic rounbd had a 100% probability of incapaciting a man, while for the .40 subsonic and .45 rounds it was 90% .

I don't remember precisely what the number was for the 9mm, but I think it was slightly less than 80%.

I'd like to see a link to that 'study'. No pistol round in history has a 100% probability of 'incapacitating' anyone.

I am not familiar with this info, and have NEVER heard of any handgun combination scoring 100% in any caliber. Can you provide any source info?

Makes you wonder how they test such a statistic.

Impossible. There are two ways to incapacite a person. One is a hit to the central nervous system, i.e. spinal cord/brain. The second is through suffocation, i.e. blood loss. As for the first, any well placed shot from any firearm will do. This is the ONLY way to 'drop' a person.

As for the second, no matter what someone is hit with, it will take time for them to bleed out. Yes, some rounds work better than others, but nothing is going to create a 100% chance of incapacitation.
