Paul Harrell did a comparison between 9mm and .40 S&W in terms of terminal performance and concluded, after several tests, that the .40 was superior to the point where it could actually make the difference between stopping an attacker and failing to stop one. But that has to be balanced against the advantages of the 9mm, e.g., superior controllability and higher capacity.
Did one of his meat targets refuse to stop attacking?
Interesting that he would use the light 115 gr. JHP in the 9mm instead of one of the the more commonly carried 124 gr. or 147 gr. loads. I'd like to see that test with a 147 gr. Fed HST or Speer Gold Dot.
