Generally, if a 9mm jams during combat, you've got real trouble, because your opponent is still standing. If your 45 jams, it doesn't matter, because you only needed that first shot.
A 9mm, .38, and .357 are the same caliber. You can vary the weights and the velocity and achieve results that cannot physically exceed what that caliber can do. If you shoot it out of a pistol, those limitations are extreme.
We can all point to individual occurrences where a .25 or a .380 dropped a beast or human immediately. The Evans Marshall stuff is hotly contested. The radical statements about the abilities of the 125gr .357 have flooded and polluted the minds of the ignorant. One could say that about the 45acp. In the end, common sense prevails. A heavy bullet of large caliber and moderate velocity is the best we can do against human aggressors.
