I was commenting specifically on the thought that a .45 was going to knock a person wearing body armor "on their azz". The physics just doesn't work out that way. No pistol round is going to knock a person weighing over 100 lbs down unless it would also knock the shooter down.
Handgun bullets work on stopping people by either hitting the central nervous system or through blood loss. On that second point you could have a valid reason to select a larger bullet, but the diameter of the bullet isn't the only factor contributing to blood loss.
So, I hope you didn't take the point I was trying to make as something more than the fact that a .45 will not knock someone down espescially if it doesn't make it's way into the body. It may make them think twice about what their doing, but if it would, then most other handguns delivering similar energy would as well. If a body armor clad badguy does fall over from a pistol shot it is probably from fear, not physics.
I carry .45s and 9mms interchangeably.
