Read what I posted - the Phillipines may have prompted a caliber switch, but .45 didn't do any better.
Everyone needs to remember that we're talking about FMJ. There is no doubt in my mind that .45 JHP is a bit better than 9mm JHP, but FMJ is an entirely different story. Ball is about the ideal shape to go through flesh with the least amount of damage. "Power" doesn't matter when comparing two rounds that poke very clean holes all the way through.
