Many reports of .45 ACP ball knocking down lightly-built japs during the Pacific.

One well documented case, though it may have occurred later in Vietnam I can’t remember, was one Marine or Soldier was in a rice patty (yeah I think it was Vietnam now) and was ambushed by three enemy. He pulled his Colt’s M1911A1 .45 and with a single shot each, dropped each enemy with authoritude.

He later said that if he were armed with a lesser gun, namely a 9mm, he would have been dead. Time has shown in theater that 9mm ball has next to 0 stopping power on an aggressive indoctrinated foe, while the .45 even with hardball will drop them almost every time.

And as far as modern hollowpoints go, the same advances touted for the 9mm have also occurred with the mighty .45 Automatic Colt’s Pistol. True you do give up some capacity vs. a 9mm gun, but with so many failures to stop with the “Tiny-9” it more than makes up for it in sheer knock-down dropping factor.

Just my $0.02.
