Self defense calibers should always start with a “4”, such as .40, .44, or .45. . . . .

Perhaps but a lot of people are dead from a cop’s 38 which is pretty similar to 9mm. A lot of soldiers died from 9mm rounds. I don’t think the 9mm lost the wars I think it was allied interdiction of shipping that won the war in Europe both times.

I was joking, sort of: the 9mm didn't lose the war for the Germans but it is barely on par with the .38. The US only adopted the 9mm to make it easier on "smaller, lighter soldiers".

The .45 has a much better record of killing in combat
