Today at the range a quick chat with a nice but "know it all" man in his sixties (I guess)
He categorically stated "you cannot compare the 40 to the 45, it is exactly like comparing a 32 ACP or a 380 ACP to a 9mm
I respectfully replied that the energy level of the 40 S&W can match the same figures for some 45 +P loadings while the 9mm does exceed the energy level of a 380 or 32 ACP by ~50% or more and the sectional density of the 40 common loadings is the same of the common 45 offering while the 9mm popular loadings SD significantly exceed the 380 and even more the 32 ACP...
He did look at me puzzled and did not reply....I thought I would share....
