Exactly Agree 100%!!! We here call it "Sissy Forty"
I don't know where "here" is, but I'm going to have to say that it is a bit silly.

9mm is not sissy. .45 is not sissy. .40 is not sissy either. They're all three lethal calibers.

It should be noted that a 180-grain .40 goes about 1000 FPS, which doesn't seem to be blown out of the water by a 185-grain .45 going 1100-1200 FPS.

Speer's ballistic tables for Gold Dot are as follows:

Speer Gold Dot 180-grain .40
Velocity (FPS)
Muzzle - 1025
50 Yards - 956
100 Yards - 902

Energy (foot pounds)
Muzzle - 420
50 Yards - 365
100 Yards - 325


Speer Gold Dot 185-grain .45
Velocity (FPS)
Muzzle - 1050
50 Yards - 955
100 Yards - 886

Energy (foot pounds)
Muzzle - 453
50 Yards - 375
100 Yards - 322

If the .40's tiny increase over the .355-.358 9mm is generally regarded as not being very significant, I can't see why the .45's same margin over the .40 is profound.
