And I've seen tests where the .45 out-penetrated the .40 in these stupid phone book tests. But it's obvious you are here to troll and stir the pot. Have fun with that.
And for your information, most 180 gr. .40 rounds leave the barrel at about 1000 fps. 185 gr. .45 rounds leave the barrel at about 1050-1150 fps. But of course, a smaller, slower, lighter round is bound to be more effective.
