Why does it not shock me that you have one of those?
9mm vs anything;
Modern 9mm loadings are as good as, or better than, almost all of the old school "manstoppers", including the much vaunted 125gr .357mag, 158gr LSWCHP .38special "FBI" load, and any of the factory .44 specials and .45 Colt loads a copper would have carried back then.
But that still doesn't irrelevate (Yes, that is too a word, I just invented it....) revolvers nowadays.
