Which was part of the argument in the 90s as well, particularly if you think about what was even available in terms of semi-auto handguns at the time. The argument, I believe, was that a fullsize 1911 was about the same size as a Glock 17, and in that case you "might as well" have 9 rounds of .45 as 11 rounds of 9mm. it wasn't even about what you shoot better, but strictly what was even available.
