Yup, you got it. And the FBI actually settled on the 10mm as the ideal round... and then "whiny little people" got them to water it down to .40 S&W. The bigger slower bullets they like are really for subsonic work with suppressors. If you are shooting and you need quiet, the bigger heavier .45 has the advantage over a subsonic 10mm except in capacity.
