What battousai said.
Except for one thing...and this is a bit theoretical, as my trajectory calculator says it will work, but I don't know which, if any, sights or scopes will allow for enough adjustment.
If you zero at 25 yards, there is a ton of drop for the 45 at 100 yards, like 12-20 inches, depending on the load.
But IF you can zero the .45 at 100 yards, it will only be a maximum of 4.5 inches high at around 35-40 yards, while still only 2.5" high at most closer SD ranges. Aimed center mass, that is still good enough for SD, while allowing you to simply put your sights on a 100 yard target, and shoot.
But the .40 will do that as well, and probably better.

Not anything to do with me,...but SWAGA referred me to it...and it is pretty funny: The Ballad of Ajole
