The only thing the 45 ACP has over the 45 S&W is age and reputation terminally they are very close to each other, the 40 HAs the advantage of fitting into a smaller grip area for Hi Cap pistols, But since you are compairing two pistols of the same make and dimensions the mag Cap is really not an issue. I personally have carried a Glock 21 45ACP for over fourteen years, I could have carried a HI Cap Glock in forty caliber but I chose the Forty Five.So take that for what it is worth. I knew a lot of officers who did not care for the Forty Five because the grip was larger the G21 is slightly larger in the grip than the forty even though they are basicaly the same pistol with slight differances in frame dimensions.
Catridge to catridge you have very near identical terminal ballistics
