I haven't considered a 9mm or a 10mm/40 S&W wheelgun with clipped ammunition in this context. What pushes me toward the 45 ACP x revolver combo is the ready availability of the Auto Rim brass. In an ordered and decent world, all revolvers and lever rifles would use rimmed cases.
Order and decency are not hallmarks of our environment, in case you missed that memo. Chaos and drama figure highly in many venues. The USA had approved the 1911-series pistol for its using services, but didn't have enough of them in inventory when Wilson decided that assistance to one side in Europe in 1917 was indicated. (Ah, those Teutonic empire builders--if you don't keep them at your feet, you'll have them at your throat--as they capably proved twice in the 20th Century). Large-frame Colt and S&W revolvers were easily and more quickly adapted to clipped-45 ACP fitment than was re-tooling to make more 1911 pistols as was done 20+ years later for WWII. Clipped 45 ACP ammo remains 'A thing' 103 years later, and 45 Auto Rim brass and cartridges are steady sellers. America loves the 45 ACP. Slow--fat--low pressure--basketball trajectory--none of that matters. The round is accurate and easy to manage (esp. in large-frame wheelguns), and it puts deserving goblins and bridge trolls on their as-pirations pretty reliably, as wartime and street experiences have borne out.
And for our uses as casters, the 45 ACP is by some distance the most lead-friendly autopistol caliber in existence. Yeah, the 32 ACP is accurate and lead-friendly, but did its best work as a marking pellet for adversaries in retreat. Such things fell from lawful favor in recent times, sadly enough. Nowadays, hood rats propelled by all manner of designer racing fuels come at you, often with lethal and/or maiming intent. 45 ACP excels at unplugging their intended atrocities.
