I do agree that either makes you undergunned against someone with an AR, but you stand a better chance with a tuned 1911. If you are limited to a handgun and a long shot is on the table, that's the one.
I disagree. If one KNOWS longer than normal pistol combat ranges will be required, revolvers rule the day for accurate aimed fire. That's what you see used on "sillywet" steel target ranges.
If facing a long arm at distance with a combat pistol, one best be able to supply a high enough rate of fire to somewhat suppress or negatively influence the rifleman's aimed fire. Going at each other with aimed fire will result in a quick loss for the pistol shooter. One best do what they can to prevent the rifleman from well aimed fire. Not "spray and pray" but having plenty of rounds of higher velocity ammo on board is a good thing. Well, maybe the "pray" part anyhow...
