1911's are on the short list for sure.
Wheel guns, Jerry Miculek has a nice S&W Model 625 in .45ACP, Oorrrrr,...
the .460V loaded, only 5 rounds, but .45LC, .454 Casull, or the .460 all out of the same barrel, is pretty formidable. (speedloaders mandatory)

.
Dirty Harry .44's, pretty darn good there too.
.357's can't be left out either, Model 620 4" barrel with 7 rounds.
But a snub nose .38+P or a 9mm in the "right hands" can make a world of difference.
