I think that in 2 categories revolvers really rule:
1) Hammerless 5 shot j frames as pocket/ backup guns, a very good tool in a contact range fight.
2) Magnums for large animals, Bowen .500 , .475 Linebaugh Redhawks etc... Ross Seyfried wrote much about this.
For defense against packs of feral people or dogs I would rather have a high capacity auto of at least 9mm. Currently I am shooting .45 and 9mm Glocks and HK45 Lem , HK P30 LEM.
Tom Givens stated that his change from 1911 to GL35 was that Memphis was a 3 bad guy town and a 1911 was a 2 bad guy pistol.
