I'd say sure, if a person is already proficient with a single action revolver, then sure, he should carry it instead of carrying a higher-cap bottom feeder for self defense, if he's not proficient with the bottom feeder.
But, I think the point of many of the posters here, the ones who advocate semiauto pistols for self defense, is that there is a point at which a person is devoid of any proficiency with any gun at all, (at the very beginning of his gun training experiences, before he has committed to any type of gun) and, at that point, if that person were to begin down the road of becoming proficient with a firearm, then at that point, he'd be better advised to choose a semiauto to become proficient with then a single action revolver to become proficient with, if self defense were the name of the game.
It's not logical to compare a guy who's a single action whiz to a non-trained Glock toter. You gotta compare apples to apples and oranges to oranges. At the beginning, before a person has become accustomed to any handgun, and if self defense is his purpose for carrying the gun, then the proven better tool to train with is the semiauto. That's why it's the choice of professionals everywhere.
I must say, however, that shooting needs germaine to working a 100 acre farm are distinctly different than those in an urban environment, and, I can see choosing a single action revolver there, even in the beginning, because self defense isn't the only game in town on such a piece of land, as CraigC illustrated.

Sorry about the bad luck with the Hombre. Check to see if the Cylinder pin is inserted properly; sometimes if it's not exactly in it's proper place, it will prevent the cylinder from turning.
