For CCW, isn't a revolver a very good choice"

[Contenderizer]

The replies above all seem to be right on the mark. The only subject not mentioned is the relative ease of cleaning a revolver as compared to a semi. Proper gun hygiene is mandatory with the semi-auto; a little less so with the wheel gun. But, in either case its a fact of life for all of us, especially so if you carry in an ankle holster. Over the years a revolver can save a lot of time at the cleaning bench.

It also troubles me to think of the number of newbies who purchase a semi-auto and are sent home by the gunshop with a box of cheaper target loads and a second box of ammo for self defense. The newbie may find the target loads to fire and cycle just fine, but I'm guessing they often never fire the pricier self defense loads!
