Actually, I think each has its advantages and its place.
Unfortunately, the revolver's advantages have been overshadowed by the pistol for all the above reasons.
In particular, IMHO, a revolver is a superior HD handgun. It's simpler and more reliable. Assuming proper maintenance, I know those first six shots will go bang. I can also leave one loaded in a secure location for years on end and know it will go bang. Having been on the wrong end of a handgun more than once, I can say with some authority that an N frame is unbelievaby intimidating...Big holes, about five of 'em visible, four with nasty looking bullets in plain sight.
With respect to reloads, after some practice, I can reload my 625 with moonclips almost as fast as a 1911. Most revolvers can be modified for moonclips for less than $100 -- the cost of four or five pistol magazines.
Except for J frames, however, I think the CC advantage pretty much goes to the pistol. They're thinner and lighter. And some of them will handle dirt better than a revolver will. Some of can also shoot a pistol faster than a revolver. At least I can. I am somewhat more accurate with a revolver, though.
