Let me say that I love revolvers, and I think the craftsmanship of them in most is beautiful, and a kind harder to match in autos. I used to carry an LCR, and a 3 inch model 10.
The sad fact is that there's no REASON to carry a revolver over a semi. An auto can be made to weigh less, be smaller, carry better in shape, reload more quickly, hold more ammo and be at LEAST as powerful as many revolvers. In fact, power, depending on your caliber choice, is about the only advantage that a revolver offers. Maybe a slight edge in reliability, but technology these days makes that an almost nonexistent issue when you've made sure your auto is reliable. The last thing you want to do is carry a gun for your whole life, and one day need to actually fire it, and have it not be enough. I don't want to be lying there on the ground one day bleeding to death thinking of the irony that if I'd had a couple more shots, this wouldn't be happening.
Like the Glock vs 1911 debate, it's more a matter of hanging on to the old school way. And I say this with a love of revolvers.
