Some folks never left revolvers, and the wheelgun is the perfect tool for some applications. If I'm wandering in the timber and want a powerful handgun filled with snake shot, a revolver is my only choice. In that same handgun, I cal load heavy, full house loads or I can load powderpuff plinking loads. It's hard to beat the versatility of a good revolver.
New features? Not so much. My revolvers were all made in the last century, many before 1980. I like my autos too, but they're a different tool for a different job. Just like I have several hammers, from a tiny tack-hammer to a 16 pound maul, it's all about having the right tool for the job.
