Hey, those Combat Magnums are out there, and their owners are by and large not getting rid of them at gun shows. I own four Model 19s, a 4" blue, a 4" nickel, a 6" blue, and a 2.5" blue. I think they are the ideal combination of power, portability, and control. You won't find me giving up any of them soon, that's for sure.
Same goes for the Model 66s, of which I own three - a couple of 2.5" models and a 4".
Whenever I DO see a Combat Magnum at a gun show, I notice that if it's in decent shape, it doesn't last long on the table.
The L-frames are too heavy and bulky compared to the K-frames. With proper care and the correct feeding, the K-frame magnums will serve well and last virtually forever.
