Right now there seems to be a market nitch for revolvers again. It seems to me the desire for a 357 mag and 41mag seems to be hot right now. The want for a 44mag will never change. The shorter barrels.
I see Ruger just came out with a 5 shot .44 Special on the GP 100 frame with a short barrel, 3"? With Colt reintroducing the Cobra, and Kimber making a revolver, there does appear to be sea change and resurgence of interest in wheel guns. Good.
