I think launching the 480 in the double action platform is what killed it. Super Redhawks are fine guns. I have one. Its HD, accurate, and with double action Im more likely to stop a bear attack, & it's setup with solid scope mounts right from the factory. OK great, BUT.... Single actions (Blackhawk & SBH), have less moving pieces for durability, are more packable, totally different grip, alot less money, more customizable, shorter barrel lengths for us that perfer that, setup without ugly built in-scope mounts (for those of us that never intend to scope a handgun), think about how many of us just collect single action rugers for all of those reasons ... many would buy one just because "we don't have one in that caliber", and the list continues. In short the single actions are more popular, why not try it there first?
I think Ruger got spooked by the big S&W's ... They put their big bore double action against S&W's big bore double action, and got embarrassed! Size does matter! Hey that's fine, put it in a smaller single action platform where you dont have any direct compition ( I know -Freedom Arms & BFRs, but I dont consider these competion due to price and availability), and the "little 480" will shine, due to it's lack of pressure and recoil! I don't think I would want to shoot anything bigger than a 480 unless a dare followed by $ was offered!
Im sure they would sell a million of them.
