I think they haven't done it so far, was because they thought it would hurt their SRH sales. A SA .480 Bisley would be stronger, more reliable, and cheaper. Plus there's a bunch of us SA folks that would rather have, and pay for, a custom Gary Reeder (et al.) SA than a DA in that caliber. If Ruger is smart, they'll make one soon. They are missing sales, because if they won't do it (they can)--others will continue to do so. (With a Ruger product!)
