I have owned 3 Ruger SBHs but sold/traded them off over time. They were all 44 Magnum caliber. I have 2 Ruger OM Vaquero revolvers now, in 44-40 and 45 Colt. Also 2 Ruger OA revolvers, one has the alloy frame, looks to have been through a couple of wars, but still serviceable, and the newest one is a very nice SS gun.
