Given the arthritis issue maybe an alloy frame gun would be unpleasant. My choices in a new all steel revolver would be the SP-101 or the new production Colt Cobra. I own both, and have carried the SP-101 for over ten years. The SP-101 is probably the better range gun, but the Colt holds six rounds instead of the Rugers five. Both can be had with bobbed hammers if you want something snag free.

If you don’t mind used guns a 2” K frame (Model 10 or 64) or old Colt Detective Special are also good choices.
