The new model convertibles are very good quality. Mines a .45 Colt/ACP but same thing. I have the stainless Blackhawk Bisley convertible and it's a beast. They'll definitely out last the person shooting them.
It seems like the convertible model Ruger single actions, be they .357mag/9mm, .45Colt/ACP or .22LR/WMR (I have one of these too), have become extremely popular during this shortage. I hope you find one!
