I know I'll be in the minority regarding this but I simply can not stand the Bisley grip frame. No way, no how would I ever have one. Did I mention I just don't like it?? That would make my choice very simple, I would take my SRH Toklat, it's already a 5" barrel. A bit heavy, but chambered in .454 Casull, which should be more than I will ever need.
