Something not often mentioned about the Redhawk is that there are not tons of aftermarket grips available. May not be a deal breaker for you if you can find something you like or you like the factory stocks.
As far as strength, as Mackey and other have mentioned it takes a lot of shooting to really wear out an N frame. But other than mainsprings getting light and giving light strikes, I don’t think I ever saw a Redhawk come across my workbench that was “broken”.
I also know two guys who bought both a 45Colt Redhawk and a 454 Super Redhawk. They then disassembled them and swapped the Super’s 454 cylinder into the regular Redhawk. They subsequently shot them for years with no issues. So I doubt you can harm one chambered for 44 Magnum with any halfway sane loads.
