The smaller frame .44 Magnums (N-Frame S&W and Blackhawk size Rugers) actually do hold up pretty well for "normal" use and loads.
For shooting 200-400 rounds a year of 250 grain bullets at 1250-1300 fps they will likely last a lifetime. It's when you start shooting thousands of rounds a year or push 300+ grain bullets at 1400+ fps that the smaller frame doesn't hold up as well.
I suspect the 5-shot L-frame revolvers will also do just fine as long as you don't push things too hard.
If you want to experiment with truly heavy .44 loads, you need a revolver designed to handle them......and will have to live with the heavier weight and reduced comfort in carry.
