I wouldn't go near a '73 action in .44 Magnum.
I have those same feelings about a toggle link .44 rem mag. Surely their engineering team has all that figured out. Just don't want to own one as I wonder how it will hold up to a lifetime of full house ammo.
The '73's are the best for cowboy action shooting as they can be set up to run super fast. The '92's are the strongest and my pick for hot loads. They're stronger than the Marlin, IMHO. Ironically they're the worst for CAS, as they're not the best choice for fast cycling. They are COAL sensitive and tend to "stovepipe" and jam when pushed too fast.
