I'm not sure I understand what you are asking.
The Redhawk I shoot simply cannot be compared with a Smith. Or visa/versa. The R'hawk frame is notably stronger. The cylinders are bored at the meatiest portion between the flutes. The lock-up system is much-much stronger, and the list goes on.
Mine is smooth as butter on the action. Beautiful. I shot it competitvely for years. Tens of thousands of rounds. Except for coloring on the stainless it is a no different gun than the day it was new.
There is no comparision. But the choice is yours. If you go for the Smith and do any real amount of shooting, I'll betcha you will be trading off for a Ruger in short order.
