I have a 7 1/2 inch Super Redhawk and a 4 inch 629. Recoil in the Ruger is fine all day, but if you run a couple cylinders through the Smith, you are done with the full power loads. 3" 629? dont think I would shoot it very much. I am not terribly recoil sensative, but I do not enjoy getting beat up. YMMV but its something to think about...
