The Ruger Redhawk has a smaller frame of more conventional Sellout & Wesson design with respect to how the grips are attached. The Super Redhawk has a spur grip more like the SP-101 and GP-100 of the same family. Because of the grip style of the Redhawk, It's a bit more painful to shoot if you ask me. Also, the frame is not as strong and the barrel doesn't thread into as much of the frame. You can mount the scope further back on a Super Redhawk also. The only advantage I can see to the Barrel Mounting is that you can retrofit any Ruger with an integral Mount by just fitting a new barrel.
