I have a Super Blackhawk with the 5 1/2 inch barrel and just love it. I think that barrel length is perfect. As far as recoil goes, I have never had a problem with the standard factory grips even with hot loads. Now on the Super Redhawk the shortest barrel length is 7 1/2 inches but you can get a standard Redhawk with a 5 1/2 inch barrel. There is also a world of difference between the two. I also have a Redhawk in 45 Colt with the 5 1/2 inch barrel which I also love as it shoots really good.
