I have a 4" Redhawk. I used to own a 4" Taurus .44 mag, and the Redhawk is definitely heavier and tames the recoil a bit more with the same loads.
I will say, if you're looking for range gun, why not look at a longer barrel? That will absorb even more recoil and be more pleasant to shoot at the range. Magnums love longer barrels, as it gives the powder a chance to burn, and really kick up the velocity.
That said I really do like my 4" RH. It has a lightened mainspring in it, and its double action pull is right up there with some of my nice, older S&Ws. Because of the trigger system the SA pull is never going to be as light, but really, it's good enough as it is. Not every gun can or should have the "2.5lb glass rod" action of a tuned 1911.
