Redf150 - I have a 4" S&W Mountain Gun configuration revolver - it started life as a 6.5" dirty harry Model 29-2 and I had the S&W Performance Center install the shorter bbl. I don't shoot full house loads all the time. I shoot them in preparation for hunting season - the rest of the time I'm kickin' cans with lighter loads. I still use the magnum cases but loaded lighter than full house.
I love mine. It carries very easily, is easy to shoot and handle, and I don't think or feel it recoils any worse than any other magnum with a short bbl. I limit my shots to 50 yds, unless I have such a good sight picture that I know I can place the bullet accurately at a longer distance. I know what the 44 magnum is capable of, and what I am capable of doing with it, and stay within those limitations. In that light the 4" bbl serves me well, and when I take a shot at a whitetail, or something else, I hardly notice it going off. To be honest, I think the recoil is slightly more than with my 3.5" 357, but hardly noticeably more, from my perspective. HTH. Mikey.
