I have 4" and 6.5" M29s, as well as M57 with 8-3/8" barrel, and I've fired very little factory ammo through any of them, so my observations may not be the most relevant for you. However, if you're handloading you can do pretty much anything you want with recoil mitigation. If you're shooting strictly factory ammo, I feel the .41 mag certainly offers less recoil than full power .44 mag ammo, but with the .44 you have the option to shoot .44 Specials as well, including some pretty mild cowboy action stuff. Plus, .44 factory ammo is considerably less expensive than .41.
