BullTaco, as stated above, it kinda depends on for what use you intend, as to barrel length.
If it's just for a "packin'"gun, or perhaps a self defense gun, then a 4" barrel is desirable. If you intend to hunt, in addition to the other uses, I'd advise a 6" barrel.
Reloading opens up a whole new, wonderful field for the .41 Magnum. Nevertheless, there is some very good factory ammo out there.
I have a S&W 57 6" nickel revolver (just like .41Dave's, and a Ruger Blackhawk 4 5/8 bbl., .41 Mag. Years ago, I had Deacon Deeson make a custom pair of grips for my Model 57 on Skeeter Skelton's Bear Hug style. Handles very, very nicely.
I also have a Marlin 1894S lever action in .41 Mag., and that combo is really nice out in the field. I've killed both deer and Black bear with the .41 Mag. (Plus coyotes and ground squirrels.)
.41Dave, those are some very nice pieces. I am at the moment, looking for a 57 .41 Mag Mountain Gun just like the one in your picture. (Wish me luck!)
