I like the Ruger Blackhawk with a 4-5/8" barrel for heavy loads. But if I could only have one short 44 mag then I think I would choose my 4 inch blued model 29, with the standard grip.
I do have a .44 mag Model 29 mountain gun, and it's a great carry piece but I don't enjoy shooting it much with full loads. I guess it fine with full loads for an emergency, but the gun serves far better as a 44 special or a loaded down 44 mag. That is where it shines.
The Redhawk is a heck of a gun, but didn't quite work for me, and it's heavier then I want to carry.
