If you are going new vs. used .44 I would go the Redhawk 5.5". I had one in .41 Magnum and it is built like a tank. Also had a 7.5" .44 that I took one deer with.

If you want a little bigger take a look at the Ruger .454 Super Redhawk...

Personally I like the grip on the Super Redhawk over the standard Redhawk...
