I've been saving up for one of those with the 6'' barrel. The trigger on them is damn smooth.
To answer the kiwi's question; they are useful for when you are hiking in brown bear territory. I have a .357 that I carry when hiking when it's just black bears and mountain lions. But the .44 is good for being more effective in killing smaller beasts as well. My dad's detective friend used to carry a Model 29 around when the Dirty Harry movies came out, when the .38 special bullets bounced off an assailants windshield, his .44 mag punched through. Plus, they are just damn fun to own and shoot.
