I only have a .357 Redhawk, no .44 yet but I want one badly. My .357 is a great gun, probably the strongest .357 on the planet, and the RH .44's are known to be the most durable .44 Magnums ever made, maybe next to the Super Redhawk. There's a reason the handload manuals have "Ruger only" loads, and not "S&W only".
If you're having misfires in your RH I would be calling Ruger for a return label and not accept it back until it works 100%.
I never liked the look of the standard Redhawk with the scope mounts on the barrel.......if you're looking to scope a DA Ruger you need a Super Redhawk, a scope on a SRH is like a hand in a glove, those things are made to be scoped. I turned away a blue 7.5" .44 Redhawk because I didn't want the ugly scope mounts on the barrel.
I do have a S&W 29, an early 70's vintage. It's a gorgeous gun, a masterpiece, really. The action is perfect, it feels perfect in the hand, and it is a relic from when S&W employed skilled craftsman and master assemblers, instead of CNC machine operators. Truth be told I stumbled on it in my local gun shop for a price too good to walk away from, and I'm not about to leave the most famous revolver in the world, Dirty Harry Callahan's 6.5" S&W Model 29 .44 Magnum, the most powerful handgun in the world that will take your head clean off, laying in a gun shop for $450!
I shoot all of my Rugers and S&W's, but the 29 was almost new when I got it, and me and my Dad only took it to the range maybe 3 times for a handful of rounds. It's more of a "cool factor" piece than something I bought to shoot a bunch of rounds through. It's tight as a drum and I see no need to use it as a "shooter"........I have a .44 Super Redhawk and will get a 7.5" Redhawk to take the duties as shooters 8)
If you're looking for a heavy shooter, to run 1,000's upon 1,000' of hot .44 rounds through, the Redhawk and SRH is the only way to go. The S&W 29's are more collector pieces and "status guns" these days, unless you find a beater or a basket case, in which case you'll have to spend $ to get it back in shooting shape anyway. I have seen 29's that have been shot too loose to ever bring back, without a complete overhaul.
The S&W 629 and "Classic" 29 look good, but for over $700, you're still not getting a gun as durable as a Redhawk.
