:cb2: I think the Redhawk is one of the finest looking guns on the market. Stronger than the S&W, but the S&W has a much better trigger. The .44 Redhawk I had was amazingly accurate. However, it was the only .44 I have owned that hurt to shoot. That was a major disappointment after wanting one for sooooooo long. Traded it for a .44 Bisley.
I said that the Redhawk was stronger than the 629, and it is a tank, but, unless you are going to shoot nothing but powerhouse loads in it all the time, I wouldn't worry about it. The S&W wouldn't have been such a popular gun for so long if it fell apart so easily.
If you know someone who has a Redhawk who will let you shoot it before you buy it, try it out first if you can. They are both great guns, but the Ruger will cost less. I'd put Hogue Monogrips on the Smith.
It would be hard to go wrong with either gun. They are both high quality firearms.
