i like both.
1)-the 629 can loosen the ejector rod under the recoil of several rounds;say at the range. when this happens it binds the cylinder in the frame. a screw driver or other small impliment must be used to push the top of the ejector rod"in" while you push the cylinder release,to drop the cylinder. my gun was a 629 classic 5".
S&W's are great for finding the gun that fits you. triggers are generally good,fit and finish varies.
2)-make sure the redhawk grip is'nt too large for your hand. the length of pull was too deep for my hand for optimum handling. i disagree with those who rate the S&W better. the redhawk has better sights that are easily interchangable, the revolver can easily be broken down for detail cleaning, mine had a fine trigger,and the gun is simple and tough; you don't have to baby it like a S&W. rugers are more consistent from a fit & finish stand point.
i currently own a ruger super redhawk which has a much better grip for my hand size. i have recently contemplated getting a S&W again. if i trade in my SRH, it's not because i don't like the revolver. i simply refuse to collect more firearms than i need/want. as a non-hunter, i draw the line at 3 firearms.
