I had a Dan Wesson for years and in all that time I'm willing to bet that I didn't put 1/2 a dozen cylinders full in DA. Had to let it go. Couple of years latter with a new and steady job got the opportunity to replace it with a sold to me sight unseen Ruger Supper Blackhawk. The "Blackhawk" turned out to be a Red Hawk. I played with that for a few weeks until I was telling a co-worker about it (another big D.W. fan)he offered to swap a SBH for the RH. I jumped all over that offer and never regretted doing so.
S&W 29/629 are nice revolvers. Every one that I have shot has been accurate and trouble free. I can't see where you would go wrong with ether.
