To me, revolvers are six shooters. Just have no interest in a 7 shot.
As for warranty, the S&W warranty is on guns made after 1989 and technically only to original purchaser. They usually don't ask though. But "lifetime" isn't really lifetime. They no longer make parts for the 3rd gen pistols so if your gun needs service, you will be out of luck.
Now Ruger doesn't give a warranty. What they do give is the best customer service, no questions asked, and no money paid. If they can't fix your out of production gun, they'll either give you a newer model free of charge, or might ask you to pay cost. My buddy sent in his father's Six revolver when his dad died. That revolver fired at least 20,000 357 rounds. It was a bit loose. Ruger brought it back to new specs and even reblued the gun (after asking my buddy). They charged him nothing for the work, and even paid for shipping. And the gun was back to him in less than 3 weeks.
