I'm now thinking of that kind of setup - and why not?
Because if that M29 doesn't come with the rings, you'll have a challenging time finding a pair. S&W parts department sold out long ago and are not having new ones made.
The rings are based on a design by Millet but standard Millet rings don't fit and can't readily be made to fit. To work, metal needs to be added, not removed. Millet never sold the rings direct to the public, they went thru S&W. AFAIK no other scope ring manufacturer ever made a compatible ring.
Maybe there's a member here with a generous heart and an enormous bucket full of unused S&W rings, gathering dust, who's interested in selling them at reasonable prices. One can hope.

And so, not to be completely guilty of thread drift let me add....
I have a
5-inch M629. It's a -5, so it's nearly identical to the -6 the OP is looking at, but without the lock. Otherwise, it's got the MIM parts and frame mounted firing pin and so on.
Great revolver. I think the N-frame is perfect with a full-lug 5-inch barrel. Not too long, not to short. Seems to balance just right. Took the little seven dollar Weaver base, using the holes that were already drilled and tapped under the rear sight, mounted a 2x Leupold scope on it.
Great combo. Deer hunted with that rig for years. If hunting ain't your bag, would make a great gun for punching paper or busting clay pigeons on a 100 yard rifle range.
