I bought a 2", RB, M&P recently. When I first saw it I was a bit disappointed because I thought it had a modern set of Altamont "Rosewood" (plywood) grips on it. It turns out they were the original S&W solid walnut grips that had taken on a more reddish patina over the past 66 years. That was the icing on the cake.

Not what your original post was about, but the wood can certainly push you over the break point when deciding whether to get it or not.
