I have large hands, and I don't really like the feel of most of the rubber grips available for N frames - not enough meat to them and they hang down too far, too long.
Last week I bought a '70s vintage Model 29-2 that had some Hogue Monogrips (I think) on it. Fortunately, at the same show a major handgun grip dealer was set up, as well. I made a bee line for him and found a set of original wood grips for the gun, the ones that would have come on the gun.
These original Model 29 grips have become expensive if you can find them, but if I find a set that are in bad shape, I may buy them and round them off. The original factory grips are not perfect either.
I did handle a new Mountain Gun in a gun shop recently. It had some nice wooden grips that fit my hand really well. Don't know if you've seen these yet.
