I've gone back to using the original checkered targets on most of my S&W revolvers but I really like this set of S&W accessory stocks in laminated rosewood, shown here on a 6" Model 66-2.
I've also used them on a Model 686; they are very comfortable, fit my hand well and look very nice at the same time. As indicated by how far they extend past the gun's grip frame, they are slightly longer than the factory stocks, which is good for my somewhat wider hand, but not so much longer that they look out of place.
