Vintage 1950's Wondersight ad
Wondersight may be fitted to the new "classic" model Smith and Wesson revolvers with the upper side plate screw such as the 22-4. The sight bottoms out approximately 1/8" higher than the original sight notch due to the modern heavier frame limiting the Wondersight travel and may require the installation of a taller front sight. The Wondersight fit may be lowered slightly on the newer firearms with some minor modification to the sight.
