For Smith and Wesson revolvers. Fits S&W models 629, 686, 586, 627, 66, 67, 696, 17, 19, 657, 610, 625, 29, 27 and 50 caliber.
Black sight blade. The sight is adjustable in height and sideways. Black base on the sight to harmonize with the color of e.g. a black S&W.
The sight only fits frames that have two holes for the screws. Old frames with one screw hole that holds the sight are not possible (must be modified by drilling a new hole in the frame and threading so that both screws can hold the sight).
