The Smith & Wesson Rear Sight Blade Kit (S&W part no. 191460000) at .126-inch notch width is a factory replacement part built for the universal K, L, and N frame revolver platforms, finished with a white outline around the notch to speed up sight alignment in a variety of lighting conditions compared to a plain black blade. As a genuine factory replacement, it drops in using the same fitment as the original sight it’s replacing, with no additional gunsmithing required. The narrower .126-inch notch width is a common factory specification across S&W’s K, L, and N frame revolvers, giving owners a correct way to replace a worn or damaged sight blade. It’s a straightforward repair part for anyone maintaining a K, L, or N frame revolver.
