The Smith & Wesson Rear Sight Blade Kit (S&W part no. 191480000) at .160-inch notch width is a factory replacement part built for the universal K, L, and N frame revolver platforms, with a wider notch than the .126 and .146-inch versions for shooters who prefer more visible daylight around their front sight. The white outline framing the notch speeds up sight alignment in varied lighting compared to a plain black blade. As a genuine factory part, it drops in using the same fitment as the original sight it’s replacing, with no additional gunsmithing required. It’s a correct, drop-in way to replace a worn rear sight on a K, L, or N frame revolver.
