The Tru-Dot Tritium Night Sight for S&W K, L & N Frames with Front Red Insert from Meprolight is a sight system with glowing dots that are visible under any light condition, including total darkness. When used as a complete set, the three dots align horizontally, forming an easily discernible sight-alignment. The sight can withstand stout recoil, harsh field conditions as well as solvents. This model is compatible with S&W K, L & N frame revolvers with adjustable rear sights and slide-in front sight. It includes an adjustable rear sight and a front sight, both with green dots. The front sight replaces only the blade in S&N ramp-style front sights. It is not compatible with the mountain-gun series.
