The Tru-Dot Tritium Night Sights for S&W Sigma from Meprolight is a sight system with glowing dots that are visible under poor light conditions, including total darkness. When used as a complete set (together with the separately available front sight), the three dots align horizontally, forming an easily discernible sight picture. The sight can withstand stout recoil, harsh field conditions as well as solvents. This model is compatible with S&W Sigma and includes a rear sight only with green dots.
