The Tru-Dot Tritium Night Sight for Springfield XD 45 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.
