The Meprolight Tru-Dot Tritium Night Sight Set (Meprolight part no. 0198103101) fits Armscor and Rock Island Tac 1911 Government-frame pistols with a self-illuminated, three-dot aiming system from Meprolight. A green tritium front dot with a white outline pairs with green tritium rear dots for a sight picture that reads the same at a lit range or in a dark room. Built as a direct replacement for the factory sights, installation calls for only minor fitting. For a 1911 carried for defense, a fixed set of night sights is one of the highest-value upgrades available.
