Sight Set, STI - Fixed Tritium

STI manufactures a wide variety of sights for 1911 and 2011-style pistols. The fixed night sight set is designed with a two-dot, "straight-eight" configuration -- rear sight with one tritium insert and front sight with one tritium insert. STI uses Trijicon tritium inserts for the brightest, highest quality night sights available on the market.

The rear sight requires a Novak dovetail cut (65-degree X .459) and the front sight requires a Heini a dovetail cut (60-degree X .300).  Before ordering please confirm that these are the dovetail dimensions on your gun. The front sight is available in two heights: 0.140 designed to fit 3.9" and 4.15" STI slides and 0.175 designed to fit 5" and 6" STI slides.
