Ameriglo’s Trooper Series of handgun sights take much of their design from the sights selected by the Federal Government for duty use. The Trooper Sights offer a traditional three-dot design; the front sight is composed of the ProGlo sight with a green tritium lamp (available with either an orange or LumiGreen outline), and the rear sight features two dots (available with and without tritium) with a subdued square-notch to promote front sight focus.
