Ameriglo Tritium Front Sight Features The Ameriglo Tritium Front Sight uses a tritium-illuminated insert to give shooters a consistently visible aiming point whether on the range in daylight or during a low light defensive encounter. The green tritium vial is surrounded by a black outline a configuration chosen to maximize contrast against the sight body and make the front post easy to pick up quickly under stress. Because tritium is self-illuminating the sight requires no battery no charging and no external light source to stay visible which means it is always ready the moment the pistol is drawn. This makes it a dependable option for concealed carry duty use and home defense pistols that need to perform in unpredictable lighting. Built to fit all Glock models this front sight is a simple drop-in upgrade for shooters looking to replace a worn or dim factory sight with a brighter more durable tritium unit. The .165 inch height and .125 inch width keep the sight within factory dimensions helping maintain proper sight alignment and point of impact after installation. A black sight body is included to keep the overall look clean while the green insert draws the eye to the front sight first. Ameriglo built its reputation on tritium sight technology and this front sight brings that same durability and visibility to a straightforward Glock upgrade available for sale at GrabAGun.
