The fail-safe, maintenance-free green Tru-Dot Tritium Front Night Sight from Meprolight does not require any external power source, and provides years of usable illumination in all weather and light conditions. It replaces the stock front iron sight on Glock 10mm, G26, G27, and .45 ACP handguns including G20, G21, G29, G30, G36, and G41.
There is a single dot on the post that easily draws the eye to the pistol's center line for quick target acquisition and tracking. The sight is made from lightweight and durable aluminum with a chip, scratch, and corrosion-resistant anodized finish to stand up to years of use. To further enhance aiming efficiency, use it with the optional rear Tru-Dot sight; available in green, orange, or yellow tritium illumination.
