Ameriglo GL301 i-Dot Night Sight Set for Glock - Green Tritium LumiGreen Outline Front / Green Tritium Rear

The Ameriglo GL301 i-Dot Sight Set is a tritium-powered night sight set purpose-built for Glock pistols. Built on an all-steel frame with a black finish, the GL301 delivers fast, intuitive sight acquisition in any lighting condition without relying on batteries or any external power source.

The i-Dot configuration pairs a single green tritium dot in the rear sight with a green tritium front lamp framed by a LumiGreen outline, producing a clean dot-over-dot sight picture that speeds up vertical alignment. The rear blade is extended for a longer sight radius, and an undercut face reduces glare to help the shooter pick up the front sight faster under bright light.

Engineered as a direct-fit replacement set, the GL301 fits Glock Gen 1-4 pistols chambered in 9mm, .40 S&W, and .380 ACP, as well as Gen 5 models chambered in 10mm and .45 ACP. It is a versatile upgrade for shooters running any of those Glock variants who want dependable low-light performance for everyday carry, home defense, or range work.
