Ameriglo GL101 i-Dot Night Sight Set for Glock - Green Tritium White Outline Front / Green Tritium Rear

The Ameriglo GL101 i-Dot Night Sight Set is a purpose-built night sight upgrade for Glock pistols, designed to deliver fast, intuitive sight acquisition in low-light and defensive conditions. Built around a dot-over-dot (vertical) configuration, the i-Dot arrangement places a single tritium dot on the front blade and a corresponding tritium dot on the rear sight so the shooter naturally stacks the two glowing points for a correctly aligned sight picture in the dark.

Both inserts are charged with green tritium for bright, battery-free illumination that lasts for years. The front sight carries a green tritium lamp with a white outline for high-contrast aiming in dim environments, while the rear sight uses a single green tritium lamp to complete the i-Dot pairing. The sights are housed in a rugged steel body finished in black for snag-free carry and long service life under daily use.

The GL101 is engineered for broad Glock compatibility, fitting Glock Gen 1-4 pistols chambered in 9mm, .40 S&W, and .380, as well as Gen 5 pistols in 10mm and .45. This covers popular duty, defensive, and range models including the Glock 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. Whether you carry a Glock 19 on duty, run a competition G34, or train on a Gen 5 G17, the GL101 installs as a direct factory-sight replacement and gives your pistol true 24-hour aiming capability.

Designed as a dedicated pistol night sight, the GL101 is an excellent choice for concealed-carry permit holders, home-defense shooters, and law enforcement professionals who need a confident sight picture from low-light hallways to nighttime range sessions.
