Ameriglo Tritium 2-Dot Rear Handgun Sight for Glock Yellow with White Front

The AmeriGlo Tritium 2-Dot Rear Handgun Sight for Glock with yellow tritium and white outline front is a proven night sight system purpose-built for Glock pistols across all models. This rear sight configuration delivers rapid low-light target acquisition without requiring external light sources, making it the choice for duty carry, off-duty backup, and training scenarios where ambient light is unreliable or absent.

The sight features .276-inch height with a .165-inch square notch—dimensions that position the sight picture at factory Glock height specifications, ensuring zero compatibility with factory holsters and accessories without modification. AmeriGlo's tritium technology self-illuminates via radioactive decay, eliminating battery dependency and maintaining sight visibility indefinitely in total darkness. The yellow tritium rear dot paired with a white front sight design creates a high-contrast sight picture under both daylight and low-light conditions, reducing eye strain during extended shooting sessions and accelerating target transitions on multiple targets.

Law enforcement officers, armed security professionals, and serious sport shooters rely on tritium sights when mission requirements demand immediate target engagement in variable lighting. Unlike fiber-optic or LED alternatives, tritium sights function without maintenance or power management—a critical advantage for duty weapons that may sit undeployed for months between use. The white outline around the tritium dots aids daylight sight picture consistency and prevents tritium degradation visibility loss from impacting practical accuracy.

This sight fits all Glock models and dimensions, providing flexibility across platforms from compact duty pistols to full-size competition and training variants. Installation requires professional gunsmith services or advanced armorer-level technical knowledge; improper installation risks sight retention under recoil and compromised safety. AmeriGlo tritium sights are manufactured to withstand standard pressure hand loads and maintain zero under extended duty use and training cycles.
