Ameriglo GL5101 i-Dot Night Sight Set for Glock Gen 5 9mm/.40 - Green Tritium White Outline Front / Green Tritium Rear

The Ameriglo GL5101 i-Dot night sight set is built to give you a clear, fast aiming reference on Glock Gen 5 pistols chambered in 9mm/.40. The signature i-Dot configuration pairs a single bright dot over a single rear dot for intuitive vertical sight alignment, making it easy to drive the front post onto the target from the draw or from a ready position.

This set features green tritium vials in both the front and rear sights, with a white outline ring around the front post to boost contrast against darker backgrounds. An extended rear blade adds sight radius, while the undercut rear face cuts glare off the rear element so the front dot reads cleanly in mixed lighting. The sights are housed in a rugged steel sight body finished in black for a low-key, factory-style look on the slide.

The GL5101 is a drop-in replacement set engineered specifically for the Glock 17, 19, 19x, and 26 Gen5 9mm/.40 pistols. Self-illuminated tritium means no batteries or switches to manage; the sights stay readable in low light, no light, and during everyday carry or home-defense duty. A solid choice for shooters who want dependable iron-sight performance out of a compact defensive handgun.

This is a New Ameriglo factory sight set, ready to install.
