Ameriglo GL305 i-Dot Night Sight Set for Glock 42/43/43X/48 - Green Tritium LumiGreen Outline Front / Green Tritium Rear

Upgrade your Glock 42, 43, 43X, or 48 with the Ameriglo GL305 i-Dot Night Sight Set (also fits MOS variants), a purpose-built low-light sighting solution built around Ameriglo's signature i-Dot configuration.

The i-Dot layout replaces the conventional three-dot pattern with a dot-over-dot design - the front sight's tritium element aligns vertically with a single tritium dot on the rear sight for fast, intuitive sight alignment. The front sight features a green tritium lamp framed by a LumiGreen outline for quick low-light acquisition, while the rear carries a single green tritium dot. Tritium vials glow continuously with no battery or external light source required.

Both front and rear elements are built around a steel housing in a black finish, sized and contoured to drop into the factory dovetails of your Glock 42, 43, 43X, or 48. The rear sight is extended for an increased sight radius and features a glare-reducing undercut on the rear face to cut distracting reflections during presentation.

Whether for defensive carry, home defense, or any low-light pistol shooting, the GL305 delivers reliable, fast aiming when you need it most.
