AmeriGlo GL333 Optic Compatible XL Tall Sight Set for Glock - Green Tritium Lumigreen Front & White Outline Rear

The AmeriGlo GL333 is a suppressor-height sight set built for Glock shooters who run optics. Unlike standard iron sights that sit too low behind a mounted red dot or scope, these XL tall sights are engineered to co-witness with most modern optics, giving you both a usable backup aiming solution and a quick point-of-aim reference if your glass fails. They fit all Glock models except the 42 and 43, making them a versatile upgrade for your duty gun, competition rig, or defensive carry piece.

The front sight features green tritium with AmeriGlo's signature LumiGreen paint—a high-visibility compound that glows bright for about 10 minutes after light exposure, then relies on the tritium for low-light and night shooting. The rear sight sports a white outline that frames the glowing front post, giving you a crisp sight picture in daylight and a glowing reference in the dark. That combination of passive glow and tritium phosphorescence means your sights work whether you're shooting at noon or midnight, with or without a flashlight.

Build quality is solid; these are purpose-made for hard use and built to Glock's exacting tolerances. If you're running a taller optic that demands additional clearance above your slide, or if some optics won't quite co-witness with standard tall sights, AmeriGlo offers an even higher "Tall Optic Height" variant—but for most common red-dot setups, the GL333 will sit in the sweet spot. Whether you're training at the range, hunting, or carrying a Glock as your primary, having tritium sights that work in any light is a no-brainer upgrade.
