Ameriglo 4XL Tritium Night Sight Set for Glock Green with Green Outline Front Black Back

The AmeriGlo 4XL Tritium Night Sight Set is purpose-built for Glock pistols that run slide-mounted red dot optics or suppressors. These tritium night sights solve a real problem: when you mount an optic or can on your slide, standard iron sights often sit too low to co-witness properly. The 4XL's elevated sight picture keeps your irons in the fight, giving you a functional backup aiming solution that works alongside your primary optic setup. The tritium lamps glow in low light without batteries, so your sights stay visible whether you're shooting indoors, at dusk, or in a dark venue.

This set features a green tritium front post with a green outline ring for quick target acquisition, paired with a black rear sight. The color combination maximizes contrast and sight tracking in dynamic shooting environments. Whether you're running a competition build, a duty gun, or a hunting pistol with an optic, these sights keep you combat-ready when daylight fades.

AmeriGlo has engineered the 4XL specifically for optic-compatible Glock slides, so you get the height you need without guessing or modding. The tritium technology means zero maintenance—no batteries to replace, no solar panels to keep clean. Once installed, they work night after night, year after year.

Frequently Asked Questions

Will these sight co-witness with my slide-mounted red dot?

Yes. The 4XL's elevated height (.385" front, .480" rear) is specifically designed to co-witness with miniature red dot optics mounted to optic-compatible Glock slides, so your iron sights and optic align properly.

Do I need batteries or charging for the tritium to work?

No. Tritium is self-luminous—it glows on its own without power. The sights will stay visible in darkness for years without any maintenance or batteries.

What Glock models do these fit?

These sights are designed for Glock pistols with optic-compatible cuts on the slide. Verify your specific Glock model has an optic-ready slide before purchasing.

Can I use these sights as my primary aiming system if my optic fails?

Yes. That's the point of tritium night sights on an optic-compatible gun—they serve as a functional backup iron sight system when your red dot goes down.
