Ameriglo Tritium Night Sights for Glock 43X - Green/White Front Sight

AmeriGlo tritium night sights for Glock 43X deliver reliable target acquisition in low light and darkness, whether you're running them as primary sights or as dependable backup iron to a slide-mounted red dot optic. The Glock 43X is a compact carry platform, and these 1L-height sights are engineered to co-witness properly with common MOS-compatible optics like the Holosun 507K and 407K, the EPS Carry, and Vortex Defender. You get the best of both worlds: a proven night-sight system that lets you shoot through the optic window without obstruction, plus the peace of mind of a mechanical backup if your electronics fail.

The front sight features green tritium vials surrounded by a white LumiGreen outline—a combination that catches ambient light and glows in darkness for fast sight picture acquisition. The rear sight is flat black, a design that minimizes glint and keeps your sight alignment instinctive. For a compact carry gun, these sights strike the right balance: tall enough to co-witness with modern dot optics, but not so tall they snag on holsters or catch on gear during the draw.

AmeriGlo's reputation in the night-sight game is built on consistent, reliable tritium performance over years of field use. These sights are built for shooters who demand confidence in their backup iron sights and want the flexibility to run red dot optics on their Glock MOS slide without sacrificing low-light capability.

Frequently Asked Questions

Will these sights work with my Glock 43X red dot optic?

Yes. These AmeriGlo tritium night sights are sized and cut for Glock MOS slides and are optimized for co-witness with common compact red dot optics including the Holosun 507K, 407K, EPS Carry, and Vortex Defender. You'll be able to shoot through the optic window while using the sights as backup iron.

Do these sights glow without a battery?

Yes. The tritium vials in the front sight emit a self-luminous glow that does not require a battery or external charging. Tritium illumination is passive and continuous, making these sights reliable for low-light and night shooting when electronic optics are not available or preferred.

What is the 1L height and how does it compare to other sizes?

The 1L designation refers to the sight height: 1L has a front sight height of .220" and rear height of .295". This is the entry height in AmeriGlo's lineup. Other taller options (2L, 5L, XL, 2XL, 3XL, 5XL) are available for different applications and optic combinations; the 1L is optimized for MOS slides used with compact red dot optics.

Are these sights compatible with all Glock models or just the 43X?

These sights are manufactured for all Glock MOS slide models. However, this product is specifically listed as Ameriglo Tritium Night Sights for Glock 43X, so we recommend verifying fit with your specific firearm or contacting us to confirm compatibility with other Glock models.
