XS Sights GLM019P4N Minimalist Night Sight Set Orange Tritium Front/Black Oxide Frame Compatible w/Glock 43X/48

If you carry a Glock 43X or 48, low-light shooting demands sights you can actually see when it matters. The XS Sights GLM019P4N Minimalist Night Sight Set delivers a tritium-powered front sight paired with a blacked-out rear, purpose-built to keep your focus downrange where it belongs. The orange tritium front sight uses XS's Ember Glow Dot Technology—a photoluminescent element that absorbs ambient light and glows in darkness, then gets supercharged by the tritium lamp to shine bright when you need it most. This is a working defensive sight for real carry guns, not a competition accessory.

The minimalist design philosophy here is deliberate. By stripping away the rear tritium and relying on a serrated, blacked-out notch, XS forces your eye to the front sight where accuracy begins. That wide rear notch draws the eye naturally and reduces visual clutter, letting you shoot faster and clearer in close-quarters or dim conditions. The traditional notch-and-post sight picture is instantly familiar to any shooter—no learning curve, no gimmicks.

Made in Fort Worth, Texas with black oxide finish, these sights are built tough for duty use. Installation is straightforward on your 43X or 48, and the standard-height configuration fits most carry setups. If you're serious about being able to shoot your compact carry gun fast and accurately at night, this is the sight set worth running.

Frequently Asked Questions

Will these night sights work on my Glock 43X or 48?

Yes. The XS Sights GLM019P4N is designed specifically for the Glock 43X and Glock 48. Front sight height is 0.215" and rear is 0.300" at standard height.

How does the Ember Glow Dot work in low light?

The front sight features a photoluminescent glow dot that absorbs ambient light during the day and glows in darkness. The tritium element inside the front sight charges and amplifies that glow dot, creating a bright, visible sight picture in very low light or at night.

Why is the rear sight not tritium?

XS designed these as minimalist sights to focus your attention on the front sight, which is where accuracy and speed come from. The blacked-out, non-tritium rear with its wide notch draws your eye forward and reduces visual noise—a deliberate choice for faster, more intuitive shooting.

What's included in the set?

The set includes a tritium front sight with orange Ember Glow Dot and a blacked-out, serrated rear sight, everything needed for installation on a compatible Glock 43X or 48.
