Trijicon HD Night Sight Set for Glock 42/43/43X/48 - Steel Matte 3-Dot Tritium Green with Front Dot Outline

The Trijicon HD Night Sight Set for Glock 42/43/43X/48 brings purpose-built low-light performance to one of the most popular compact and subcompact platforms in America. Built for shooters who need fast front sight acquisition in variable lighting—whether you're training at dusk, hunting in dim conditions, or handling a defensive scenario—these steel matte sights combine tritium self-illumination with photoluminescent paint to keep your sight picture sharp when ambient light fades.

The HD design prioritizes what matters in real shooting: the front sight features a taller blade with an aiming point ringed in photoluminescent paint (green tritium with outline as specified), while the rear sight sports a wider U-shaped notch outlined in black. That geometry cuts transition time—your eye locks onto the front dot faster, even as light conditions shift. The rear sight also incorporates a steeply hooked front surface, a practical detail that lets you run the slide one-handed in an emergency if needed.

These are tritium sights, meaning they produce their own light through sealed gas tubes—no battery required, no charge needed. The green tritium lamps carry a 12-year warranty from manufacture date, giving you years of reliable glow in darkness. Steel construction and matte finish keep weight minimal and glare controlled, making them equally at home on a carry gun or a dedicated training platform.

Frequently Asked Questions

Will these Trijicon HD sights work on my Glock 42, 43, 43X, or 48?

Yes. This sight set is engineered for those four Glock platforms. If you own a different Glock model, you'll need a different sight set.

Do I need batteries or charging for these night sights?

No. Tritium sights are self-illuminating—the sealed gas tubes produce light without power or maintenance. They glow continuously in darkness and dim light, and they'll keep working for years with zero battery dependence.

What's the difference between the tritium glow and the photoluminescent paint?

The green tritium is always on—it glows in complete darkness. The photoluminescent paint ring around the front sight aiming point absorbs ambient light and glows brighter in twilight and transitional conditions. Together, they give you a sight picture across the full spectrum from bright day to pitch black.

Can I use the rear sight for one-handed operation?

Yes. The front surface of the rear sight features a steeply hooked design that allows you to rack the slide one-handed against a belt, holster, or solid object if needed—a practical feature for defensive or emergency scenarios.
