The TruGlo Tritium X night sight for Glock 42/43 is purpose-built for shooters who need reliable sight acquisition in low light and darkness. Whether you carry a compact Glock daily or train regularly at the range, these sights combine Swiss tritium lamps with a steel construction designed to handle hard use and neglect. The green tritium paired with a white front dot outline gives you fast target acquisition in daylight and a glowing reference point when the sun goes down—no batteries, no charging, no complications.
Tritium sights work on a simple principle: sealed glass vials filled with tritium gas emit a constant, self-powered glow that requires no activation or external light source. That makes them ideal for defensive shooting, hunting in dim conditions, or anyone who wants night-capable sights without the weight and cost of electronic optics. The Tritium X design uses a 3-dot configuration that transitions from bright white dots in daylight to glowing reference points after dark, so you're never fumbling to find your sights.
TruGlo finished these sights with a nitride fortress treatment to resist corrosion, wear, and the kind of abuse that comes with regular carry or training. The snag-free profile fits standard Glock holsters without snag risk, and the solid steel construction means these sights will outlast most handguns. If your Glock 42 or 43 is a daily carry gun or a reliable training partner, upgrading to tritium night sights is one of the smartest upgrades you can make.

Frequently Asked Questions
Will these night sights work with my Glock 42 or 43?
Yes, these TruGlo Tritium X sights are specifically machined for the Glock 42 and Glock 43 platform and fit standard dovetail cuts on those models.
Do tritium sights need batteries or charging?
No. Tritium sights are self-powered by the radioactive tritium gas sealed inside the vials. They glow continuously without batteries, charging, or light exposure—they'll work the moment you need them.
Will these sights snag my holster?
The Tritium X design features a snag-free profile that is compatible with standard Glock holsters, so you won't have to worry about snagging during draw or reholster.
What's the difference between the white dots and the green tritium?
In daylight, you sight using the white front dot outline and the white rear dots. As light fades, the tritium lamps take over and provide a green glow for low-light and nighttime shooting without any manual transition.
