Glock 39930 Green Night Sight Black Frame Fits Glock 42/43
The Glock 39930 Green Night Sight set is a tritium night sight solution purpose-built for the Glock 42 and Glock 43, two of the most popular compact carry pistols on the market. With a slim 6.1mm profile, these sights are engineered to fit the reduced frame dimensions of these single-stack 9mm and .380 ACP handguns without adding bulk to an already trim package. Whether you're zeroing in at the range or carrying for self-defense, a quality night sight setup transforms your low-light capability and gives you target acquisition confidence when it matters most.
Glock's tritium night sight technology uses contrasting inserts that glow independently in darkness, eliminating the need for external light sources during night shooting. The 3-dot configuration is a proven sight picture that shooters intuitively understand, making transitions between daylight and low-light engagement natural and repeatable. The rear sight component is included, giving you a complete two-piece set ready to install on your compact Glock.
These sights appeal to concealed carry shooters who refuse to compromise on night capability, range competitors running their carry gun, and anyone who puts regular rounds downrange with a G42 or G43. Installation requires basic gunsmithing or a visit to your local gunsmith, but the upgrade is a direct swap with no modifications to the slide.

Frequently Asked Questions
Will these sights fit my Glock 42 or 43?
Yes—these are designed specifically for Glock 42 and Glock 43 pistols. The slim 6.1mm profile matches the compact slide geometry of both models.
What's included in this set?
The set includes both the rear night sight and front sight, giving you a complete 3-dot tritium sight picture out of the box.
How do tritium night sights work?
Tritium is a self-illuminating radioactive isotope that glows in darkness without requiring batteries or external light. The contrasting inserts make the sights visible in daylight as well, so you get reliable target acquisition in all lighting conditions.
Do I need a gunsmith to install these?
Installation requires removing the factory sights and pressing the new ones onto the slide. Most shooters have a gunsmith perform this work to ensure proper fit and function, though some experienced gunsmiths have the right tools to do it in-house.
