Glock 42/43/43X/48 – Tritium Night Sights – Green 3-Dot
PLEASE DOUBLE CHECK DETAILS, MODEL FITMENT, MOS COMPATIBILITY, AND INSTALLATION REQUIREMENTS BEFORE PURCHASE.
The TRUGLO Tritium night sight set is a steel sight upgrade built for slimline Glock pistols that need real low-light visibility without batteries, charging, or goofy gimmicks. This set uses a traditional green tritium 3-dot layout with a black steel body, giving the shooter a clean daylight sight picture and a steady glow when the light gets ugly.
This sight set is built for the Glock 42, 43, 43X, and 48 slimline pattern. It uses a snag-resistant profile that fits standard holsters, which is exactly what sights are supposed to do instead of acting like tiny steel boat anchors.
Fitment
- Fits Glock 42.
- Fits Glock 43.

Does NOT Fit
- Does not fit MOS models unless your specific sight-height and optic setup is verified separately.
- Does not fit standard double-stack Glock models such as G17, G19, G19X, G26, G34, G45, or G47.

What It Does
This sight set replaces the factory sights with a steel tritium 3-dot system that stays visible in daylight and glows green in darkness. That gives the shooter a more useful sight picture for defensive carry, range work, and low-light shooting without relying on electronics.
Why It’s Worth It
Factory plastic sights are fine if your standards are low and your expectations are lower. These give you steel construction, tritium illumination, and a holster-friendly shape in one clean upgrade that actually matters.
