Glock 42/43 – Tritium Night Sights – Green 3-Dot – Brite-Site
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The TRUGLO Brite-Site Tritium sight set is a steel night 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 you a clean daylight picture and a steady glow when the light goes bad.
It is built to fit the Glock 42 and Glock 43 footprint family, with current TRUGLO fitment references also showing compatibility with the 43X and 48 slimline pattern. It keeps a snag-resistant profile that still works with standard holsters, which is what sights are supposed to do instead of acting like tiny steel boat anchors.
Fitment
- Fits Glock 42
- Fits Glock 43
- Current TRUGLO fitment reference also lists Glock 43X and Glock 48 slimline pattern compatibility
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 you 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.

Tools needed
Professional sight installation tools are strongly recommended. A proper sight pusher and correct front sight tool matter here unless you enjoy marking up slides and inventing new curse words.
Install notes
Pistol sights should be installed carefully with the right equipment. Improper installation can damage the slide or sights and can also create point-of-impact issues if the set is not installed correctly.
Verify before you buy
Verify your exact slimline Glock model before ordering. Glock slimline fitment is a lot cleaner than double-stack Glock fitment, but buying the wrong sight set still manages to happen every day somehow.
