The Trijicon Suppressor Night Sights for Glock 42/43/43x/48 deliver reliable, all-condition target acquisition — purpose-built to clear suppressor height while doubling as backup iron sights alongside the Trijicon RMR.
- Elevated suppressor height clears added bulk of a suppressed firearm
- Green tritium front lamp glows automatically in complete darkness
- Compatible with Glock 42, 43, 43X, and 48 pistols out of the box
- Sapphire jewel distributes tritium light evenly for a crisp sight picture
- Protective aluminum sleeves with silicone rubber cushioning absorb recoil
- Tritium lamps backed by Trijicon's industry-leading 12-year warranty
Who This Is For
These sights are ideal for concealed carriers, home defenders, and suppressor host owners who demand a proven low-light aiming solution on their compact or subcompact Glock. They're equally suited for shooters running an RMR red dot who want rugged, co-witness-capable backup iron sights they can trust when electronics fail.

Frequently Asked Questions
Will these sights work on a standard, unsuppressed Glock 42 or 43?
Yes. While these sights are specifically designed to clear the additional height of a suppressor or an optic like the Trijicon RMR, they function perfectly well on a standard, unsuppressed pistol. The taller sight radius can actually improve sight alignment for many shooters. You won't lose any functionality by running them without a suppressor or red dot.
Do these sights require batteries or any charging to glow in the dark?
No batteries or light charging are needed. Trijicon's tritium phosphor lamps are self-luminous — they glow continuously using the natural energy released by tritium gas. This means your sights will provide a reliable aiming point in total darkness without any preparation. Trijicon warrants the green lamps for 12 years from the date of manufacture, ensuring long-term performance.
Can I install these Trijicon night sights myself, or do I need a gunsmith?
Many experienced Glock owners install aftermarket sights at home using a quality sight pusher tool — Glocks do not require a press fit as tight as some other platforms. That said, if you're not comfortable with the process or don't have the right tools, having a qualified gunsmith install them is always recommended. Improper installation can damage the sights or the slide, and will void the warranty.
