Trijicon Green Night Sight Set for Glock 42 with Front & Rear Sights

The Trijicon Green Night Sight Set for Glock 42 brings low-light shooting capability to one of the market's most popular compact pistols. This matched front and rear sight pair uses tritium and phosphor-filled lamps to stay visible in both bright daylight and complete darkness—no batteries required. The green lamps give you a distinct aiming reference that many shooters prefer, and Trijicon backs them for 12 years from manufacture. Whether you're training at the range, carrying for personal defense, or running drills in variable light, these sights let you acquire your target quickly when sight picture matters.

What sets these Trijicon sights apart is their height. The raised profile clears a suppressor when mounted on your Glock 42, so if you run a can, these will still give you a functional aiming solution rather than forcing you to hunt for co-witness. The three-dot sight picture is the gold standard for speed and intuitive alignment. Each lamp sits inside a protective aluminum sleeve with silicone rubber cushioning to absorb recoil shock, and a sapphire jewel distributes the tritium glow evenly across the lens for consistent brightness across your field of view.

Installation is straightforward—this is a direct fit for the Glock 42. If you run an optic on your slide, these serve as a solid backup iron sight system. The green color offers a different visual signature than the more common yellow tritium, giving you options based on your preference and your shooting environment. For a compact carry gun that needs to work in low light, this is a serious upgrade from factory plastic sights.

Frequently Asked Questions

Will these sights work with a suppressor on my Glock 42?

Yes. The suppressor-height profile of this sight set is specifically designed to clear the added height of a suppressor mounted to your barrel, so you'll maintain a usable sight picture even when running a can.

Can I use these as backup sights if I mount an optic on my Glock 42?

Yes. These sights function as a complete backup iron sight system and can be used alongside a mounted red dot or similar optic.

How long do the tritium lamps stay bright?

Trijicon warrants the green lamps for 12 years from the date of manufacture. The lamps will gradually dim over time but remain functional beyond the warranty period.

Do these sights require batteries?

No. Tritium is self-luminous and requires no batteries, power, or external light source to function.
