Night Fision Tritium Night Sight Set for Glock 42/43/43X - U-Notch Rear, Black Ring, Steel Nitride

The Night Fision Tritium Night Sight Set for Glock 42/43/43X brings reliable low-light performance to compact carry pistols with a design that works in daylight too. These self-illuminating tritium sights give you an "always on" glow without batteries, making them ideal for defensive shooters, concealed carry users, and anyone who wants fast sight acquisition when it matters most. Night Fision's Perfect Dot design uses 30% more tritium than conventional night sights, delivering unusually bright aiming dots that cut through darkness—and the daylight-fluorescing ring around the front sight keeps your sights visible in any lighting condition.

This set pairs a U-notch rear sight with a black-ring front sight in steel nitride finish. The front sight is intentionally brighter than the rear, which naturally encourages front-sight focus and keeps your eyes on the target when you need speed. The tritium vial is held more securely than older designs, protecting against the knocks and dings that come with daily carry. Rugged 4140 steel construction with matte black nitride coating resists wear and corrosion, so your sights stay functional and looking sharp through years of use.

Night Fision engineered these sights specifically for the Glock 42, 43, and 43X—they're not a universal compact conversion but a purpose-built set in factory height. If you're running a suppressor-equipped compact Glock, check compatibility before ordering. The U-notch rear with plain black surface and black-ring front dot gives you a clean, professional sight picture in both daylight and darkness. Whether you carry for work, personal defense, or off-duty readiness, these sights deliver the performance and reliability that come with a trusted name in tritium optics.

Frequently Asked Questions

Will these sights fit my Glock 42, 43, or 43X?

Yes. This set is engineered specifically for the Glock 42, 43, and 43X in factory height. If your pistol is equipped with a suppressor, check whether you need suppressor-height sights instead, as this set comes in standard factory height.

Do these night sights work in daylight?

Yes. The daylight-fluorescing ring around the front sight ensures the aiming dot remains visible and easy to locate in bright conditions. The tritium provides the low-light glow, so you get effective sight picture in daylight or darkness.

How long do tritium night sights stay bright?

Tritium is self-illuminating and requires no batteries or charging. The glow is always on, but like all tritium products, brightness slowly decreases over time as the tritium ages. Night Fision's increased tritium content (30% more than standard) provides brighter initial performance.
