Night Fision Sights G43/43X W/507K Yellownight Fision Co Witness Trit
The Night Fision Sights G43/43X W/507K are suppressor height tritium night sights purpose-built for Glock 43 and 43X pistols equipped with the Holosun 507K red dot optic. These sights solve the co-witness problem that plagues compact carry guns: they sit tall enough to allow a clean sight picture over your mounted optic while maintaining the low-profile handling that makes the 43/43X so concealable. Whether you're setting up a duty gun, a serious carry rig, or a specialized close-quarters build, these sights deliver the sight picture you actually need.
Night Fision's tritium technology means your sights stay visible in dim light and darkness—no batteries required, no gimmicks. The yellow front sight provides high contrast in most lighting conditions while the black rear sight minimizes glare and keeps your focus on the target. The suppressor-height profile isn't just about optics compatibility; it keeps your gun running reliably with suppressors or without, giving you real flexibility in how you configure your 43/43X.
If you're running a Holosun 507K and want sights you can actually use when your optic fails or you need a backup sight picture, this is the no-compromise setup. These aren't generic sights shoehorned onto a platform—they're engineered specifically for how you'll actually shoot a 43/43X with an optic mounted on top.

Frequently Asked Questions
Will these sights work with my Glock 43X and Holosun 507K?
Yes. The Night Fision Sights G43/43X W/507K are specifically designed to co-witness with the Holosun 507K red dot. The suppressor height profile allows you to shoot through the optic and use the sights as a backup when your optic is off or fails.
Do I need suppressor height sights even if I don't run a suppressor?
Not necessarily for the suppressor itself, but if you're mounting an optic like the 507K on your 43/43X, you need suppressor-height sights to get a usable sight picture. Standard-height sights will sit too low. If you're running iron sights only with no optic, standard sights would be fine.
How do tritium night sights work?
Tritium is a radioactive isotope that produces a faint glow in the dark without any battery or external activation. Your Night Fision sights will be visible in low light, darkness, and at night without any maintenance or power source needed.
Can I use these sights on other Glock models?
These sights are engineered specifically for the Glock 43 and 43X. Compatibility with other Glock models is not covered by the information provided.
