Night Fision Sights G17/19/45 W/Rmr Orangenight Fision Co Witness Trit

Night Fision sights for Glock 17, 19, and 45 with RMR-cut compatibility bring tritium-powered visibility to your carry or duty gun. These witness-style sights pair a rear aperture with a front post design, giving you fast target acquisition in low light and the flexibility to mount a red dot on the slide simultaneously. The orange front sight element stands out in daylight while the tritium inserts activate automatically when ambient light drops—ideal for home defense, concealed carry, or low-light shooting scenarios where you need reliable sights you can trust without batteries.

Night Fision has built a solid reputation for tritium sight quality, and these sights deliver that dependability in a user-friendly package. The witness-style rear aperture is forgiving and quick to use, especially if you're transitioning between iron sights and optics or learning to shoot in variable light. The orange front sight element enhances visibility during the day, while the tritium cores ensure you've got a sight picture when it matters most.

Installation is straightforward on any Glock 17, 19, or 45, and the RMR-cut design lets you mount a red dot reflex sight on the rear of the slide if you choose to upgrade your sighting system down the road. Whether you're running irons only or planning a hybrid setup, these sights adapt to your shooting style and mission.

Frequently Asked Questions

Will these Night Fision sights work with my Glock 17, 19, and 45?

Yes, these sights are engineered to fit Glock 17, 19, and 45 pistols. Verify your specific model before purchase if you have questions about fitment.

Can I mount a red dot sight on top of these sights?

Yes. The RMR-cut design on the rear of the slide accommodates standard RMR and RMR-footprint red dot sights, so you can run a hybrid iron and optic setup if you choose.

Do the tritium inserts require a battery?

No. Tritium is a self-luminous radioactive isotope that glows continuously without requiring charging or batteries. It will remain visible in complete darkness for the lifespan of the sight.

What is the orange element on the front sight?

The orange front sight post is a high-visibility element designed to help you acquire your target quickly in daylight conditions. The tritium core inside ensures you can still see the sight in low light and darkness.
