Night Fision Sights Sig P320 W/Rmr Orangenight Fision Co Witness Trit

Night Fision suppressor height sights for the Sig P320 with RMR cut combine cutting-edge tritium technology with a clean, modular design that works seamlessly alongside your red dot optic. Built from CNC-machined steel with a durable Black Nitride finish, these witness-style sights deliver the brightness and reliability you need whether you're running low-light drills at the range, training for duty, or carrying for self-defense. The suppressor height profile clears your mounted RMR while keeping your irons ready as a backup or failsafe—exactly what serious shooters expect from premium co-witness sights.

What sets Night Fision apart is their injection-molded sleeve design, which abandons the old aluminum-and-paint approach in favor of a bezel that holds tritium vials securely while amplifying their light output into what they call The Perfect Dot. A domed lens collimates the tritium rays, sharpening your sight picture in low light and extending visibility in darkness—a meaningful advantage when seconds matter. The orange-accented front sight offers quick target acquisition in daylight, while the tritium core keeps working when your flashlight's not an option. Swiss tritium and stateside manufacturing ensure you're getting genuine, long-lasting performance in a component that won't let you down.

These sights are built for shooters who demand rugged reliability and aren't willing to compromise on night-shooting capability. Professional installation by a gunsmith is recommended to ensure proper fitment and zero on your P320. If you're upgrading a duty gun, a competition rig, or a home-defense platform, Night Fision sights deliver the kind of dependable luminosity and durability that makes a real difference when visibility is low.

Frequently Asked Questions

Will these sights work with my RMR or other red dot mounted on a P320?

Yes. The suppressor height profile is specifically designed to co-witness with an RMR-mounted optic on the Sig P320. Your sights will remain visible and usable alongside your red dot, giving you a reliable backup or allowing you to run irons-only if your optic fails or needs service.

How bright are Night Fision tritium sights compared to standard night sights?

Night Fision's injection-molded sleeve design and domed lens collimates the tritium rays into what they call The Perfect Dot, which produces a brighter and sharper sight picture than conventional aluminum-sleeve designs. The result is better low-light visibility and longer-range usability in darkness.

Do I need a gunsmith to install these sights?

Professional gunsmith installation is recommended. Proper sight installation and zero are critical for accuracy and safety, especially on a duty or defensive firearm.

How long does the tritium last in these sights?

These sights use Swiss tritium, which is known for reliable, long-lasting performance. Tritium has a half-life of approximately 12 years, meaning the sights will remain usable well beyond that period, though brightness gradually diminishes over time.
