Description
Running a red dot on your optics-ready Sig P-Series and want backup irons that stay out of the way until you need them? The Night Fision Optics Ready Stealth Night Sight Set was built for exactly that. These sights sit at a lower 1/3 co-witness with most leading pistol optics, so they clear the top of your red dot's battery box without stealing space in your window. The orange front ring pops in daylight, the rear stays blacked out to keep your focus on the dot, and Swiss tritium keeps all three dots glowing after dark.
What Sets the Stealth Sight Set Apart
Instead of the usual aluminum sleeve with a painted-on white ring, Night Fision uses a patented injection-molded ballistic polymer ring they call the Perfect Dot. It's built to resist chipping, cracking, fading, and peeling, and it packs roughly 30% more tritium than a lot of competing sights. Each vial sits under a domed lens that focuses the glow straight back at your eye for a crisp, defined dot in low light.
Built for the Optics-Ready Sig P-Series
The bodies are CNC-machined from high-quality steel and finished in black Nitride to fight wear and corrosion, so they hold up to recoil and daily carry. The Stealth Series runs a smaller 2.4mm front ring paired with a wider rear notch, which lets more daylight in around the front sight for faster target acquisition. Both sights carry machined serrations to cut glare from the sun or a handheld light. This orange-front, blacked-rear .345-.332 set fits standard Sig dovetails and pairs well with optics like the Trijicon RMR, Holosun 507c, 508t, and Romeo Pro.
Heads up on install: these are a press-fit sight and Night Fision recommends a gunsmith or a proper sight pusher to seat them correctly. Do that right and you've got a rugged, glow-in-the-dark backup that stays quiet behind your optic until the moment you need it.

Frequently Asked Questions
What pistols does this Night Fision Stealth sight set fit?
This set is cut for standard Sig Sauer dovetails and works across the optics-ready P-Series, including the P320, P365, and classic-line P225, P226, P228, and P229. The .345-.332 blade height is dialed in for a lower 1/3 co-witness with optics like the RMR, Holosun 507c and 508t, and the Romeo Pro. If you're running an aftermarket slide, double-check your dovetail dimensions before ordering.
Will the front and rear both glow in the dark?
Yes. All three dots use Swiss tritium, so the orange front and blacked-out rear both give you a green glow in low light with no charging or batteries needed. The domed lens over each vial focuses that glow back toward your eye for a sharper dot. Night Fision packs more tritium than a lot of competitors, so these read bright even in full dark.
Why choose these Stealth sights over standard-height irons for a red dot pistol?
The Stealth Series is purpose-built to sit behind an optic rather than replace it. They ride at a lower 1/3 co-witness so they barely clear the top of your red dot's battery box, keeping your optic window clear until you need the backup. The wider rear notch and smaller front ring also let more daylight in around the front sight for quicker acquisition.
Can I install these Night Fision sights myself?
These are a press-fit sight, and Night Fision recommends having a gunsmith install them or using a proper sight pusher. Steel sights in a steel or polymer slide need firm, even pressure to seat correctly without marring anything. If you have the right tool and some experience, it's doable at home, but a punch and hammer is a good way to damage a good set.
