Night Fision makes some of the brightest tritium night sights you can put on a handgun. The patented Perfect Dot tritium sights, the Optics-Ready Stealth sets built to co-witness with a red dot, and the company’s signature domed lenses packed with extra tritium have earned it a serious reputation among carry and duty shooters. As of 2025 the company also owns slide-and-barrel maker Zaffiri Precision. Here is who they are, what they make, and what is worth buying.

Who Night Fision is

Night Fision makes some of the brightest tritium night sights you can put on a handgun, built on its patented Perfect Dot sights and domed lenses packed with extra tritium, plus Optics-Ready Stealth sets that co-witness with a red dot.

Night Fision is based in Dearborn, Michigan, and is a recognized leader in tritium night sights, iron-sight systems, and optic-plate adaptors. The company, led by owner CJ Karchon, built its name on one promise: a brighter, sharper night sight than the competition. In January 2025 Night Fision acquired Zaffiri Precision, the Largo, Florida maker of distinctive CNC-machined slides and barrels — a move that pairs Night Fision’s iron-sight expertise with Zaffiri’s slide-and-barrel work and gives the company a much deeper aftermarket lineup.

On the quality ladder, Night Fision sits in the premium night-sight tier. These are not bargain sights; they are CNC-machined steel, Swiss-tritium, made-in-USA sights built to out-glow the established names. If your priority is the brightest, most visible sight picture you can get for a defensive handgun, Night Fision is squarely in the conversation.

What Night Fision makes

Perfect Dot tritium night sights

The Perfect Dot is the flagship. Night Fision’s patented, injection-molded sleeve creates a brighter and more durable ring around the tritium vial, and the company fills a slightly larger glass lamp with more tritium gas — about 30% more than a typical night sight — then caps it with a domed lens that focuses the glow into a sharp, intense dot. Front rings come in high-visibility yellow, orange, or white, and the rear is offered in U-notch or square-notch. The result is a sight that is easy to pick up in daylight and bright at night.

Optics-Ready Stealth Series

As red dots took over the handgun world, Night Fision built the Optics-Ready Stealth sets specifically to work with them — suppressor-height sights that co-witness through popular optics like the Trijicon RMR/RMRcc, Holosun 507c/507k/EPS, and SIG ROMEO, so you keep a usable iron backup even with a dot mounted. There are dedicated sets for the most common Glock and SIG carry guns and their optic cuts.

Suppressor-height and standard sights

Beyond the optics-ready line, Night Fision makes standard-height night sights for everyday carry and duty, plus taller suppressor-height sights for guns running a can or a tall optic. The Accur8 line offers a simplified front-dot sight picture for newer shooters.

Fiber optic sights and optic plates

Night Fision also makes fiber-optic sights for daylight target work, and a range of optic mounting plates and adaptors that let you bolt a given red dot onto a given pistol’s optic cut — an increasingly important part of the carry-gun puzzle.

Zaffiri Precision slides and barrels

Since the 2025 acquisition, the Night Fision family also includes Zaffiri Precision — uniquely styled CNC-machined slides and threaded/match barrels, primarily for Glock-pattern pistols. For shooters building out a complete custom pistol, the combined company can now supply the slide, the barrel, the optic plate, and the sights from one source.

Build quality and where it’s made

Night Fision sights are built in the USA, CNC-machined from high-quality steel, and finished in black nitride for wear and corrosion resistance. The tritium is Swiss-sourced, and the company’s whole pitch rests on using more of it — a larger lamp, more gas, and that focusing domed lens — to produce a brighter, longer-lasting glow than flat-lens competitors. It is precision small-part manufacturing where the details matter: a night sight lives or dies on how bright and how durable it is, and Night Fision engineers both. You are paying a premium for genuinely brighter, well-made sights, not for a logo.

How Night Fision compares

In the premium night-sight market, Night Fision goes head-to-head with Trijicon (the HD and Bright & Tough lines), XS Sights, Ameriglo, and Meprolight. Trijicon is the established default; Night Fision’s pitch against it is straightforward — more tritium and a domed lens for a brighter, sharper dot, often at a competitive price. Against XS’s big-dot front sights, Night Fision offers a more traditional ringed sight picture with class-leading brightness. And with the Optics-Ready Stealth line, Night Fision is among the best at the specific modern problem of co-witnessing irons through a red dot. The 2025 Zaffiri acquisition pushes the brand beyond sights into a broader custom-pistol ecosystem, which none of the pure-sight competitors offer.

Who should buy what

Everyday carry: a Perfect Dot set with a high-visibility orange or yellow front ring.
Red-dot pistol owners: the Optics-Ready Stealth set for your gun and optic cut.
Suppressor or tall-optic users: the suppressor-height sights.
Custom-pistol builders: Night Fision sights and optic plate plus a Zaffiri slide and barrel.
New shooters: the Accur8 simplified front-dot sight picture.

If you want the cheapest possible iron sights, Night Fision is not the budget pick — but for the brightest, sharpest defensive night sights, it is one of the best.

The Night Fision design philosophy

Night Fision is built around a single, almost obsessive idea: make the sight you can actually see, in any light. Everything about the Perfect Dot serves that — the larger tritium lamp for more glow, the injection-molded sleeve for a crisp daylight ring, and the domed lens that focuses the tritium rays instead of letting a flat lens scatter them. That is engineering aimed squarely at the moment a sight matters most: a low-light defensive encounter, when a dim or fuzzy dot can cost you. The Optics-Ready Stealth line is the same philosophy adapted to the red-dot era — making sure you can still see usable irons through the glass. And the Zaffiri acquisition extends the logic outward: if the company can build the brightest sights, why not also offer the slide, barrel, and optic plate to go with them? It is a focused, problem-first approach to the carry gun.

How to choose your Night Fision setup

Start with how your pistol is set up. If you run irons only, a Perfect Dot set is the upgrade — pick a front ring color (orange and yellow are the easiest to see fast) and a rear notch shape you like. If you run a red dot, go straight to the Optics-Ready Stealth set made for your specific pistol and optic footprint, so the irons co-witness correctly. Add a Night Fision optic plate if your slide needs an adaptor for your chosen dot. Shooters with a suppressor or a tall optic should size up to suppressor-height sights so the sight picture clears the obstruction. And if you are building a custom pistol from the ground up, the combined Night Fision and Zaffiri catalog now lets you source the slide, barrel, plate, and sights together. The throughline: match the sight to your light setup and your optic, and let Night Fision’s brightness do the rest.

The brightness obsession — and a 2025 expansion

Most night-sight makers treat tritium as a commodity: a standard vial, a flat lens, a glow that fades over the years. Night Fision treated it as an engineering problem to win. By using a bigger lamp, roughly 30% more tritium, a patented daylight ring, and a focusing domed lens, the company set out to simply be the brightest sight on the shelf — and that single-minded focus is why it broke into a market long dominated by one or two giants. The January 2025 acquisition of Zaffiri Precision was the next chapter: a sight specialist absorbing a respected slide-and-barrel maker to offer a complete custom-pistol path, from the muzzle to the rear sight. For a Dearborn company that started by chasing a brighter dot, growing into a full aftermarket pistol house is a notable arc — and it all traces back to the same question of how well you can see your sights when it counts.
