Zaffiri Precision exists to help a Glock stand out. Its ZPS optic-ready complete slides — in finishes from Armor Black to OD Green to Duck Camo — and its match and threaded barrels, including the oil-slick Spectrum PVD and gold PVD options, turn a plain factory pistol into something that looks and shoots custom. Everything is machined in-house in Florida, and since 2025 the brand has been part of the Night Fision family. Here is who they are, what they make, and what is worth buying.
Who Zaffiri Precision is
Zaffiri Precision exists to help a Glock stand out, machining ZPS optic-ready complete slides in finishes from Armor Black to Duck Camo, plus match and threaded barrels including oil-slick Spectrum PVD. Everything is made in-house in Florida.
Zaffiri Precision was founded in 2017 in Largo, Florida, with a simple mission the company still states plainly: make “products we want to use,” and help gun owners “stand apart from the crowd.” It set out to do that with aftermarket slides and barrels for Glock and SIG pistols, all made in-house at its Florida facility. In January 2025, Night Fision — the well-known tritium night-sight maker — acquired Zaffiri Precision, pairing Zaffiri’s slide-and-barrel work with Night Fision’s sights and optic plates to offer a more complete custom-pistol path.
On the quality ladder, Zaffiri sits in the mid-to-premium tier. The slides are precision-machined from single-billet 17-4 stainless steel for durability and tight tolerances, which is a genuine step above cast or lower-grade parts, and the catalog leans hard into distinctive finishes that most factory and even aftermarket parts don’t offer. The pitch is straightforward: real quality machining plus the looks to make your pistol unmistakably yours.
What Zaffiri Precision makes
ZPS complete slides
The ZPS line — ZPS.1 through ZPS.4 — is the flagship. These are complete, optic-ready slides for the most popular Glock models (17, 19, 34, 43/43X and more), machined from single-billet 17-4 stainless with aggressive serrations and factory optic cuts (Trijicon RMR and other footprints). “Complete” is the key word: many ship assembled and ready to drop onto a frame. What sets them apart is the finish selection — Armor Black, OD Green, Duck Camo, and more — so you can build a slide that looks like nothing else at the range.
Barrels
Zaffiri’s barrels for Glock and SIG come in threaded and non-threaded versions, match-grade, machined from 416R stainless. The finishes are again a highlight: black nitride and polished stainless for the classics, plus the eye-catching Spectrum PVD (an oil-slick, multi-color finish) and gold PVD for builds that want to show off. There are also side-ported barrels that vent gas to help flatten muzzle rise without a separate compensator.
Slide parts and completion kits
To support from-scratch builds, Zaffiri makes upper slide parts kits and completion hardware for Glock, so you can finish a bare slide into a working one. Paired with a Zaffiri slide and barrel, these let you assemble a complete custom upper.
Guide rods and small parts
Rounding out the line: stainless and polymer guide rod assemblies for various Glock generations and the slimline 43/43X/48, plus other small upgrade parts. They are the finishing pieces that complete a built or upgraded pistol.
Build quality and where it’s made
Zaffiri Precision makes its products in-house at its facility in Largo, Florida. The slides are precision-machined from single-billet 17-4 stainless steel — a strong, corrosion-resistant alloy — for durability and tight tolerances, and the barrels use match-grade 416R stainless. The distinctive finishes (Spectrum PVD, gold PVD, OD Green, Duck Camo) are not just paint; they are durable coatings applied to quality base parts. This is solid, made-in-USA precision manufacturing with a strong emphasis on aesthetics, now backed by the resources of its parent, Night Fision. You are paying for billet quality and a genuinely custom look, not for a hand-fitted-gunsmith price.
How Zaffiri Precision compares
In the Glock slide-and-barrel market, Zaffiri’s natural rival is Rival Arms and the broader field of aftermarket houses, sitting between value drop-ins and full custom shops. Its edge is the combination of single-billet 17-4 slides and a finish catalog that few competitors match — if you want OD Green, Duck Camo, or an oil-slick Spectrum barrel, Zaffiri is one of the first names that comes up. Against pure barrel makers, Zaffiri offers complete optic-ready slides too; against full custom builders, it offers drop-in convenience at a more accessible price. And since the 2025 Night Fision acquisition, the combined family can supply the slide, barrel, optic plate, and sights together — a one-stop custom-pistol path that standalone slide makers can’t quite match.
Who should buy what
- Custom-look builders: a ZPS complete slide in OD Green or Duck Camo.
- Red-dot shooters: an optic-ready ZPS slide cut for your footprint.
- Accuracy and style seekers: a match barrel in Spectrum or gold PVD.
- Suppressor users: a threaded Zaffiri barrel.
- From-scratch builders: a ZPS slide, barrel, and upper completion kit.
If you want the cheapest possible parts or a fully hand-fitted custom build, look elsewhere — but for billet-quality Glock slides and barrels with standout finishes, Zaffiri is one of the best.
The Zaffiri Precision philosophy
Zaffiri’s mission — “products we want to use” and helping owners “stand apart from the crowd” — explains the whole catalog. Plenty of companies make a competent black Glock slide; Zaffiri’s bet was that a lot of shooters want their pistol to look like theirs, not like every other one in the case. So it pairs the serious foundation (single-billet 17-4 stainless, match barrels, proper optic cuts) with finishes nobody else bothers to offer at scale. The result is gear that performs like a quality upgrade and looks like a custom build, without requiring a custom-shop budget. The Night Fision acquisition fits that same logic: combine the slide-and-barrel personality with sights and optic plates so a shooter can build a complete, distinctive pistol from one family of parts.
How to choose your Zaffiri Precision setup
Start with the slide, because it defines the look and is where Zaffiri shines. Pick a ZPS complete slide for your Glock model and choose an optic footprint that matches the red dot you want to run, then pick your finish — Armor Black for subtle, OD Green or Duck Camo to stand out. Add a Zaffiri barrel next: a match barrel in Spectrum or gold PVD if you want it to show, a threaded barrel if you run a suppressor or comp, or a side-ported barrel to help with muzzle rise. If you are building from a bare slide, add the upper completion kit, and finish with a guide rod. Because the brand is now part of the Night Fision family, you can top it off with matching sights and an optic plate. Match the parts to your Glock and your taste, and the build comes together as a coherent, custom-looking pistol.
The brand built to stand out — now part of a bigger family
Zaffiri Precision’s story is a tidy arc for a company barely old enough to be established. Founded in 2017 by people who wanted to build the parts they themselves wanted to run, it carved out a niche by treating finish and personality as seriously as machining — single-billet 17-4 slides that happen to come in Duck Camo, match barrels that happen to look like an oil slick. That combination of substance and style built a real following among Glock owners who wanted something different. Then, in January 2025, Night Fision acquired the company, folding Zaffiri’s slides and barrels into a lineup that already included some of the brightest night sights on the market. For shooters, the upshot is simple: the brand that helped you stand apart from the crowd is now part of a family that can outfit nearly the whole pistol, from the muzzle to the rear sight.
