Zaffiri Precision ZPS.3 Complete Slide (9 mm) – Optic-Ready for Glock® 43/43X
Elevate your Glock 43 or 43X with the Zaffiri Precision ZPS.3 Complete Slide-a precision-crafted upgrade that delivers style, performance, and optics-ready functionality right out of the box. Built from billet stainless steel and engineered for shooters who value accuracy and reliability, it’s a standout slide for modern 9 mm builds.
Premium Construction & Design
- Billet 17‑4 Stainless Steel Core
Crafted from a single billet of 17‑4 stainless, the ZPS.3 slide offers exceptional rigidity, corrosion resistance, and tighter tolerances than standard cast or forged slides-resulting in improved lock-up and enhanced accuracy.
- Cerakote® Finish (Armor Black)
Its durable Armor Black Cerakote finish resists abrasion, protects against metals fouling, and maintains the slide’s refined aesthetic under heavy use.
Optics-Ready with Modern Sights
- RMS‑C / RMR‑Compatible Cut
The slide comes pre-cut for Shield RMSc, Holosun 407C/507C, or similar optics, placing your red dot sight in a perfect, low co-witness footprint for combat or competition use.
- Included Cover Plate and Mounting Hardware
A black-anodized cover plate and hardware are included to protect the optic cut when not in use or during transport.
Functional Features & Finish
- Threaded Barrel with TiN Accents
The slide includes a threaded barrel finished in Titanium Nitride (TiN), offering enhanced wear resistance and support for compensators or suppressors-a performance-friendly addition for advanced builds.
- Lightening Cuts & Aggressive Serrations
Strategically milled lightening cuts reduce slide weight for faster manipulation, while deep, grippy serrations on the front and rear offer intuitive slide racking, even under stress or with gloves
- HD Fiber-Optic Sights Included
Mounted sights add immediate usability out of the box, while allowing for future optic customization.
- Built-in Upper Parts Kit & Recoil Spring Assembly
Supplied with a Gen 3-compatible internal parts kit (polymer recoil spring assembly included), the ZPS.3 slide is designed for easy drop-in installation with existing Glock lower components.
Performance & Shooter Benefits
- Consistent Lock-Up and Accuracy
The billet construction and precision machining tighten lock-up, helping to reduce shot dispersion artificially seen with OEM slides.
- Optic Integration Without Gunsmithing
Pre-cut optics footprint, pre-fitted hardware, and sighting system make this slide a hassle-free upgrade.
- Weight-Balanced for Speed and Control
Lightening cuts shave mass without compromising integrity-enhancing slide speed, recoil control, and reset performance.
- Suppressor & Compensator Ready
The threaded barrel expands your build’s versatility and compatibility with aftermarket upgrades.
