P80 Full Size Slide Assembly – PF940v2/PFS9 – Black - polymer 80
About this product
The P80 Full Size Slide Assembly – PF940v2/PFS9 – Black is a complete polymer slide kit for 80% lower builds.
It combines a forged slide, barrel, recoil spring, and takedown pins in a ready‑to‑install package. Designed for competitive shooters, the kit reduces build time to under 30 minutes and meets federal 80% regulations.
What is the P80 Full Size Slide Assembly used for?
It is used to complete a handgun build by providing the slide, barrel, and internal components.
The assembly fits standard 9mm and .40 S&W receivers, allowing a fully functional pistol after the lower is finished. Users can test fire immediately after a simple 5‑minute fit check.
How does the P80 Full Size Slide Assembly compare to the Polymer80 PF940V2?
The ArcForge version weighs 1.23 lb, 0.2 lb lighter than the Polymer80 PF940V2 slide which is 1.43 lb.
Both use the same PF940v2 frame, but ArcForge’s tighter tolerances reduce slide‑to‑frame play by 0.03 mm, improving accuracy.
What does it weigh and what are the dimensions?
The slide assembly weighs 1.23 lb (558 g) and measures 7.5 in (190 mm) long, 1.2 in (30 mm) high, and 1.0 in (25 mm) wide.
These dimensions match standard full‑size pistols, ensuring compatibility with most aftermarket grips and sights.
Who is this NOT for?
This kit is not for beginners who have never worked with polymer receivers.
Builders lacking a basic 80% lower, a drill press, or a torque wrench will struggle, as the slide requires precise alignment and a correctly finished lower.
What's in the box?
The package includes a forged slide, stainless steel barrel (4.02 in), recoil spring assembly, takedown pins, slide stop, and a precision‑fit machined template.
All parts are pre‑finished in matte black and ready for immediate installation.
Is the P80 Full Size Slide Assembly worth it at $415?
Yes, at $415 it offers performance comparable to full‑metal slides for under half the price.
Compared to a $780 complete metal slide from a major brand, you save $365 while gaining a lighter, corrosion‑free assembly that holds zero‑point five‑hour accuracy in drift tests.

- Does it fit a .40 S&W lower?
- It does. The slide’s breech face is machined for both 9mm and .40 S&W dimensions, and the recoil spring can handle .40 pressures up to 12,000 psi.
- How long does shipping take?
- Standard US ground shipping averages 3‑5 business days. Expedited options deliver in 1‑2 days for an additional $25.
- Can I return it if it doesn't fit?
- Yes, returns are accepted within 30 days if the slide shows no signs of wear and is returned in original packaging. A restocking fee of 10 % applies.
- Does this work with a standard Glock 43 grip module?
- The slide’s width (1.0 in) matches Glock 43 grip frames, but the takedown pin spacing differs, requiring a compatible grip module or minor pin relocation.
