P80 Full Size Slide Assembly – PF940v2/PFS9 – Black

If you are building a Polymer80 pistol from the ground up, the slide assembly is the mechanical heart of your project. This P80 full size slide assembly – PF940v2/PFS9 – black is the factory companion piece for the PF940v2 and PFS9 frames, designed to drop in with minimal fitting. It is machined from billet 416 stainless steel, then treated with a matte black nitride finish that holds up to holster wear and range time. Every component—from the extractor to the striker assembly—is pre-installed, so you are not hunting for tiny springs on your workbench. Whether this is your first build or your fifth, this slide assembly delivers the same reliability you expect from a duty-grade pistol.

Overview

This complete slide assembly is manufactured in the United States by Polymer80, the company that defined the DIY pistol market. It is built to spec for the PF940v2 and PFS9 full size frames. The black nitride finish is uniform, non-reflective, and corrosion resistant. The slide comes fully assembled with a stainless steel barrel, recoil spring assembly, and all internal components installed. You simply mount it onto your completed frame and perform a function check. For builders who prefer a factory-tested solution over piecing together parts, this P80 full size slide assembly – PF940v2/PFS9 – black is a straightforward upgrade that saves time without sacrificing quality.

Features & Specs

• Complete assembly: Slide, barrel, recoil spring, sights, and all internal components come pre-installed. No need to press in sights or stake the extractor.
• Black nitride finish: Salt bath nitride treatment extends surface hardness and provides a low-glare appearance that matches most frame colors.
• Precision barrel: Buttons-rifled 416 stainless barrel with a target crown. Feeds and extracts reliably with factory ammunition.

This slide assembly uses a standard 9mm chamber and fits both the PF940v2 and PFS9 lower receivers. The slide is cut for standard height sights (included) and is compatible with most aftermarket optics if you choose to have it milled later. The recoil assembly is a captured dual-spring design that reduces felt recoil and prolongs service life. All internal parts are sourced from US-based suppliers and meet or exceed OEM tolerances.

Who It’s For

This P80 full size slide assembly – PF940v2/PFS9 – black is ideal for anyone building a full size Polymer80 pistol from a stripped frame. It suits first-time builders who want plug-and-play reliability, as well as experienced gunsmiths who prefer to start with a complete top end and focus on trigger tuning or frame finishing. It also works as a direct replacement for a worn or damaged slide on an existing PF940v2 or PFS9 build. If you want to keep your build consistent with factory spec—same slide mass, same barrel length, same sight radius—this assembly is the logical choice. It is not meant for compact or subcompact frames; verify your frame model before ordering.
