Polymer80 P80 Compact Slide Assembly -PF940C/PFC9 – Cobalt

If you are building out a Polymer80 PF940C or PFC9 compact frame, the slide assembly is the next major decision. The P80 Compact Slide Assembly -PF940C/PFC9 – Cobalt is a factory-machined option designed to pair directly with those frames. It is built for builders who want a clean, reliable slide without chasing after custom gunsmith fitting. This is a drop-in assembly that keeps your build straightforward and functional.

Overview

The P80 Compact Slide Assembly -PF940C/PFC9 – Cobalt is a complete slide unit from Polymer80, intended for compact 9mm builds. It comes pre-assembled with the internals you need to finish your frame project. The cobalt finish gives it a subdued, matte appearance that resists glare and holds up under regular use. Because it is made specifically for the PF940C and PFC9 frames, you won’t have to modify the slide or the frame to get it running. It is a solid middle-ground option for anyone who wants a factory-built slide without the premium price of fully custom work.

Features & Specs

This slide is machined from 416 stainless steel and then treated with a cobalt nitride finish. The finish reduces friction and provides corrosion resistance. The assembly includes a match-grade 416 stainless barrel, a stainless guide rod, and a serrated rear sight dovetail. The slide is cut for standard compact sights, so you can swap them out if you prefer a specific height or profile.

• Complete drop-in slide assembly for PF940C and PFC9 frames
• 416 stainless steel slide with cobalt nitride finish
• Match-grade 416 stainless barrel included
• Serrated rear sight dovetail and front sight cut
• Stainless guide rod and spring assembly
• Pre-installed extractor, firing pin, and safety plunger

For builders who want to verify compatibility, the slide length matches the compact frame’s dust cover. The barrel is 4.02 inches, and the slide overall length is standard for compact Glock-pattern slides. The weight is balanced to reduce muzzle rise without making the front end feel heavy.

Who It’s For

This slide assembly is aimed at the DIY builder who wants a reliable, factory-spec slide without the hassle of sourcing individual parts. If you have a PF940C or PFC9 frame sitting in your workbench and you are ready to complete the build, this is a direct path to a functioning pistol. It is also a good choice for someone who wants a spare slide for training or range use, kept in a different finish than their primary slide. The P80 Compact Slide Assembly -PF940C/PFC9 – Cobalt works well for both first-time builders and experienced hands who appreciate a no-fuss assembly. Just mount it on your completed frame, confirm your sights, and function-check it.

Shipping & FFL

This slide assembly does not include a frame or receiver, so it ships directly to your door without an FFL transfer. No background check is required for the slide itself. However, if you are purchasing a complete firearm or a frame, that item must go to a licensed Federal Firearms License (FFL) dealer. You are responsible for knowing and following all local, state, and federal laws regarding firearm parts and assembly. We recommend checking with your local FFL if you have any questions about the legality of completing a frame in your area.
