P80 Full Size Slide Assembly – PF940v2/PFS9 – Black

Engineered for builders who demand precision from the ground up, the P80 Full Size Slide Assembly – PF940v2/PFS9 – Black is a factory-machined component designed to integrate directly with Polymer80 PF940v2 and PFS9 frame platforms. This slide assembly delivers a drop-in fit for full-size pistol builds, offering a reliable foundation for both new constructions and frame replacements. Constructed from billet steel with a black nitride finish, it provides corrosion resistance and dimensional stability across temperature extremes and high-round-count applications. Each unit undergoes a multi-point inspection to ensure consistent slide-to-frame lockup, extractor timing, and breech face squareness.

Overview

The P80 Full Size Slide Assembly – PF940v2/PFS9 – Black is a complete upper component set manufactured by Polymer80 to OEM-level tolerances. It includes the slide body, pre-installed extractor, loaded chamber indicator, and rear cover plate. The slide is profiled with functional serrations at the rear and front for positive manipulation under stress or gloved conditions. The black nitride surface treatment penetrates the steel substrate rather than coating the exterior, resulting in a wear-resistant finish that will not flake or peel. Assembly weight and recoil characteristics are balanced to match the PF940v2 and PFS9 frame geometries, preserving factory-style cycling dynamics.

Features & Specs

This slide assembly is built around the P80 Full Size Slide Assembly – PF940v2/PFS9 – Black specification, with each dimension verified against Polymer80 engineering blueprints. The following details define its construction and performance baseline:

• Material: 416R stainless steel, heat-treated to 40-42 HRC, finished with black nitride (salt bath nitrocarburizing) per MIL-DTL-13924
• Compatibility: Direct fit on Polymer80 PF940v2 and PFS9 full-size frames; does not require modification to frame rails or locking block
• OEM-style serrations: 20-line rear serrations and 8-line front serrations cut at a 90-degree angle for grip without sharp edges
• Pre-installed extractor: Sand-cast MIM extractor with spring and bearing; headspace and extractor tension verified at factory
• Loaded chamber indicator: Integrated LCI with spring-loaded plunger, compliant with state-level safety requirements where applicable
• Weight: 11.2 ounces (complete assembly as shipped) – maintains slide mass necessary for reliable cycling with standard-pressure 9mm loads
• Channel liner: Pre-installed polymer liner with anti-friction coating to reduce striker friction and debris intrusion

Who It’s For

This slide assembly is intended for builders who are constructing a full-size 9mm pistol using a Polymer80 PF940v2 or PFS9 frame. It suits users who prefer a factory-assembled slide over piecemeal part sourcing, particularly those who require consistent headspace and extractor timing from the first round. It is appropriate for range-use firearms, competitive shooting platforms, and defensive pistol builds where reliability and dimensional accuracy are primary concerns. The P80 Full Size Slide Assembly – PF940v2/PFS9 – Black is also a direct replacement for builders who have an existing frame and wish to upgrade from a subcompact or compact slide to a full-size configuration without re-engineering the frame rails. This product is not compatible with factory Glock frames, serialized P80 frames requiring significant modification, or non-Polymer80 aftermarket frames.

Shipping & FFL

This P80 Full Size Slide Assembly – PF940v2/PFS9 – Black is classified as a firearm part and is not a complete firearm, frame, or receiver. It ships directly to residential and commercial addresses within the United States without requiring transfer through a Federal Firearms License (FFL) dealer. Standard shipping carriers (UPS or FedEx) are used with signature confirmation upon delivery. International shipping is not available. Buyers are responsible for verifying that all components and assembled firearms comply with local, state, and federal laws. Polymer80 slide assemblies are not regulated as firearms under the Gun Control Act of 1968; however, federal law prohibits the assembly of a firearm by individuals prohibited from possessing firearms. By purchasing this product, you certify that you are legally eligible to own and assemble firearm components.
