Polymer80 PF940C™ 80% Pistol Frame Only

The Polymer80 PF940C™ 80% Pistol Frame Only represents a foundational component for the serious builder seeking a fully customizable, compact handgun platform. As a complete polymer frame pre-machined to 80% completion, this frame requires final finishing and assembly of your own parts kit, allowing you to construct a firearm that meets your exact specifications without serialization requirements from a manufacturer. This frame is designed for compact Glock Gen3-compatible slide assemblies, offering a streamlined build process with professional-grade results.

Overview

Built from high-impact, reinforced polymer, the Polymer80 PF940C™ 80% Pistol Frame Only is engineered for durability under repeated use. The frame features an integrated locking block system and a steel-reinforced rail system, ensuring a precise fit with aftermarket slides and barrels. Unlike complete frames, this 80% variant requires you to complete the remaining work: drilling the trigger pin holes, milling the front and rear rail pockets, and finishing the frame to your preference. The result is a firearm that is uniquely yours, with no serial number markings until you choose to serialize it. This frame is a direct match for compact-sized builds, typically compatible with 9mm and .40 S&W calibers.

Features & Specs

• Material and Construction: The frame is injection-molded from a proprietary polymer blend that resists impact, UV degradation, and solvents. It includes a steel front rail and a polymer rear rail insert, both precision-machined to accept standard locking blocks and trigger mechanisms.
• Compatibility and Fit: Designed for Gen3 Glock 19 and 23 pattern slides, barrels, and parts kits. The frame also accepts a range of aftermarket triggers, extended controls, and accessories. The PF940C is a compact frame, ideal for concealed carry or duty use.
• Build Process: The 80% frame is pre-machined with the main grip contour, trigger guard, and slide rails partially completed. You will need to complete the following steps: drill three locating pin holes (trigger, slide lock, and rear rails), cut the front rail slots, and finish the internal surfaces. This process requires basic tools such as a drill press, vise, and standard hand tools.
• Specifications: Category: Frames. Manufacturer: Polymer80. Weight: approximately 4.5 ounces (unfinished). Overall length: 7.3 inches. Compatible with most Gen3 compact parts kits.

Who It’s For

This product is intended for experienced firearms enthusiasts, custom builders, and individuals looking to create a personalized firearm without the restrictions of a serialized receiver.

The Polymer80 PF940C 80% Pistol Frame Only is not for beginners. It is for those who want to invest time and skill into a project that yields a reliable, custom handgun. It is ideal for shooters who prefer a compact frame for everyday carry, competition, or as a backup weapon, and who want full control over part selection, trigger feel, and ergonomics.
