Polymer80 PF940v2™ 80% Pistol Frame ONLY – 9mm

Product Overview

The Polymer80 PF940v2™ 80% Pistol Frame is the foundational component for builders seeking a custom, semi-automatic 9mm platform. Designed for the experienced firearms enthusiast and hobbyist gunsmith, this frame is a “80%” receiver, meaning it is not a firearm as sold and requires machining and the installation of additional parts to complete. It is engineered to serve as the core for building a personalized handgun compatible with a wide range of Generation 3 Glock® slides and parts, including models like the G17, G22, G34, and their long-slide variants. This project is ideal for those who value the process of customization, understanding firearm mechanics, and achieving a fit and finish tailored to their specific ergonomic preferences.

Key Features

• Superior Ergonomic Design: The frame incorporates an extended beavertail and an integrated thumb ledge, promoting a higher, more controlled grip and mitigating slide bite for improved handling and recoil management.
• Enhanced Trigger Guard: A double-undercut trigger guard allows for a significantly lower and firmer master-hand grip, while also providing ample space for a support-hand index finger, a critical feature for advanced shooting techniques.
• Versatile Compatibility: This single polymer frame is designed to host a variety of Gen 3 Glock®-compatible upper assemblies, supporting calibers including 9mm, .40 S&W, .357 SIG, and more, making it a highly adaptable base for multiple builds.
• Durable Polymer Construction: Manufactured from a high-strength, reinforced polymer, the frame offers a proven balance of lightweight durability and rigidity essential for reliable semi-automatic action.
• Jig-Ready 80% Design: The frame comes prepared for the builder to complete the final machining steps using common tools, providing a legitimate and engaging project for those interested in the build process itself.
• Aggressive Texturing: Strategically placed texturing on the grip and front strap ensures a secure, non-slip hold in various environmental conditions, contributing directly to shooter control and safety.

Performance & Applications

The primary application for the PF940v2 frame is as a custom build project. It is not a finished firearm, but the starting point for creating a personalized tool. Once completed with a parts kit and a slide assembly, its performance is derived from the quality of its components and the builder’s skill.

Custom Competition Firearm: Builders often use this frame as the foundation for a competition-ready handgun. The ergonomic features like the thumb ledge and undercut trigger guard are directly beneficial for speed shooting and managing recoil during rapid strings of fire, allowing for faster, more accurate follow-up shots when paired with a quality slide and trigger assembly.

Ergonomic Upgrade Platform: For shooters who find the grip angle or contours of standard frames suboptimal, the PF940v2 provides a modern, feature-rich alternative. It allows an individual to build a handgun that fits their hand perfectly from the ground up, potentially improving comfort and control during extended training sessions or recreational shooting.

Technical Education Project: For the mechanically inclined individual, completing an 80% frame offers a profound, hands-on understanding of the function and interaction of a pistol’s fire control group, slide, and frame. It demystifies the operation of a semi-automatic pistol and fosters a deeper appreciation for precision and gunsmithing practices.
