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 handgun platform. Designed for the experienced firearms enthusiast and hobbyist builder, this frame is a blank canvas, engineered to accept a wide array of Gen 3 Glock®-compatible parts kits. Its primary use is as the core of a personalized build project, allowing for the creation of a tailored 9mm pistol that reflects individual preferences in ergonomics and performance. As an 80% frame, it requires machining and assembly to become a functional firearm, offering a deep understanding of the platform’s mechanics. This process is intended for individuals who enjoy the technical challenge and satisfaction of building their own equipment, within the full scope of applicable laws.

Key Features

• Versatile Compatibility: Engineered to accommodate a broad spectrum of Gen 3 Glock® slides and components, including models in 9mm, .40 S&W, .357 SIG, and others. This allows builders to create configurations resembling a G17, G34, G22, or several other popular models from a single, unified frame platform.
• Enhanced Ergonomic Design: Features an integrated extended beavertail and thumb ledge, promoting a consistently high and secure grip on the frame. This design helps manage recoil more effectively and improves overall control during firing sequences.
• Double-Undercut Trigger Guard: The sculpted trigger guard provides additional clearance for the support hand, facilitating a higher, tighter grip. This not only enhances comfort during extended range sessions but also contributes to improved shooting stability.
• Durable Polymer Construction: Manufactured from a robust, high-strength polymer, the frame offers an optimal balance of lightweight handling and long-term durability, designed to withstand the rigors of regular use.
• Jig-Ready 80% Design: Supplied as an unfinished receiver, it is intended for completion by the end-user with the appropriate tools and jig (sold separately). This provides a hands-on project that results in a uniquely personal firearm.
• Aggressive Texturing: Strategically placed texturing on the grip frame ensures a positive, non-slip hold in various environmental conditions, aiding in weapon retention and control.

Performance & Applications

The Polymer80 PF940v2 frame is the starting point for building a handgun suited to specific disciplines and uses. Its design directly supports enhanced performance in several key areas.

For the custom competition shooter, the frame’s inherent ergonomic improvements—like the thumb ledge and undercut guard—allow for faster, more natural index points and reduced perceived recoil. When paired with a G34-length slide or a ported barrel, it forms the basis of a highly capable USPSA or IDPA production-class firearm tailored to the shooter’s exact hand dimensions.

As a dedicated training platform, building a pistol on the PF940v2 frame creates a tool nearly identical in manual of arms to common service pistols, but with a grip angle and texture customized to the user. This allows for repetitive, high-volume practice with a firearm that fits better than a stock option, potentially improving fundamental skills. Furthermore, it serves as an excellent educational project for those wishing to gain an in-depth, mechanical understanding of how a modern striker-fired, semi-automatic pistol functions, from the sear engagement to the rail systems.
