Polymer80 PF940C™ 80% Pistol Frame ONLY – 9mm

Product Overview

The Polymer80 PF940C™ 80% Pistol Frame is the foundational component for building a compact, 9mm semi-automatic pistol compatible with a wide array of Glock® 19 parts and aftermarket components. Designed for the experienced firearms enthusiast and hobbyist builder, this frame is sold as an unfinished “80%” receiver, meaning it requires machining and assembly to be completed. This project is ideal for individuals who seek a deep understanding of their firearm’s mechanics, desire a personalized fit and feel, or simply enjoy the process of precision building. The primary use of the completed firearm is for lawful sporting, range training, and home defense, where its compact 9mm chambering offers a balance of controllability and capacity.

Key Features

• Glock® 19 Compatibility: Engineered to accept standard Glock® 19 generation 3 parts kits, slides, barrels, and magazines, providing unparalleled access to the world’s largest aftermarket support system.
• Enhanced Ergonomic Design: Features an integrated extended beavertail and pronounced thumb ledge to promote a consistent, high grip for better recoil management and control.
• Double-Undercut Trigger Guard: Provides additional clearance for the support hand, allowing for a higher, firmer grip and enhanced shooter comfort, especially during extended range sessions.
• Durable Polymer Construction: Manufactured from a robust, glass-reinforced polymer substrate, offering a proven balance of lightweight durability and long-term reliability under use.
• Unfinished 80% Frame: Requires the end user to complete the final machining steps (using a separate jig and tools), making it a project for those interested in the build process and customization from the ground up.
• Multiple Color Options: Available in various finishes, allowing for personalization and aesthetic distinction in your final build.

Performance & Applications

The completed PF940C™ build excels in specific roles where its compact size and 9mm chambering are advantageous. For concealed carry training, the frame’s ergonomic enhancements, like the undercut trigger guard, allow for more efficient draw-stroke practice and comfortable all-day dry fire sessions, building essential muscle memory. As a dedicated home defense platform, once legally assembled into a functioning firearm, its compatibility with proven Glock® 19 components and ample accessory rail for lights ensures a reliable and adaptable system. Finally, for the shooting sports enthusiast, this frame serves as an excellent platform for USPSA Carry Optics or IDPA CCP division, where its customizable grip and trigger geometry can be tuned to match competitive preferences precisely.
