Product Overview
The Polymer80 PF940SC™ 80% Subcompact Frame and Jig Kit is a foundational component for experienced firearms enthusiasts seeking a personalized, compact build. Designed to be compatible with Glock® 26 (9mm) and 27 (.40 S&W) Generation 3 components, this is a factory-unfinished “80%” frame. It is not a firearm and requires machining and assembly, making it a project for individuals who enjoy the hands-on process of building. The kit includes the polymer frame, a precision jig, and the necessary drill bits for completion. Its primary use is to serve as the core of a custom, subcompact semi-automatic pistol, ideal for those who value ergonomic customization and the practical knowledge gained from a build project.
Key Features
- Complete Fabrication Ready Kit: Includes the 80% polymer frame, a durable, precision-machined aluminum jig, and drill bits. This provides everything needed (minus tools and a parts kit) to professionally complete the frame.
- Enhanced Ergonomic Design: Features an extended beavertail and thumb ledge for superior hand positioning and control, reducing felt recoil and improving shot placement.
- Optimized Grip Geometry: Engineers upgraded the grip angle from the traditional 22 degrees to a more natural 18 degrees. This angle can improve pointability and comfort for many shooters.
- Double-Undercut Trigger Guard: Allows for a higher, firmer grip on the firearm, enhancing control and shooter comfort, especially important on a subcompact frame.
- Factory-Style Grip Texture: Provides a secure, non-slip surface that balances aggressive traction with everyday carry comfort, straight from the mold.
- Stainless Steel Rails & Polymer Frame: The frame is constructed from high-strength polymer with integrated stainless steel locking block and rear rail modules for durability and reliable slide operation.
Performance & Applications
Once properly completed and assembled with a Glock® Gen 3 parts kit and slide, the PF940SC™ frame forms the heart of a highly capable subcompact pistol. Its applications are defined by its compact size and customizable nature.
Custom Concealed Carry Foundation: For those who carry, this frame allows for a tailored fit. The undercut trigger guard and refined grip angle enable a deep, secure grip, which is critical for managing a small, snappy pistol. The result can be a carry piece that fits your hand better than any off-the-shelf option, potentially improving confidence and proficiency.
Technical Skill Development & Gunsmithing Project: This kit is an excellent project for the technically inclined shooter. The process of completing the frame—milling, drilling, and pinning—fosters a deeper understanding of the firearm’s mechanics and function. It’s a hands-on way to gain practical gunsmithing knowledge specific to the ubiquitous Glock platform.
Specialized Range or Competition Use: While subcompacts are often carry guns, a completed build using this frame can serve as a dedicated training tool. The ergonomic enhancements can make high-volume practice with a small firearm less fatiguing, and the project itself allows for the integration of aftermarket triggers or other custom internal components from the start.
