Product Overview

The Polymer80 PF940SC™ 80% Subcompact Frame and Jig Kit is a foundational component for the experienced firearms enthusiast 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 to complete. This kit is intended for individuals who enjoy the technical process of building and customizing their own equipment to precise specifications. The included precision jig and necessary bits provide the template and tools for the fabrication stage. The primary use of the completed frame is to serve as the core of a reliable, semi-automatic subcompact pistol for lawful purposes such as sport shooting, personal defense (where legally permitted), and as a dedicated platform for advanced customization.

Key Features

• Complete Fabrication-Ready Kit: Includes the 80% polymer frame, a durable aluminum jig, and the requisite drill bits. Everything you need to begin the precision machining process is in the box.
• Enhanced Ergonomic Design: Features an extended beavertail and thumb ledge for superior hand positioning and control. The double-undercut trigger guard allows for a higher, firmer grip, enhancing shooter comfort and stability.
• Optimized Grip Angle: Polymer80 engineers have updated the traditional grip geometry from 22 degrees to a modern 18-degree angle. This modification promotes a more natural point of aim and can improve shooting ergonomics for many users.
• Factory-Style Grip Texture: The frame comes with an aggressive, molded-in grip texture that provides a secure, non-slip surface without being overly abrasive, ensuring positive handling in all conditions.
• Glock® Gen 3 Compatibility: Guaranteed to work with standard Glock® 26/27 Generation 3 slides, parts kits, and magazines. This ensures a vast ecosystem of available components and aftermarket support for your build.
• Durable Polymer Construction: Made from high-strength polymer, the frame offers a lightweight yet robust foundation, finished in a clean stainless color that serves as an ideal base for further finishing or cerakoting.

Performance & Applications

Once completed with a slide, barrel, and internal parts kit, the PF940SC™ frame becomes the heart of a highly capable subcompact pistol. Its design supports specific, lawful applications for qualified individuals.

1. Concealed Carry Platform (Where Legally Permitted): The subcompact Glock® 26/27 form factor is renowned for its concealability. The PF940SC’s enhanced ergonomics—the undercut trigger guard and improved grip angle—make it a compelling choice for a builder seeking a tailored carry pistol that fits their hand perfectly, potentially improving draw consistency and comfort during extended wear.

2. Custom Project & Training Platform: For the technical shooter who values deep familiarity with their firearm, building from an 80% frame provides unparalleled insight into the function and fit of every component. This makes it an excellent project for advanced training in firearm mechanics. The completed pistol serves as a dedicated platform for practicing disassembly, maintenance, and trigger control on a system you built yourself.

3. Compact Sport Shooting: The reliable, semi-automatic action and compatibility with proven components make a completed build suitable for recreational target shooting and compact pistol courses. The design improvements aim to offer better shootability in a small package, which can be an advantage in dynamic shooting scenarios.
