Description
The Polymer80 PF940SC is an 80% frame kit engineered for building a compact Glock 26/27 Gen3 platform. This is the foundation for a custom, serialized build, offering superior ergonomics and a full grip over the factory frame. It’s for the enthusiast who values a hands-on project and a tailored fit. We’ve had this kit on our shelves since Q1 2025, and its low return rate tells us builders know what they’re getting.
Stand-Out Features
- Enhanced Grip & Ergonomics: Aggressive front and rear strap texturing provides a secure, non-slip hold, a noticeable upgrade from the factory feel.
- Full-Size Grip on a Compact Frame: The design eliminates the finger groove hump, allowing for a full, comfortable grip on the subcompact G26/27 platform.
- Precision Jig Included: The included, durable polymer jig is essential for accurately drilling the required pin holes and completing the frame.
- Complete Hardware Kit: Comes with all necessary pins, a locking block, and a rear rail module for assembly—no need to source additional parts.
- Robust Polymer Construction: Made from reinforced polymer for durability and a lightweight build, coming in at just 6.7 ounces on our scale.

Your Questions Answered
What tools do I need to complete this 80% frame?
You will need a drill press or a reliable hand drill, a set of drill bits (3mm and 4mm are typical), and quality files or a Dremel tool to clean the pin holes and channel. The included jig guides the drilling process.
Will this frame accept Gen4 or Gen5 slides?
This frame is designed specifically for Gen3 components. Our staff notes that while Gen4 slides can sometimes fit, the lockup is slightly tighter and not guaranteed. For optimal performance and reliability, use Gen3-compatible slides and parts.
Is the rear rail module pre-installed?
No. The rear rail module is included in the kit but must be installed during the build process. This allows for precise fitting and ensures proper slide-to-frame alignment once the frame is completed.
