Polymer80 PF940SC Jig Kit for PF940SC Frame Blanks – 3mm

Product Overview

The Polymer80 PF940SC Jig Kit is an essential tooling package for the dedicated firearm enthusiast engaged in a personal build project. Designed specifically for the PF940SC 80% frame blank, this jig provides the precise guides and specialized bits required to accurately complete the machining process. This kit is intended for experienced hobbyists and builders who understand the intricacies of firearm construction and seek to create a custom, GLOCK® 26/27-compatible platform from an unfinished frame. Its primary use is to safely and correctly guide your drill and milling tools, transforming an 80% receiver into a functional frame ready for assembly with a compatible parts kit. By ensuring critical holes and cavities are positioned exactly to specification, this jig is fundamental to a successful build.

Key Features

• Precision-Engineered Two-Sided Jig: Crafted from a durable fiber-nylon composite, the jig features meticulously aligned guide holes and channels. It securely holds your PF940SC frame blank, providing the absolute reference needed for each machining step.
• Included Tooling for Completion: The kit contains the essential bits to begin, including the crucial 3mm drill bit specified for the fire control pin holes. This ensures you have the correct tool diameter for a critical phase of the build.
• Multi-Frame Durability: The robust composite construction isn’t just for precision; it’s built for longevity. When used as directed, this single jig can reliably guide you through the completion of up to three separate frame blanks.
• Model-Specific Design: This is not a universal jig. It is engineered exclusively for the Polymer80 PF940SC frame, guaranteeing compatibility and correct geometry for a GLOCK 26/27 platform build.
• Facilitates a Semi-Automatic Platform: The jig guides the machining required to create a functional frame for a semi-automatic handgun, following the original design intent and specifications.
• Streamlines the Machining Process: By consolidating the necessary guides into a single, easy-to-use fixture, it eliminates guesswork and reduces the potential for error, making the machining phase more efficient for the builder.

Performance & Applications

The Polymer80 PF940SC Jig Kit excels in specific, practical applications for the building community. Its performance is measured by the accuracy and repeatability it brings to a personal workshop.

First, it is the cornerstone for a custom compact build. A builder sourcing a PF940SC frame blank can use this jig to complete the frame, then pair it with a parts kit and slide to create a personalized everyday carry-style platform tailored to individual ergonomic and component preferences. Second, it serves an educational role for the machining hobbyist. The process of using the jig to drill and mill the frame provides hands-on understanding of firearm frame geometry and the relationship between fire control components. Finally, for those building multiple frames, the jig’s durability allows for consistent results across projects, ensuring each completed frame meets the same standard of quality.
