Polymer80 PF940C Jig Kit for PF940C Frame Blanks – 3mm

Product Overview

The Polymer80 PF940C Jig Kit is an essential tooling package for the firearms enthusiast engaged in a custom build project. Designed specifically for the PF940C 80% frame blank, this kit provides the precision-guided templates and specialized drill bits required to properly machine the frame to a completed state. This product is intended for experienced hobbyists and builders who understand the process of completing a frame for personal use and seek a reliable, repeatable method. Its primary use is to accurately guide the milling and drilling operations on a Polymer80 PF940C frame, transforming it into a functional receiver compatible with standard GLOCK® 19 Gen 3 components. When paired with a parts kit, it allows for the creation of a custom, semi-automatic pistol.

Key Features

• Durable Fiber-Nylon Composite Construction: The jig itself is manufactured from a tough, fiber-reinforced material that withstands the pressures of machining, offering the rigidity needed for precise cuts and hole placement while providing a lifespan capable of completing multiple frames.
• Complete Tooling for Frame Completion: This kit includes the essential guided tools: a two-sided milling jig and the correct drill bits. Specifically, it contains the necessary 3mm drill bit for pin holes and a 4mm drill bit for other critical frame components, as outlined in the product specifications.
• Multi-Frame Capability: Engineered for longevity, the robust design of the jig allows it to be used to successfully complete up to three separate PF940C frame blanks, offering significant value for builders planning multiple projects.
• Precision Engineering for Compatibility: Every guide hole and channel is machined to exacting tolerances to ensure that your finished frame will properly accept aftermarket or OEM GLOCK 19 Gen 3 upper parts kits, slides, and barrels for reliable function.
• Two-Sided Jig Design: The jig’s design incorporates both top and bottom guidance in a single unit, facilitating a more streamlined process for drilling the required pin holes and creating the recoil spring channel with consistent alignment.
• Simplified Process Guidance: While the kit provides the physical tools, it is designed for use alongside detailed, widely available instructional resources, enabling a builder to systematically progress through the frame completion steps with confidence.

Performance & Applications

The Polymer80 PF940C Jig Kit excels in specific, practical applications for the dedicated builder. Its performance is measured by the accuracy of the finished frame and the repeatability of the process.

First, it serves as the foundational tool for a custom GLOCK 19-compatible build. A builder starts with an inert PF940C frame blank and uses this jig with a standard drill press or router (tools not included) to create the fire control cavity and drill the pin holes. This application is ideal for those seeking a personalized handgun with specific ergonomics or aesthetics not available in factory offerings, all while gaining a deeper understanding of the platform’s mechanics.

Second, this kit is invaluable for batch building or prototyping. Given its rated durability for multiple uses, a workshop or an individual can efficiently complete several frames in succession. This is useful for builders who wish to create frames with different stippling patterns, colors, or slight modifications for comparison, or for those assisting fellow enthusiasts under proper guidance and within legal boundaries.
