Polymer80 PF940C Jig Kit for PF940C Frame Blanks – 3mm

Description

Product Overview

The Polymer80 PF940C Jig Kit is an essential tooling package designed for the precise completion of a PF940C 80% frame blank. This kit is engineered for hobbyists, firearms enthusiasts, and skilled DIY builders who are engaged in the personal fabrication of a polymer frame for a GLOCK® 19-compatible handgun. Its primary use is to provide the guided templates and specialized drill bits required to accurately cut the frame rail slots and drill the critical pin holes, transforming an unfinished 80% receiver into a functional firearm frame ready for parts kit assembly. The process demands attention to detail and basic workshop skills, and this jig is the cornerstone tool that makes it achievable with professional results.

Key Features

• Durable Fiber-Nylon Composite Construction: The jig itself is manufactured from a rugged, glass-reinforced composite material that withstands the pressures of drilling and milling, offering superior longevity compared to standard polymer jigs.
• Multi-Frame Capability: Engineered for reuse, this single jig kit is robust enough to be used to successfully complete up to three separate PF940C frame blanks, providing excellent long-term value.
• Complete Tooling for Critical Operations: Includes the specific drill bits required for the task: a 3mm bit for drilling the trigger and locking block pin holes, and a 4mm bit for the rear rail pin hole, matching the specified caliber of the frame’s design.
• Two-Sided Precision Jig: Features a comprehensive, two-sided milling and drilling guide that securely houses the PF940C frame blank. It ensures correct alignment for all necessary operations, from the front and rear rail channel cuts to the precise drilling of all pin holes.
• GLOCK 19 Compatibility: The jig is specifically designed for the PF940C frame, which is engineered to accept standard GLOCK 19 generation 3 parts kits, ensuring a wide availability of components for the final build.
• Simplified Process Guidance: When used in conjunction with Polymer80’s official instructions and standard workshop tools (like a hand drill and rotary tool), it provides a clear, guided path to completing your frame with confidence.

Performance & Applications

The Polymer80 PF940C Jig Kit excels in specific, practical applications for the responsible builder. Its performance is defined by the accuracy and repeatability it brings to the frame completion process.

Personalized Firearms Fabrication: For the individual seeking to build a custom, GLOCK 19-compatible handgun from the ground up, this jig is the critical first step. It allows for the hands-on completion of the frame, which can then be paired with a chosen slide, barrel, and internal components to create a personalized firearm that meets specific ergonomic or performance preferences. The jig ensures the foundational element—the frame—is machined to exacting specifications.

Advanced Gunsmithing Education & Skill Development: This kit serves as an excellent project for those looking to deepen their practical understanding of semi-automatic pistol mechanics and polymer frame fabrication. The hands-on process of using the jig to drill and mill teaches valuable skills in jig-and-fixture use, material removal techniques, and the importance of precision in firearms assembly, all within a controlled, project-based context.

Frame Replacement or Multi-Build Projects: Given its durability and multi-frame design, this jig is an ideal investment for a builder planning more than one PF940C-based project. Whether constructing a dedicated competition frame, a compact carry build, or simply maintaining a spare, the same jig kit provides consistent, reliable guidance across multiple builds, ensuring uniformity and quality in each completed frame.
