Polymer80 PF940SC Jig Kit for PF940SC Frame Blanks – 3mm

Product Overview

The Polymer80 PF940SC Jig Kit is the essential tooling required to professionally complete a PF940SC 80% frame blank. This kit is designed for the experienced firearms enthusiast or builder who understands the process of creating a frame for personal use. Its primary function is to accurately guide your drill and milling tools to transform an inert Polymer80 PF940SC frame blank into a functional firearm frame, specifically one compatible with GLOCK® 26 and 27 components. By providing the critical reference points for the 3mm pin holes and frame rail cavities, this jig ensures your machining work meets the precise specifications needed for reliable assembly and operation.

Key Features

• Durable Fiber-Nylon Composite Construction: Engineered for repeated use, the tough jig material maintains dimensional stability and can be used to complete multiple frames, providing excellent long-term value.
• Complete Machining Guidance: The two-sided jig design securely holds your PF940SC frame blank, offering all necessary guides for drilling the critical 3mm pin holes and milling the frame rail channels.
• Includes Essential Tooling: Comes with the specific drill bits required for the job, including the crucial 3mm bit for pin holes and a 4mm bit for other operations, ensuring you have the correct tools to start.
• Precision Engineered for the PF940SC: Jig is machined to exacting tolerances specific to the PF940SC frame geometry, promoting correct alignment and function for a G26/G27-compatible build.
• Multi-Use Capacity: The robust construction allows the jig to be used for completing up to three 80% frame blanks, making it a practical investment for builders.
• Simplified Process: Consolidates the necessary guides into a single, intuitive system, reducing setup time and potential for error during the machining phase of your build.

Performance & Applications

The Polymer80 PF940SC Jig Kit performs one core task with precision: enabling the safe and accurate completion of an 80% receiver. Its application is specific and vital for the builder.

Primary Use Case: The definitive application is completing a Polymer80 PF940SC frame blank. This involves using the jig in a drill press or with a hand drill (with extreme care) to drill the front and rear locking block pin holes, as well as the trigger pin hole, all to the specified 3mm diameter. The jig then guides the milling of the frame rail channels, a step critical for the proper fit and slide cycling of the finished firearm.

Project Enabler: This jig is the gateway component for a custom G26/G27-compatible build. Without it, the 80% frame blank cannot be correctly machined. It allows a builder to take a raw, unfinished frame and progress to the assembly stage where slide, barrel, and internal parts kits are installed, resulting in a complete, functional pistol built to personal specifications.
