Polymer80 PF45 Jig Kit for PF45 Frame Blanks – 3mm

Product Overview

The Polymer80 PF45 Jig Kit is an essential tooling package designed for the dedicated firearms enthusiast engaged in frame completion projects. This specific jig is engineered for use with the Polymer80 PF45 80% frame blank, which is compatible with large-frame GLOCK® 20 (10mm) and 21SF (.45 ACP) platforms. It provides the precise guides and necessary hardware to accurately drill the required pin holes and create the frame cavity, transforming an 80% receiver into a functional frame ready for a parts kit assembly. This product is intended for experienced hobbyists and builders who understand the legal framework surrounding unfinished receivers and possess the technical aptitude for precision machining work. Its primary use is to facilitate a correct and secure completion process for your PF45 frame project.

Key Features

• Precision-Engineered Two-Sided Jig: The core component is a durable, two-sided jig that securely clamps your PF45 frame blank. It provides exact guide holes for drilling and routing, ensuring critical components like the trigger pin, locking block pin, and rear rail pin are positioned with factory-level accuracy for reliable function.
• Included Tooling for Completion: The kit comes with the specific drill bits required for the task, including the essential 3mm drill bit for pin holes and a 4mm drill bit for other frame operations, as specified for the PF45 model. This eliminates guesswork in tool selection.
• Durable Fiber-Nylon Composite Construction: Made from a tough fiber-reinforced material, this jig is built to withstand the pressures of drilling and milling. This robust construction allows the jig to be used to complete up to three frames without loss of precision, offering extended value.
• Model-Specific Design for PF45 Frames: Unlike universal jigs, this tool is custom-designed for the PF45 frame geometry and its semi-automatic fire control system. This ensures all cuts and holes align perfectly with a GLOCK 20 or 21SF parts kit, leading to a smoother build process.
• Comprehensive Single-Kit Solution: Contains all the specialized jig components and drill bits needed to finish your PF45 frame blank. You supply the frame, the parts kit, a drill press or router, and basic workshop safety equipment.

Performance & Applications

The Polymer80 PF45 Jig Kit excels in specific, practical applications for the building community. Its performance is measured by the accuracy and repeatability it brings to a complex task.

Large-Caliber Pistol Builds: This is the definitive tool for builders working on a Polymer80 PF45 frame, the platform for constructing pistols in potent calibers like 10mm Auto and .45 ACP. The jig ensures the robust polymer frame is machined to correctly accept the larger locking block and slide components unique to these big-bore platforms, where tolerances are critical for managing increased recoil forces.

Precision Hobbyist Manufacturing: For the skilled hobbyist, this jig transforms a manual frame completion project from a potentially error-prone undertaking into a controlled, repeatable process. It guides the builder in creating a clean, professional-grade frame cavity and perfectly aligned 3mm pin holes, which are fundamental for a safe and reliable final assembly. This application is about achieving a factory-fit finish through careful, guided work.
