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 kit is engineered for use with the Polymer80 PF45 80% frame blank, which is compatible with full-size, large-frame platforms like the GLOCK® 20 (10mm) and GLOCK 21SF (.45 ACP). The kit provides the precision-guided templates and necessary drill bits to accurately perform the milling and drilling operations required to transform an unfinished PF45 frame into a functional receiver ready for a parts kit assembly. It is intended for experienced hobbyists who understand the process, legal requirements, and responsibilities of building a firearm for personal use, where permitted by law.

Key Features

• Durable Fiber-Nylon Composite Construction: The two-sided jig is manufactured from a reinforced composite material that resists wear from router bits and drill bits, providing consistent guidance and maintaining critical tolerances through multiple uses.
• Multi-Use Design: Engineered for longevity, this jig is rated to complete up to three PF45 80% frame blanks, offering excellent value for builders planning multiple projects or those who value a robust, reusable tool.
• Complete Tooling for Critical Operations: Includes the specifically sized drill bits required for the PF45 frame: a 3mm bit for pin holes and a 4mm bit for the rear rail section and other larger apertures, matching the provided specifications.
• Precision-Guided Template System: The jig’s two-sided design securely clamps the PF45 frame blank, offering dedicated guides for both drilling precise pin locations and routing the firearm’s fire control cavity with accuracy.
• Platform-Specific Engineering: This is not a universal jig. It is meticulously designed for the exact dimensions and geometry of the Polymer80 PF45 frame, ensuring proper alignment for a reliable build when paired with a G20 or G21SF parts kit.
• Simplified Process: Consolidates the necessary specialized tooling into one kit, eliminating the need to source individual bits and templates separately, which helps ensure compatibility and correct hole sizing.

Performance & Applications

The primary application of the PF45 Jig Kit is to facilitate the safe and precise completion of a Polymer80 PF45 80% frame. Its performance is measured by the accuracy of the resulting holes and milled pockets, which directly impact the fit and function of the final assembled firearm.

A key use case is for the builder seeking a custom large-format semi-automatic platform. The PF45 frame accommodates the powerful 10mm and .45 ACP calibers, and using this dedicated jig ensures the frame is prepared to correctly accept all associated locking block, rail, and pin components from an OEM or aftermarket build kit. This precision is non-negotiable for reliable operation.

Furthermore, for enthusiasts interested in the mechanics of firearms, the process of using the jig—involving careful drilling, routing, and de-burring—provides a hands-on understanding of the frame’s role in the semi-automatic action. The jig’s design guides the user to create the necessary clearances and pin points that allow the slide, barrel, and trigger mechanism to interact seamlessly.
