Polymer80 PF940C Jig Kit for PF940C Frame Blanks

Building your own compact frame has never been more straightforward. The Polymer80 PF940C Jig Kit for PF940C Frame Blanks provides the precision tooling required to complete a PF940C frame blank with confidence. Designed by Polymer80 for their compact frame platform, this jig kit delivers the alignment, drilling guides, and pinning templates needed to finish a frame from a raw blank state. Whether you are a first-time builder or an experienced hobbyist, this kit eliminates guesswork and reduces the risk of misalignment during the assembly process.

Overview

The Polymer80 PF940C Jig Kit for PF940C Frame Blanks is a dedicated machining and assembly aid engineered specifically for the PF940C compact frame. It includes all necessary drill bits, alignment pins, and guide blocks to convert a PF940C blank into a functional lower receiver. The jig body is constructed from impact-resistant polymer and features clearly marked drill points for the trigger housing pin, rear rail pin, and front locking block pin. This kit is the only jig set currently offered by Polymer80 that is purpose-built for the PF940C compact platform, ensuring a precise fit with no modification required.

Features & Specs

• Manufacturer: Polymer80. Category: Frames. Compatible exclusively with PF940C compact frame blanks.
• Includes hardened steel drill bits (3/32″, 1/8″, 5/32″) with pilot tips for chatter-free entry into polymer and metal rail inserts.
• Integrated indexing system with raised alignment tabs and depth stops to prevent over-drilling and frame damage.

The jig kit also features a modular clamping block system that secures the frame blank in three axes. This reduces lateral movement during drilling and allows for consistent hole placement across multiple builds. The included stainless steel alignment pins are ground to within 0.001-inch tolerance for reliable rail and locking block insertion.

Who It’s For

This kit is intended for individuals who possess a PF940C frame blank and wish to complete it using standard hand tools such as a drill press or handheld drill. It is suitable for builders who want a dedicated jig rather than a universal system, as the PF940C-specific design eliminates the need for shims or adapters. The Polymer80 PF940C Jig Kit for PF940C Frame Blanks is also appropriate for those who have previously completed other Polymer80 frames and want a streamlined workflow for the compact platform. No gunsmithing experience is required, but users should be comfortable following step-by-step instructions and using basic shop tools.
