Polymer80 PF940C Jig Kit For PF940C Frame Blanks

This jig kit is a dedicated tooling solution designed specifically for the Polymer80 PF940C compact frame blank. Manufactured to OEM specifications by Polymer80, this kit provides the precise alignment surfaces and guide paths required to complete a PF940C frame from its raw polymer state to a functional, serialized component. The kit includes all necessary drill bits, end mills, and alignment fixtures to facilitate the machining of the trigger housing pocket, pin holes, and front locking block recess.

Overview

The polymer80 pf940c jig kit for pf940c frame blanks is the official fixture set engineered to mate exclusively with the PF940C frame geometry. Unlike universal jigs, this kit features a contoured base that conforms to the frame’s internal rails and dust cover profile, eliminating lateral play during drilling operations. The jig body is constructed from glass-filled nylon to resist deformation under repeated torque loads from hand drills or drill presses. Each kit is packaged as a complete set with three hardened steel drill bits (3mm, 4mm, and 5mm), a 3/16-inch end mill for the trigger housing pocket, and a stainless steel alignment pin set. All cutting tools are pre-sharpened and coated with a titanium nitride layer for extended service life across multiple frame completions.

Features & Specs

This polymer80 pf940c jig kit for pf940c frame blanks incorporates several engineering details that distinguish it from third-party alternatives. The jig’s primary locating pin matches the PF940C’s rear rail module geometry to within 0.002 inches of tolerance, ensuring that the trigger housing pocket is cut concentric to the frame’s bore axis. The kit includes a removable chip tray that collects polymer swarf during machining, reducing cleanup time. Below are the critical specifications and included components:

• Jig body: glass-filled nylon with stainless steel locating pins; overall dimensions 7.5 x 3.2 x 2.1 inches; weight 0.7 lbs
• Cutting tools: one 3/16-inch end mill (four-flute, TiN-coated), one 3mm drill bit, one 4mm drill bit, one 5mm drill bit; all bits feature 135-degree split point tips
• Alignment fixtures: two steel dowel pins (3mm diameter, 1.5 inch length), one rear rail alignment block, one front locking block spacer

Additional technical details include a molded-in depth stop at 1.25 inches for the end mill, preventing over-penetration into the trigger guard area. The jig incorporates four threaded brass inserts for mounting hardware, allowing the user to clamp the jig to a workbench without damaging the polymer body. The kit is compatible with both manual hand drills and low-speed drill presses operating between 300 and 800 RPM.

Who It’s For

This polymer80 pf940c jig kit for pf940c frame blanks is intended for individuals who possess a PF940C frame blank and require a purpose-built tool to complete the machining steps. The kit is suitable for experienced hobbyists who have basic familiarity with hand drill operation and safe workholding practices. It is also appropriate for gunsmiths who need a repeatable fixture for multiple frame builds, as the hardened steel bits can be replaced independently. Users should have a clean, well-lit work area, a drill with a 3/8-inch chuck capacity, and eye protection. This kit is not designed for use with frames from other manufacturers or for the PF940C full-size variant. Completion of the frame requires the user to possess a serialized frame blank and comply with all applicable federal, state, and local laws regarding firearm manufacture.
