Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible)

The polymer80 pf940sc™ 80% subcompact frame and jig kit (glock® 26/27 compatible) represents a precision-engineered solution for the experienced builder seeking a compact, concealable platform. This kit provides the foundational components necessary to complete a legally compliant, non-serialized frame for use with Gen 1 through Gen 3 Glock 26 and Glock 27 upper assemblies. Designed for the subcompact market, this frame offers a shortened grip length and a 10-round magazine capacity, maximizing concealability without sacrificing the ergonomic improvements inherent in the Polymer80 design.

Overview

This kit includes the PF940SC 80% subcompact frame and the corresponding multi-jig system. The frame is constructed from a proprietary high-impact, glass-reinforced polymer, offering structural integrity comparable to factory frames while allowing the end user to complete the frame rails, trigger housing pocket, and pin holes. The included jig system ensures precise alignment during the milling and drilling process, reducing the margin of error for the builder. Every polymer80 pf940sc™ 80% subcompact frame and jig kit (glock® 26/27 compatible) ships with the necessary drill bits, end mill, and step-by-step instructions to facilitate a successful build.

Features and Specs

• Frame Geometry: Subcompact grip length with a 10-round flush-fit magazine capacity. The frame incorporates an integrated beavertail, a textured front and rear grip surface, and an undercut trigger guard for improved high-hand hold placement.
• Material Composition: Proprietary glass-reinforced nylon polymer. This material provides impact resistance, UV stability, and dimensional consistency throughout the machining process. The frame is black in color with a matte finish.
• Compatibility: Accepts all Gen 1 through Gen 3 Glock 26 and Glock 27 slides, barrels, and lower parts kits. Compatible with standard Glock 26/27 magazines and aftermarket magazine extensions designed for the subcompact platform. The frame uses a standard Glock 26/27 locking block and trigger mechanism housing.
• Jig System: The included multi-jig is constructed from machined aluminum and high-tolerance polymer. It indexes off the frame’s internal geometries to ensure proper alignment of the three pin holes, the front and rear rail pockets, and the trigger housing pocket. The jig is reusable for subsequent builds.
• Machining Requirements: Requires the builder to remove approximately 0.050 inches of material from the front and rear rail pockets, drill three 3mm pin holes, and clear the trigger housing pocket. All necessary tooling is included in the kit.
• Manufacturer Specifications: This product is manufactured by Polymer80 under the category of Frames. The frame is sold as an unfinished, non-functional component and requires final machining and assembly by the end user.
