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 platform for completing a custom subcompact build. Designed for compatibility with Gen 3 Glock 26 and 27 components, this 80% frame reduces machining time by approximately 45% compared to standard polymer frames, requiring only a drill press or hand drill and basic hand tools to finish. The kit includes the frame, jig, and all necessary drill bits, providing a complete solution for builders seeking a compact carry frame with full ambidextrous controls.

Overview

The Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) is machined from a proprietary reinforced polymer blend that exceeds OEM tensile strength specifications by 22%. The frame features an integrated trigger guard undercut, a high-friction textured grip panel, and a full-length accessory rail compatible with standard subcompact lights and lasers. The included jig is indexed to the frame with hardened steel alignment pins, ensuring 0.003-inch tolerance on critical pin holes during drilling. This 80% frame ships as a non-firearm component, requiring no serialization or background check for purchase, though final assembly must comply with all applicable federal and state laws.

Features & Specs

• Frame material: Reinforced polymer with 20% glass-fiber content; tensile strength 14,500 PSI; impact resistance 4.2 ft-lb at 73 degrees Fahrenheit
• Compatibility: Accepts all Gen 3 Glock 26 and 27 slide assemblies, barrels, trigger mechanisms, and magazine catches; magazine compatibility with 10-round, 12-round, and 15-round OEM magazines
• Jig system: Hardened 4140 steel jig with four alignment bushings; includes 3/32-inch, 1/8-inch, and 5/32-inch high-speed steel drill bits; jig retention via four 6-32 socket head screws

The Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) incorporates an integrated locking block system that eliminates the need for separate locking block installation. The frame’s internal rails are machined from 17-4 stainless steel, providing a Rockwell hardness of C42-C44. The trigger guard geometry is optimized for subcompact use, with a 0.25-inch relief cut for high-grip shooting positions. Total frame weight without components is 8.2 ounces; overall width is 1.18 inches.

Who It’s For

This Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) is intended for experienced firearm builders who possess a working knowledge of 80% frame completion procedures. It suits shooters requiring a subcompact platform for concealed carry, backup duty, or competition backup applications. The kit is ideal for individuals who prefer to customize their firearm’s grip texture, trigger geometry, and sight configuration from the frame up. Builders should have access to a drill press or a high-torque hand drill capable of 2,500 RPM, calipers for depth measurement, and a deburring tool for final finishing. The kit is not recommended for first-time 80% builders due to the precision required for proper sear engagement and trigger bar alignment.
