The Polymer80 PF940C 80% Pistol Frame Only represents a foundational component for builders seeking a compact, custom firearm platform. This unfinished frame, manufactured to Polymer80’s exacting specifications, requires machining and finishing to complete the build. As a Category: Frames product from Polymer80, it offers the structural integrity and ergonomic design expected from a leading manufacturer in the 80% pistol frame market. The PF940C variant is engineered for those who prioritize precision, modularity, and hands-on assembly without compromising on materials or build quality.
Overview
The Polymer80 PF940C 80% Pistol Frame Only is an unfinished polymer frame designed for use with compact pistol slides and barrels. It incorporates the signature Polymer80 front and rear slide serrations, an integrated trigger guard undercut, and a high-traction texture on the grip for positive control. The frame is manufactured from impact-resistant, glass-reinforced nylon polymer, ensuring long-term durability under repeated use. This 80% frame requires completion using a drill press, hand tools, and finishing files to fully machine the fire control pocket and pin holes. It does not include a trigger, slide, barrel, or lower parts kit.
Features & Specs
- Material & Construction: Glass-reinforced nylon polymer with a matte black finish; precision-molded to Polymer80 tolerances for compatibility with compact GLOCK-style Gen 3 parts.
- Ergonomics & Grip: Textured grip panels with a raised backstrap; integrated beaver tail and trigger guard undercut for improved hand placement and recoil management.
- Rail System: Full-length dust cover with a built-in recoil spring channel; includes a steel-reinforced front rail section for slide stability.
This frame is compatible with slides and barrels designed for compact 9mm, .40 S&W, and .357 SIG builds. The overall length measures 7.5 inches, with a grip circumference of 5.2 inches and a weight of approximately 2.8 ounces. The Polymer80 PF940C 80% Pistol Frame Only requires the user to complete the fire control pocket machining, drill the three pin holes, and finish the trigger guard area. All jigs, drill bits, and finishing tools are sold separately.
Who It’s For
This product is intended for experienced firearm builders, hobbyists, and custom gunsmiths who possess the necessary tools and knowledge to complete an 80% frame. The Polymer80 PF940C 80% Pistol Frame Only is ideal for individuals seeking a personalized compact pistol platform, whether for target shooting, range use, or as a specialized project.
