Polymer80 PF940SC 80% Pistol Frame Only

The Polymer80 PF940SC 80% Pistol Frame Only represents a precision-engineered foundation for building a compact, subcompact-sized handgun. As an unfinished 80% frame, this unit requires final machining, assembly, and serialization to become a functional firearm. Designed for builders who prioritize control over the manufacturing process, the PF940SC is the smallest frame in the Polymer80 lineup, optimized for concealed carry and close-quarters utility. This frame is compatible with Glock 26, 27, 28, 29, and 33 slide assemblies and lower parts kits, offering extensive customization potential without the regulatory footprint of a completed receiver.

Overview

The polymer80 pf940sc 80% pistol frame only is a raw, unpolymerized blank that demands end-user finishing. It arrives as a single-piece polymer structure with integrated rail system, trigger guard, and grip housing, but lacks the fire-control pocket, rear rail block, and pin holes. The frame is manufactured from a proprietary glass-reinforced nylon polymer that resists impact, chemical solvents, and thermal fatigue. Each frame is CNC-molded to tight tolerances, ensuring consistent alignment with factory-spec components. The PF940SC is intended for hobbyist builders, gunsmiths, and enthusiasts who wish to complete a firearm under their own supervision, adhering to all applicable federal, state, and local laws regarding self-manufactured firearms.

Features & Specs

• Frame Material: Proprietary glass-reinforced nylon polymer with UV stabilizers and impact modifiers for dimensional stability.
• Rail System: Integrated dust cover with steel-reinforced front rail insert; rear rail block is user-installed after milling the fire-control pocket.
• Compatibility: Accepts standard Glock 26/27/28/29/33 slide assemblies, barrel, recoil spring, and lower parts kits (OEM or aftermarket).
• Grip Geometry: Textured grip panels with aggressive stippling pattern; interchangeable backstrap system for palm swell adjustment.
• Build Requirements: Requires drilling of three pin holes (trigger, hammer, and trigger housing), milling of the block pocket, and finishing of the frame rails. No serial number is present; builder must apply one per ATF guidelines if intended for transfer or sale.

The polymer80 pf940sc 80% pistol frame only ships as a bare blank with no jig, bits, or hardware. Builders must source a Polymer80 PF940SC-specific jig or use a universal 80% frame jig kit. The frame weighs approximately 2.4 ounces before finishing. The magazine well is flared for faster reloads, and the trigger guard is undercut for high-grip positioning. All dimensions match factory subcompact Glock frames, ensuring holster compatibility with standard 26/27 holsters.

Who It's For

This frame is designed for individuals who understand the mechanical and legal requirements of completing an 80% firearm. The polymer80 pf940sc 80% pistol frame only is ideal for experienced builders seeking a subcompact platform for concealed carry, backup duty, or range use. It appeals to those who prefer to hand-fit components, test trigger geometry, and customize grip texture without purchasing a fully serialized firearm. Law enforcement officers, competitive shooters, and hobbyist gunsmiths will appreciate the ability to control every aspect of the build, from barrel length to trigger pull weight. The PF940SC is not recommended for first-time builders due to the precision required for fire-control pocket milling and pin hole alignment. Users must possess or have access to a drill press, end mills, calipers, and a jig system to complete the frame safely.

Shipping & FFL

The polymer80 pf940sc 80% pistol frame only is classified as a non-gun component under federal law because it is not a finished receiver. Therefore, it does not require transfer through a Federal Firearms License (FFL) dealer when purchased as an 80% blank. However, the purchaser bears full responsibility for complying with all state and local regulations regarding the possession, completion, and serialization of 80% frames. Some states, including but not limited to California, New York, New Jersey, Connecticut, Washington, and the District of Columbia, restrict or prohibit the sale of unfinished frames. By purchasing this product, you confirm that you are legally eligible to own a firearm in your jurisdiction and that you will not transfer the completed frame to any person prohibited from possessing firearms. Polymer80 and this retailer assume no liability for misuse or noncompliance. All sales are final. This product ships via ground service with adult signature required. No returns or exchanges are accepted on 80% frames due to their unfinished, serialized nature once work begins.
