Polymer80 PF940SC 80% Pistol Frame Only

The Polymer80 PF940SC 80% Pistol Frame Only represents a critical component for builders seeking a compact, subcompact-compatible platform. This frame is the foundational element for constructing a custom pistol chambered in 9mm or .40 S&W, requiring the end user to complete the final machining steps. As an 80% frame, it is not a finished firearm and does not include a serial number, making it an ideal choice for hobbyists and gunsmiths who prefer to complete their own builds. The PF940SC designation indicates a subcompact size, designed to accept standard Glock 26 and 27 magazines, providing a balance of concealability and capacity. When paired with a compatible slide assembly, this frame delivers a reliable, ergonomic grip angle and a textured surface for positive control.

Overview

The Polymer80 PF940SC 80% Pistol Frame Only is a precision-machined polymer component that serves as the starting point for a fully customized pistol. Unlike completed frames, this 80% variant requires the builder to remove three specific material bridges using a router or drill press, then drill and tap the trigger housing pin holes. The frame is manufactured from a high-strength, impact-resistant polymer blend that withstands repeated firing cycles. It includes a stainless steel rear rail system and a locking block assembly, both of which are pre-installed to reduce assembly complexity. The frame is compatible with standard Gen 3 Glock 26/27 components, including slides, barrels, trigger assemblies, and magazines. This design allows for a straightforward build process while maintaining the durability expected from a Polymer80 product.

Features & Specs

This frame is engineered to meet the specifications of the PF940SC platform. The following features define its construction and compatibility:

• Material: Reinforced polymer body with a textured grip surface for enhanced traction in wet or gloved conditions.
• Rail System: Integrated stainless steel front and rear rails, pre-installed for precise slide alignment and reduced friction during cycling.
• Compatibility: Accepts Gen 3 Glock 26/27 slide assemblies, barrels, recoil springs, and lower parts kits. Magazine compatibility includes standard 10-round and extended magazines.
• Trigger Guard: Standard Glock-style trigger guard with a slight undercut for improved high-hand grip placement.
• Finish: Matte black texture with a non-reflective surface to minimize glare during low-light conditions.

Additional specifications include a weight of approximately 2.7 ounces for the bare frame, a width of 1.26 inches at the grip, and an overall length of 6.5 inches. The frame accepts a standard 3.46-inch barrel length, consistent with subcompact designs. The magazine well is flared slightly for faster reloads, though it does not accept flared baseplates without modification.

Who It’s For

The Polymer80 PF940SC 80% Pistol Frame Only is intended for experienced builders who are comfortable with basic tooling and firearm assembly. This product is not suitable for first-time firearm owners or those unfamiliar with 80% frame completion. It is designed for individuals who want to create a subcompact pistol with a personalized grip, trigger, and slide combination. The frame appeals to hobbyists who enjoy the mechanical process of drilling, filing, and fitting components. It is also a practical choice for those who wish to build a pistol without serial number registration, provided all local, state, and federal laws are followed. Users should have access to a drill press, router, or hand drill, along with appropriate jigs and reamers, to complete the frame successfully.

Shipping & FFL

Important: The Polymer80 PF940SC 80% Pistol Frame Only is classified as a non-firearm item under current federal regulations (ATF determinations pending legal changes). As a result, this product does not require transfer through a Federal Firearms License (FFL) dealer for shipment. It can be shipped directly to your residential address. However, customers are solely responsible for verifying compliance with all applicable state and local laws regarding 80% frames, including any restrictions on possession or completion. Some states and municipalities prohibit the ownership or transfer of unserialized frames. By purchasing this product, you acknowledge that you are legally permitted to own and complete this frame in your jurisdiction. No further FFL involvement is necessary for this transaction, but we strongly recommend consulting local law enforcement or an attorney if you have questions about legality.
