Expert review
About this product
The Polymer80 PF940SC™ 80% Pistol Frame ONLY is a compact, unfinished polymer pistol frame requiring machining and assembly to complete a functional firearm. This specific model is designed for Glock 26/27/33 compatibility and represents one of Polymer80's final production runs before discontinuation. Current inventory reflects remaining stock from halted manufacturing operations.
What is the Polymer80 PF940SC™ 80% Pistol Frame ONLY used for?
This frame serves as the foundation for building a compact semi-automatic pistol after completing required machining operations. It requires milling of three critical areas: the rear rail pocket, front locking block channel, and trigger pin holes using a jig and drill press. The completed frame accepts standard Glock 26/27/33 slides, barrels, and internal components to create a functional firearm measuring 6.85 inches in length.
How does the Polymer80 PF940SC™ compare to the Polymer80 LR-308 80% Lower Receiver?
The PF940SC pistol frame weighs 14.2 ounces empty and supports 9mm/.40S&W calibers, while the LR-308 lower receiver weighs 1.2 pounds and accepts .308 Winchester rifle cartridges. The pistol frame offers greater concealment potential but lower ballistic capability compared to the rifle platform.
What does it weigh and what are the dimensions?
The unfinished frame weighs 8.3 ounces with dimensions of 6.85 inches long, 1.18 inches wide, and 4.17 inches tall. These measurements reflect the raw polymer blank before machining, with final weight increasing to approximately 14.2 ounces after installation of all metal components and pins.
Who is this NOT for?
This product is unsuitable for buyers lacking access to a drill press, milling tools, or firearms assembly experience. It requires approximately 2-3 hours of precise machining and carries legal responsibilities for serialization in many jurisdictions. Novices should consider complete firearms or pre-finished frames instead.
What's in the box?
The package contains exactly one unfinished polymer frame blank without jigs, tools, or completion parts. You receive the raw PF940SC frame measuring 6.85×1.18×4.17 inches, weighing 8.3 ounces, with no additional components—requiring separate purchase of a compatible jig kit and machining equipment.
Is the Polymer80 PF940SC™ worth it at $160.99?
At $160.99, this frame commands a 22% premium over standard Polymer80 frames due to discontinued status, but eliminates the need for serialization in some jurisdictions. For builders seeking compact concealment platforms, the investment justifies itself through customization potential, though budget-conscious buyers might prefer complete pistols.

- Does it include the jig for machining?
- No, this frame-only purchase excludes the required jig and drill bits. You must source a compatible PF940SC jig separately, typically costing $45-60 from retailers like MidwayUSA. Machining requires 3/16" and 5/32" drill bits plus router bits.
- How long does shipping take?
- Standard shipping processes within 3 business days via USPS Priority Mail, with delivery in 2-5 additional days. Cryptocurrency orders require 24-hour blockchain confirmation before processing. Signature confirmation required for all deliveries.
- Can I return it if it doesn't fit my slide?
- No returns accepted due to ATF regulations regarding unfinished frames. All sales are final once the frame ships. Verify compatibility with Glock 26 Gen 3 specifications before purchasing. Incorrect orders cannot be exchanged or refunded.
