PF940SC Complete Frame Kit for Compact Builds

If you are looking to build a compact pistol from the ground up, the PF940SC frame is one of the most practical starting points on the market right now. This is the same platform that has earned a strong reputation among DIY firearm enthusiasts for its straightforward assembly process and reliable performance. Whether you are completing your first build or adding another caliber to your collection, the PF940SC delivers the foundation you need without unnecessary complexity.

Overview

The PF940SC is a compact, subcompact frame designed for use with a wide range of aftermarket slides and parts kits. It is built from a high-strength polymer composite that holds up well under regular use and maintains its rigidity over time. The frame comes as a complete kit, which means you get the frame itself along with the necessary jig, bits, and rails to finish your build at home. This is not a pre-assembled frame; it requires some hands-on work, but the process is well-documented and achievable with basic tools. The PF940SC is chambered for 9mm, .40 S&W, and .357 SIG, giving you flexibility depending on your preferred caliber and slide selection.

Features & Specs

The PF940SC stands out because of its ergonomic design and compatibility with standard aftermarket components. The frame includes an integrated locking block and front and rear rail systems that are already installed, saving you the most tedious part of the build. The grip texture is aggressive enough to maintain control in wet or gloved conditions, but not so rough that it chews up your hands during a range session. Here are the key specifications you need to know:

• Frame material: High-strength, impact-resistant polymer composite with a matte black finish
• Compatibility: Works with compact and subcompact slides (typically 3.6 to 4.0 inch barrel length)
• Included in kit: Frame, locking block, front and rear rail modules, drill bits, and assembly jig
• Caliber support: 9mm, .40 S&W, and .357 SIG (slide and barrel not included)
• Grip angle: Standard 1911-style 18-degree grip angle for natural point of aim

One thing to note is that the PF940SC uses a standard trigger housing and trigger mechanism, which means you can drop in your preferred trigger system without modifications. The magazine release is ambidextrous and can be swapped to the opposite side for left-handed shooters. The frame also accepts standard compact magazines, which are widely available and affordable.

Who It’s For

This frame is ideal for the builder who wants a compact carry piece but prefers to assemble it themselves rather than buy a factory-complete pistol. If you have experience with basic firearm assembly and enjoy the process of customizing your own gun, the PF940SC is a solid choice. It is also a good option for someone who wants to experiment with different slide and barrel combinations without committing to a full custom build from a gunsmith. Because the frame is a blank slate, you can tailor the final pistol to your exact preferences in terms of trigger, sights, and grip modifications. That said, this is not a drop-in product; you will need to finish the frame by removing the remaining polymer tabs and drilling the pin holes using the provided jig. If you are comfortable with a drill and some hand files, you will have no trouble completing the PF940SC in an afternoon.

Shipping & FFL

Because the PF940SC is a firearm frame, it is legally considered a firearm and must be shipped to a Federal Firearms License (FFL) holder for transfer. We cannot ship this item directly to a residential address. When you place your order, you will need to provide the name and address of your chosen FFL dealer. It is your responsibility to confirm that the dealer is willing to accept the transfer and that they are properly licensed. After we receive the FFL information, we will process the shipment. Standard shipping rates apply, and delivery times vary depending on the FFL’s processing speed. Please check your local and state laws before ordering, as some jurisdictions have additional restrictions on frame purchases. We do not offer returns or refunds on PF940SC frames once they have been shipped, so make sure you understand your local regulations before completing your purchase.
