Key Features
The Polymer80 PF940SC Jig Kit is meticulously engineered for accuracy and ease of use. Its robust polymer construction provides a stable and vibration-dampening platform during the milling process, ensuring clean and precise cuts. The jig’s design incorporates strategically placed locating pins and guides, simplifying the process and minimizing the risk of errors. We’ve focused on creating a jig that’s both durable and user-friendly, even for those new to 80% builds. The included steel bits are specifically hardened and ground to withstand the demands of cutting polymer, guaranteeing longevity and consistent performance. This isn’t just a jig; it’s a precision tool designed to elevate your Polymer80 building experience, offering a level of accuracy and repeatability that’s hard to find elsewhere. The compact design also makes it easy to store and transport, allowing you to take your build project on the go.
This jig is specifically designed for the Polymer80 PF940SC frame, which is a popular choice for those seeking a compact and concealable pistol. The PF940SC frame is compatible with Glock 26 magazines and utilizes a similar small-frame design. It’s important to note that this jig is *only* compatible with the PF940SC model; it will not work with other Polymer80 frames or 80% lowers. The PF940SC frame is typically chambered in 9mm, making it a versatile option for personal defense and recreational shooting. The jig’s precision ensures that the finished frame will accept standard Glock 26 slide assemblies and internal components, allowing for a wide range of customization options. Proper fit and alignment are critical for a functional firearm, and this jig is engineered to deliver just that, providing a solid foundation for your build.
Materials
We prioritize quality and durability in every component of the PF940SC Jig Kit. The jig body itself is constructed from a high-impact polymer, chosen for its strength, resistance to wear, and ability to dampen vibrations during the milling process. This polymer is specifically selected for its dimensional stability, ensuring consistent performance over time. The included drill bits and end mill are crafted from high-speed steel (HSS), a material renowned for its hardness and ability to maintain a sharp cutting edge even under heavy use. These steel bits are heat-treated for added durability and are precisely ground to the correct specifications for accurate polymer removal. The pins are also made from hardened steel, providing secure and reliable locating points. Our manufacturing standards adhere to strict quality control measures, ensuring that each kit meets our rigorous performance criteria. The finish is a durable black coating, providing both aesthetic appeal and protection against corrosion.

How It Works
Building a Polymer80 PF940SC with this jig kit is a straightforward process, though it requires patience and attention to detail. First, securely clamp the 80% Polymer80 PF940SC receiver into the jig, ensuring proper alignment with the locating pins. The jig’s design guides you through the milling process, indicating precisely where and how much material needs to be removed. Using a drill press (recommended for accuracy and safety), begin by drilling the initial pilot holes using the provided drill bits. Follow the jig’s markings and the included instructions to progressively remove material with the end mill. It’s crucial to take shallow cuts and frequently check your progress to avoid over-milling. A rotary tool (like a Dremel) can also be used, but requires a more steady hand and careful control. After completing the milling process, remove the receiver from the jig and perform any necessary deburring and finishing work. Finally, install your chosen internal components (trigger, hammer, etc.) and slide assembly to complete your custom PF940SC pistol. Remember to always prioritize safety and follow all applicable laws and regulations.
Frequently Asked Questions
Is this subcompact jig kit legal to purchase in the United States?
The Polymer80 PF940SC Jig Kit itself is generally legal to purchase in the United States. Federal law currently classifies an 80% lower receiver as a part, not a firearm, prior to completion. However, it’s *crucially important* to understand that state and local laws vary significantly. Some states have enacted legislation restricting or prohibiting the manufacture of firearms, including 80% lowers. It is your responsibility to research and comply with all applicable laws in your jurisdiction before purchasing or building this kit. We strongly advise consulting with a legal professional to ensure compliance.
Does buying this subcompact jig kit require an FFL dealer?
No, at the federal level, purchasing this jig kit does not require an FFL (Federal Firearms License) dealer. The kit ships directly to you, as it is considered a firearm part. However, depending on your state’s laws, you may be required to register the completed firearm or undergo a background check. It’s essential to verify your state’s specific requirements regarding the assembly and ownership of firearms. We do not provide legal advice and cannot be held responsible for your compliance with local regulations.
What other parts do I need to complete a build using this subcompact jig kit?
The Polymer80 PF940SC Jig Kit provides the tooling to complete the frame, but you’ll need several other components to build a fully functional pistol. These include a slide assembly (compatible with Glock 26 slides), a barrel, a recoil spring assembly, a trigger, a hammer, a fire control pin set, a magazine release, a takedown pin, and a magazine. You will also need appropriate fasteners and small parts. Sourcing these components from reputable vendors is essential to ensure the safety and reliability of your finished firearm. A complete parts list can be found on numerous online forums and resources dedicated to Polymer80 builds.
How difficult is a Polymer80 build for a beginner?
A Polymer80 build can be a rewarding project, but it’s not without its challenges. It requires a certain level of mechanical aptitude, patience, and attention to detail. While the jig simplifies the milling process, you’ll need access to a drill press or rotary tool and a basic understanding of their operation. The learning curve can be steep for complete beginners, but numerous online tutorials and resources are available to guide you through the process. Allow ample time for the build, and don’t rush any steps. Safety should always be your top priority.
Will standard factory Glock Gen3 parts work in Polymer80 frames?
Yes, generally, standard factory Glock Gen3 parts are compatible with Polymer80 PF940SC frames. The frames are designed to accept the same internal components and slide assemblies as the original Glock 26. However, there can be slight differences between Gen3 and Gen4 Glock parts, and some Gen4 components may not fit perfectly. Aftermarket parts are also readily available, offering a wider range of customization options and improved performance. It’s always a good idea to double-check compatibility before purchasing any parts.
