The Polymer80 PF940C is an 80% compact frame kit, ideal for firearm enthusiasts and builders seeking to create a customized Glock 19 style pistol. This kit provides the core component for a personalized build, offering a cost-effective and rewarding path to owning a unique firearm. It’s perfect for those who want control over every aspect of their pistol’s construction.
Key Features
The Polymer80 PF940C isn’t just another 80% frame; it represents a commitment to accessible firearm building. Designed with the home builder in mind, the PF940C prioritizes ease of completion without sacrificing durability or reliability. Polymer80 frames are known for their simplified build process, requiring minimal specialized tools and expertise. The design focuses on reducing the amount of machining required to complete the frame, making it a popular choice for first-time builders. The PF940C’s compact size makes it a versatile option for concealed carry and general use, mirroring the popular Glock 19 platform. Builders choose Polymer80 for the freedom to create a firearm tailored to their specific needs and preferences, bypassing some of the restrictions associated with traditional firearm purchases.
This pf940c compact frame is specifically engineered for compatibility with Glock 19 Gen3 (9mm) and Glock 23 Gen3 (.40 S&W) components. It’s crucial to understand that this is an 80% frame, meaning it requires further machining to be legally considered a firearm. The PF940C is designed to accept standard Glock Gen3 internals, including the slide, barrel, trigger, and magazine. The frame’s dimensions closely match those of a factory Glock 19, ensuring a seamless fit with existing Glock parts. The receiver well is precisely molded to accommodate Glock magazines, and the trigger guard is sized for comfortable and safe operation. When completing the frame, builders must ensure accurate drilling and milling to maintain proper function and safety. The kit includes a jig designed to aid in this process, but precision and attention to detail are paramount.
The Polymer80 PF940C is constructed from a reinforced polymer, chosen for its strength, lightweight properties, and resistance to corrosion. This material provides a solid foundation for your build, capable of withstanding the stresses of regular use. The frame’s surface has a textured finish, providing a secure grip and enhancing control. During the build process, the polymer is relatively easy to work with, allowing for clean and precise machining. Once completed, the frame exhibits good dimensional stability and maintains its shape under varying environmental conditions. The polymer material also helps to dampen recoil, contributing to a more comfortable shooting experience. The finish is durable enough to withstand handling and wear, but can also be customized with paint or other coatings to personalize your firearm.

How It Works
The Polymer80 PF940C serves as the foundational component in building a customized pistol. Unlike a fully assembled firearm, this kit provides an unfinished polymer frame that requires completion through drilling and milling operations. The included jig is a critical tool, guiding the builder in accurately positioning drill bits and the end mill to create the necessary cavities and features within the frame. The process begins by securing the frame within the jig. Then, using the provided drill bits, the builder carefully drills through designated points on the frame, creating holes for the trigger pin, takedown pin, and other internal components. Following the drilling process, the end mill is used to precisely shape the receiver well, ensuring proper magazine compatibility and smooth operation. Throughout the build, it’s essential to follow the instructions carefully and prioritize accuracy. Once the machining is complete, the builder can assemble the frame with standard Glock Gen3 parts – slide, barrel, trigger assembly, and magazine – to create a fully functional pistol. The result is a firearm that is uniquely yours, built to your specifications and preferences.
Frequently Asked Questions
Is it legal to buy a polymer80 frames in the United States?
The legality of purchasing and possessing 80% frames is a complex issue that varies significantly by location. At the federal level, 80% frames are generally considered legal to purchase as they are not classified as firearms until fully assembled. However, the ATF has recently issued rulings that may change this classification, and it’s crucial to stay updated on current regulations. Many states have enacted laws specifically regulating or prohibiting 80% frames and the parts necessary to complete them. These laws can range from requiring serial numbers to outright bans. It is the buyer’s responsibility to understand and comply with all applicable federal, state, and local laws before purchasing a Polymer80 frame.
Do I need an FFL dealer to purchase this polymer80 frames?
Generally, no, you do not need a Federal Firearms License (FFL) dealer to purchase an 80% frame like the Polymer80 PF940C at the federal level. This is because the frame is considered an unfinished component and not a regulated firearm until it is fully assembled and functional. However, some states may require a background check or other forms of verification even for the purchase of unfinished frames. Always verify your local and state laws to ensure compliance. Purchasing from a reputable dealer like p80source.com helps ensure you receive a legitimate product and can access helpful information regarding legal requirements.
What tools do I need to complete a build with this polymer80 frames?
Beyond the tools included in the kit (jig, drill bits, end mill), you’ll need a few essential tools to complete a Polymer80 build. A drill press is highly recommended for accurate and consistent drilling. A set of quality drill bits, beyond those provided, can be useful for deburring and finishing. A vise is essential for securely holding the frame during machining. Safety glasses and a dust mask are crucial for protecting your eyes and lungs. A file or sandpaper can be used for smoothing edges and refining the finish. A hammer and punches may be needed for installing pins. Finally, a good set of screwdrivers and other hand tools will be necessary for assembling the completed frame with Glock components.
How long does it take to complete a Polymer80 polymer80 frames build?
The time it takes to complete a Polymer80 build varies depending on experience and available tools. A first-time builder can expect to spend anywhere from 4 to 8 hours completing the frame, including careful drilling, milling, and deburring. Experienced builders who are familiar with the process and have the right tools can often complete a frame in 2 to 4 hours. It’s important not to rush the process, as accuracy and attention to detail are critical for ensuring a safe and functional firearm. Allow ample time for each step and double-check your work to avoid errors.
Will standard Glock components fit in Polymer80 frames?
Yes, standard Glock Gen3 components are designed to fit seamlessly into Polymer80 frames like the PF940C. The frames are specifically engineered to accept Glock slides, barrels, triggers, magazines, and other internal parts. However, it’s important to note that some aftermarket Glock components may require slight modifications or adjustments to fit properly. The Polymer80 frames generally work best with genuine Glock parts or high-quality aftermarket components that are specifically designed for Glock compatibility. Always verify compatibility before purchasing aftermarket parts and be prepared to make minor adjustments if necessary.
