How It Works
Building with the Polymer80 PF940C Buy Build Shoot Compact Kit is a rewarding experience. First, you’ll use the included jig and drill bits to complete the 80% frame, carefully following the instructions.

Once the frame is complete, you’ll install the included Lower Parts Kit (LPK), which contains the trigger, hammer, safety, and other essential parts. Next, you’ll attach the slide to the frame and insert the 4-inch barrel. Finally, you’ll perform a function check to ensure all components are working correctly. Essential tools for this build include a drill press, a set of drill bits, punches, and screwdrivers. The end result is a fully functional 9mm pistol, customized to your specifications. Remember to always prioritize safety and follow all applicable laws and regulations.
Frequently Asked Questions
Is this complete compact build kit legal to purchase in the United States?
At the federal level, an 80% receiver is not classified as a firearm and generally does not require a background check or serial number. However, state and local laws vary significantly. It is your responsibility to understand and comply with all applicable laws in your jurisdiction before purchasing and building a firearm. Some states may have restrictions on 80% receivers or require serialization. Always consult with a legal professional if you have any questions regarding the legality of this kit in your area.
Does buying this complete compact build kit require an FFL dealer?
No, purchasing this 80 percent compact kit generally does not require an FFL dealer at the federal level because it is sold as an unfinished receiver. The kit ships directly to your door. However, some states may require all firearm-related purchases to go through an FFL, even for 80% receivers. It is crucial to verify your local regulations before ordering. We are not responsible for ensuring compliance with state-specific FFL requirements.
What other parts do I need to complete a build using this complete compact build kit?
While this kit includes the core components, you will need to source a few additional parts to have a fully functional pistol. These include magazines, a recoil spring assembly (if not included in your LPK variation), and potentially a magazine release button. You may also want to consider purchasing additional grip screws, slide stop pins, and other small parts for a more secure and reliable build. A quality cleaning kit is also recommended for maintaining your finished firearm.
How difficult is a Polymer80 build for a beginner?
A Polymer80 build is generally considered to be relatively straightforward, even for beginners. However, it does require some mechanical aptitude and attention to detail. You’ll need basic tools like a drill press, drill bits, and punches. The process takes approximately 2-4 hours to complete, depending on your experience level. There are numerous online resources, including videos and forums, that can provide guidance and support. Patience and careful adherence to the instructions are key to a successful build.
Will standard factory Glock Gen3 parts work in Polymer80 frames?
Yes, Polymer80 frames are designed to be highly compatible with standard factory Glock Gen3 parts. This allows you to use genuine Glock components for your build, ensuring reliability and performance. While compatibility with Gen4 parts is limited, a wide range of aftermarket Glock parts are available that will work seamlessly with Polymer80 frames. This provides builders with a great deal of flexibility in customizing their firearms. You can easily upgrade components like triggers, sights, and grips to enhance your shooting experience.
