Glock 19 Frame: The Complete DIY Kit (No FFL) – Build Your Own Polymer80

Building your own Glock 19 frame might sound daunting, but with the right kit and a little patience, it's entirely achievable. This guide provides a comprehensive overview of what's involved in constructing a Polymer80 Glock 19 frame, emphasizing the legality and safety aspects crucial for this project. Remember, always adhere to your local and state laws regarding firearm construction and ownership.

Understanding the Polymer80 Kit

Polymer80 is a popular choice for DIY Glock frame kits because they offer a complete package, eliminating the need to source individual components. A typical kit includes:

• The 80% Polymer Frame: This is the unfinished lower receiver. It requires significant machining to become a functional firearm frame.
• Jigs and Tools: Polymer80 kits usually include the necessary jigs and tools to aid in the milling and finishing process. This simplifies the process and improves accuracy.
• Instructions: Detailed instructions are provided, guiding you through each step of the build. Carefully follow these instructions for best results.

What You'll Need Beyond the Kit

While the Polymer80 kit provides many necessary components, you'll still need a few additional tools and supplies:

• Drill Press: A drill press is essential for precise drilling of the various holes required. A hand drill is highly discouraged due to the risk of inaccuracy.
• End Mills: These are used for the milling process, shaping the frame to accept the various internal components.
• Files and Sandpaper: Used for smoothing and finishing the frame after milling.
• Appropriate Safety Gear: Eye protection, ear protection, and gloves are absolutely mandatory throughout the entire process.

The Build Process: A Step-by-Step Overview

The exact steps will vary slightly depending on the specific Polymer80 kit you purchase, but the general process involves:

1. Preparation: Carefully read the included instructions. Gather all your tools and supplies. Ensure you have a clean and well-lit workspace.
2. Jigs and Clamping: Securely attach the necessary jigs to the frame according to the instructions. This ensures accurate drilling and milling.
3. Drilling: Use the drill press to carefully drill the holes outlined in the instructions. Accuracy is paramount here.
4. Milling: Use the end mills to carefully mill the various channels and surfaces needed for the internal components.
5. Deburring and Finishing: Remove any burrs or sharp edges using files and sandpaper. Ensure a smooth finish to prevent any potential issues with the internal components.
6. Assembly: Once the frame is finished, you can assemble the internal components (slide, barrel, etc.) to create a functional firearm. Remember, you will need to source these separately.

Legal Considerations: Navigating the 80% Lower Landscape

The legality of building a firearm from an 80% lower receiver varies significantly by state and local jurisdiction. It is your responsibility to understand and comply with all applicable laws. Some jurisdictions have outright bans, while others have stricter regulations regarding registration or background checks. Research your local laws thoroughly before beginning this project.

Safety First: A Critical Reminder

Working with tools and firearm parts is inherently risky. Always prioritize safety:

• Wear appropriate safety gear.
• Work in a well-ventilated area.
• Never point the firearm at anything you don't intend to shoot.
• Handle all tools and firearm parts with care.

Building a Glock 19 frame from a Polymer80 kit is a challenging project, but rewarding for those who possess the necessary skills and tools. By carefully following instructions and prioritizing safety and legality, you can successfully create a functional firearm. However, always remember that owning and operating a firearm comes with significant responsibilities. Ensure you are properly trained and familiar with firearm safety protocols before handling your completed build.
