19X V3

19X V3 Features

The 19X V3 stands out with its iterative improvements over previous FMDA Glock frames, focusing on durability and ease of use. This design eliminates the weak screw-in rear rails, incorporating dimensional tweaks for smoother assembly and a more secure fit.

Key highlights include:

• Enhanced Frame Stability: Refined structure to address past weak points, ensuring a long-lasting build.
• Upper Compatibility: Fully compatible with G23 uppers, expanding your customization options.
• Community-Driven Design: Built on over a year of user feedback for optimal performance.

This frame leverages the availability of high-quality commercial rails, meaning you no longer need to craft rails from scratch. It’s a practical solution for both seasoned builders and those looking to streamline their DIY firearm projects.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days (including printing and assembly)
• Required Experience: Familiarity with 3D printing, basic firearm assembly, and access to compatible hardware or rails.

Hardware and Tools Required

Required Hardware

• Glock 19 or G23 upper components (slide, barrel, etc.)
• Commercial rails (available from vendors like Avesrails.com or Riptiderails.com)
• Compatible springs (note: G5Spring version uses Glock Gen5 style spring setup)
• Standard Glock frame pins and small hardware for assembly

Recommended Tools

• 3D printer with a 0.4mm nozzle
• Screwdrivers or pin punches for assembly
• Sandpaper or finishing tools for post-print cleanup
• Calipers for precise measurements during assembly

19X V3 Parts

The 19X V3 file includes the STL data for printing a refined Glock 19 frame, inspired by the FMDA DD19.2 design. For best results, use a 0.4mm nozzle as larger nozzles may cause holes in the print. Recommended materials include durable options like PETG or ABS to withstand the rigors of firearm use.

Special printing considerations include:

• Layer Height: 0.16mm for detailed resolution.
• Infill: 100% for maximum strength.
• Walls: 8 for structural integrity.
• Supports: Use tree supports with a close interface gap (not larger than 0.16mm) and set Support X/Y Distance to 1.3mm in Cura to avoid supporting stipples.

For Prusa Slicer users, ensure Detect Thin Walls is turned off. Detailed build instructions are available in the accompanying PDF guide at the provided link for seamless assembly.

Printer Compatibility & Settings

The 19X V3 is compatible with most FDM 3D printers capable of handling a 0.4mm nozzle and precise layer heights. Recommended materials are PETG or ABS due to their strength and heat resistance, ideal for firearm frames. Avoid PLA as it may not withstand the mechanical stress of this application.

Key print settings include:

• Nozzle Temperature: 215-230°C
• Bed Temperature: 60°C
• Cooling: As low as possible for your printer setup
• Supports: Full, with tree supports preferred for material efficiency

Ensure your printer is calibrated for tight tolerances, as this design demands precision. If slice times are too long with tree supports, switch to normal supports, though this may use more material. All other settings can remain default or adjusted based on your printer’s known performance.

Conclusion

The 19X V3 is a game-changer for 3D printing and firearm enthusiasts, offering a refined Glock 19 frame that balances innovation with practicality. With its community-driven updates and compatibility with commercial rails, it simplifies the DIY process while ensuring a robust build.
