DD19.2 Rail & Locking Block Kit

DD19.2 Rail & Locking Block Kit Overview

The DD19.2 Rail and Locking Block Kit provides the essential metal components needed to complete your FMDA DD19.2 3D printed Glock 19 frame. This bundle includes precision-formed front and rear rails plus a 17-4 stainless steel locking block—everything required to transform your printed frame into a functional compact 9mm pistol.

The FMDA DD19.2 is one of the most popular 3D printed Glock 19 frame designs available, known for its trouble-free assembly and improved rear rail system that eliminates the screws found in earlier FMDA designs. This kit is manufactured in the USA from high-quality stainless steel and machined to tight tolerances for reliable fit and function.

What Makes This DD19.2 Kit Different

Precision-Formed Rails
The front rails in this kit are the same high-quality, high-tolerance rails offered in the original FMDA G19 rail kit—proven components with thousands of successful builds. The rear rails feature an all-new design specific to the DDxx.2 frame series, engineered to work with the improved no-screw mounting system that makes the DD19.2 stronger and easier to assemble than previous generations.

Frame-Supported Rear Rail Design
Unlike earlier FMDA designs that relied solely on screws, the DD19.2’s rear rails are supported by both the frame and the trigger components. This dual-support system creates a more rigid, reliable platform. To protect these precision-formed rails during shipping, we include a protective holder that maintains proper dimensions until installation.

Matched Locking Block
The included Gen 3 compact locking block is machined from 17-4 stainless steel for strength and corrosion resistance. This is a direct replacement for Glock Part #7894 and fits all three-pin Gen 3 Glock 19 pattern builds, including the DD19.2 and its various remixes.

American Manufacturing
Every component in this kit is 100% made in the US. The rails are precision-formed from high-quality stainless steel, and the locking block is CNC machined to exact specifications. No overseas sourcing, no quality compromises.
