3D Printed G19 Build Kit

3D Printed G19 Build Kit Overview

The 3D Printed G19 Build Kit includes everything you need to complete your DD19.2 frame. Instead of sourcing parts from multiple vendors and crossing your fingers on compatibility, this kit bundles a complete slide assembly, precision rails, locking block, and full lower parts kit in one purchase.

We built this kit specifically for the FMDA DD19.2 3D printed Glock 19 frame. Print your frame, open the box, and get to work. Every component is matched and tested, so you’re building instead of troubleshooting.

What’s Included in This 3D Printed Glock 19 Kit

Complete G19 Slide Assembly
Black nitride slide machined from 416 stainless steel and heat treated to 42 HRC. Includes an Optimus Series flush cut barrel with polygonal rifling and 1:10 twist, complete upper parts kit, and polymer sights with a white dot front. H&M Precision handles the nitride finish for solid corrosion resistance and durability.

DD19.2 Rail & Locking Block Kit
Precision-formed stainless steel rails built for the DDxx.2 mounting system. The front rails are the same proven FMDA G19 design used in thousands of successful builds. Rear rails feature the improved no-screw system that makes DD19.2 frames stronger and easier to assemble than older designs.

17-4 Stainless Steel Locking Block
CNC machined to exact specifications. 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 remixes.

G19 Lower Parts Kit
Everything for the frame internals: trigger bar, trigger housing with 9mm ejector already installed, 5.5lb connector, all springs, slide stop, slide lock, three frame pins, and magazine catch. Drops right into a properly printed frame without fitting.

Why Builders Choose This 3D Printed Glock Kit

One Kit, Zero Compatibility Issues
We selected every component to work together out of the box. The slide uses Gen 3 internals that match the lower parts kit. The rails fit the DD19.2 mounting system. You won’t spend hours on forums figuring out what works with what.

100% American Made
The slide and barrel are machined from domestic stainless steel and finished by H&M Precision. Rails and locking block come from Wisconsin. This is a domestic-built parts kit, not a pile of overseas castoffs.

Save Money and Time
Bundle pricing beats buying components separately. One shipment instead of four, and you’re not stuck waiting on back-ordered parts from different suppliers while your printed frame sits around.

The Most Popular 3D Printed Glock Design
The DD19.2 is the go-to choice for compact 3D printed pistol builds. Thousands of successful builds, solid documentation, and a helpful community when you need it. This kit gives you the parts. The design gives you confidence.

What Else You Need for Your 3D Printed G19

DD19.2 Frame (You Print This)
Files are available on DEFCAD. Search for “DD19.2” or “FMDA Glock 19” and you’ll find them quickly. The download includes print settings, assembly instructions, and video walkthroughs. PLA+ works well for most builders. Glass-filled Zytel makes stronger frames if you have experience with engineering filaments.

Magazine
Any Glock 19 magazine from Gen 3 through Gen 5 will work, along with the Magpul PMAG 15 GL9. G17 magazines fit too if you want extra capacity, they’ll just extend below the grip. We sell magazines separately.

Basic Tools
A punch set, hammer, and sight pusher will handle the build. Standard tools you probably already own.
