G19 Lower Parts Kit

G19 Lower Parts Kit Overview

The G19 Lower Parts Kit delivers all the frame internals needed to complete your compact 9mm Glock-compatible build. Every component is machined to precise specifications and tested for reliable function across the full range of Gen 3 Glock 19 platforms—from 3D printed frames like the DD19.2 to 80% builds like the G80 and Geisler Defence.

This complete LPK includes trigger assembly, slide stop, slide lock with spring, magazine catch with spring, all frame pins, and the trigger housing with ejector installed. Drop-in installation on compatible frames with no fitting required. One kit, one purchase, everything you need for the lower half of your build.

What Makes This G19 Lower Parts Kit Different

Tested Across Multiple Platforms
This isn’t a parts kit that works on paper—it’s been tested and validated across the platforms builders actually use. Compatible with 3D printed Glock 19 frames (DD19.2, FMDA variants, and remixes), the G80 steel chassis system, Geisler Defence frames, Polymer80 PF940C, and OEM Glock 19 Gen 1-3 frames. One kit covers the entire Gen 3 compact ecosystem.

Quality Components Throughout
Every part is manufactured to match OEM specifications. The trigger bar, connector, and trigger housing are machined for smooth, consistent operation. Springs are properly heat-treated for reliable tension over thousands of cycles. Pins are precision-ground for proper fit without excessive force during installation.

Ejector Pre-Installed
The trigger housing comes with the ejector already installed and properly staked. No additional parts to source, no assembly required on the housing itself. Drop it into your frame and move on to the next step.

Complete Kit – Nothing Missing
Some budget LPKs leave out components or substitute inferior springs. This kit includes everything: trigger bar with shoe, trigger housing with ejector, connector, trigger spring, slide stop lever, slide lock, slide lock spring, trigger pin, locking block pin, trigger housing pin, magazine catch, and magazine catch spring. No hunting for missing parts after the box arrives.
