Polymer 80 Glock 19 Complete Build Kit

This Polymer 80 Glock 19 complete build kit ships with everything needed to finish your 80%-style frame except the slide assembly. Built on the P80-G19 platform (Gen3 compatible), the reinforced polymer frame weighs 8.3oz with aggressive texturing and a relieved trigger guard for high-hand grips. Includes frame, jig, drill bits, and rear rail module — you supply the slide, barrel, and internal parts kit.

The frame’s Picatinny accessory rail accepts standard G19 lights, and the undercut below the trigger guard reduces bulk for competition-ready draw strokes. Milled for Gen3 Glock 19 slides, this 80% build maintains the OEM 4.02″ barrel length and accepts aftermarket triggers. Currently legal in most states as an unfinished receiver — verify your local and state laws before ordering.

For builders who want a complete Polymer 80 Glock 19 project without hunting down components separately. The jig’s carbide drill guides ensure clean takedown pin holes, and the frame’s reinforced locking block area handles +P loads. Ships with serialization plate for states requiring home-built firearm registration.
