Overview

This is the blank-slate Gen3 Glock 19 path for builders planning a compact Glock-pattern pistol from a serialized aftermarket frame and matched upper parts. The profile is intentionally data-driven: generation, size, slide, barrel, rail, optic, thread, and magazine fitment all come from tags so later Glock generations can reuse the same builder without exposing a frame slot until source-backed aftermarket receiver frames exist.

Key Features

Build-planning template rather than a buyable complete firearm SKU
