An 80% pistol frame’s a partially finished hand gun frame, not yet classified as a firearm. It requires additional milling and drilling to become functional. Once completed, it works with compatible pistol slides, barrels, trigger assemblies, magazines, and internal parts – commonly for Glock or 1911 style handguns. The 80% pistol frame allows DIY builders to customize and assemble their own pistols, offering flexibility for personal defense, competition, or recreational shooting builds.
