Overview

The Polymer80 PF940C 80% Pistol Frame Only is a compact, unfinished frame that requires light machining to complete. It is made from high-strength, impact-resistant polymer and includes a stainless steel front rail system and rear rail module. This frame is designed to accept standard Glock 19 Gen 3 internal parts, including the trigger assembly, locking block, and slide components. Because it is an 80% frame, it is not considered a firearm by federal regulation until machining is complete, giving you a legal path to build a pistol that is uniquely yours. The Polymer80 PF940C 80% Pistol Frame Only is widely used for concealed carry builds, range pistols, and personal defense projects.
