Overview

The Polymer80 PF940SC kit is engineered for subcompact platforms, offering a compact grip length and slide profile compatible with Gen3-style Glock 26 and 27 parts. The frame is constructed from reinforced polymer, matching the durability of factory frames while providing an ergonomic texture and undercut trigger guard.

This is a complete starting point for building a concealed carry pistol or a range-specific firearm without requiring a serialized receiver purchase.

Who It’s For

This kit is intended for individuals legally permitted to own firearms who wish to complete a frame at home.
