POLYMER80 PF940C

Polymer80 (P80) is a manufacturer specializing in Glock-compatible firearm frames and parts, originally known for their "80% receivers" that allowed hobbyists to build firearms at home without a serial number. However, as of March 2026, the company has faced significant legal and operational changes. Following a series of lawsuits and a 2024 liquidation process, the original Polymer80 entity reportedly ceased operations, though its products remain available through various third-party retailers
