Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack

Overview

This three-pack of the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit provides the foundational components for building three complete, legally compliant, semi-automatic pistols compatible with Gen 3 Glock 19 and 23 specifications. Each kit includes an unfinished 80% frame and a dedicated jig, allowing the end user to complete the frame via machining and assembly. The PF940Cv1 platform is engineered to accept standard Glock 19/23 slide assemblies, barrels, trigger groups, and magazines, offering a modular approach to pistol construction. Each kit requires final milling of the frame rails and trigger housing pocket before assembly, and no serial number is applied by the manufacturer, as the frame is not a firearm under federal law until it is machined into a functional state.

Features and Specs

• Kit Contents per Unit: Each of the three kits includes one unfinished polymer 80% compact frame (PF940Cv1), one polymer jig with drill bushings, one set of stainless steel front and rear rail modules, one trigger housing pin, one locking block pin, one trigger pin, one slide lock spring, one slide lock, one rear rail spring, and one magazine catch assembly.
• Material and Construction: Frame is molded from high-impact, glass-reinforced polymer. Rail modules are machined from 17-4PH stainless steel, corrosion-resistant, and heat-treated for dimensional stability. Jig is precision-machined polymer with hardened steel drill bushings.
