Polymer80 PF940CV1 80% Pistol Frame Kit

The PF940CV1 is an 80%-style pistol frame for Glock Gen 3 compatible builds, cut for compact double-stack slides like the G19. This unfinished frame weighs 5.8oz in reinforced polymer with an aggressive undercut trigger guard and Picatinny accessory rail. The kit includes the frame blank, drilling jig, and 3mm/4mm drill bits — you’ll need a slide assembly, barrel, and LPK to complete.

Designed for builders who prefer hands-on fitment, the PF940CV1 has relief cuts for aftermarket trigger housings and a stippled grip texture that won’t chew up your hands. The rear rail module accepts standard Gen 3 components, and the locking block is pre-installed. Currently legal in most states as an unfinished receiver — verify your local and state laws before ordering.

This P80-pattern frame ships with minimal machining marks and enough material left for custom grip reduction. The PF940CV1 works with OEM or aftermarket Glock 19 slides, though tighter tolerances may require light filing on the front rail contact points. Includes lifetime warranty against manufacturing defects.
