The PF940C frame’s design mirrors the Glock 19 Gen 3 geometry, ensuring reliable function with a vast aftermarket. The fiberglass-reinforced polymer matrix provides impact resistance and dimensional stability critical for a secure rail and locking block fit. This 3-pack is ideal for builders stocking up for multiple 9mm, .40 S&W, or .357 SIG builds. Completion of an 80% frame requires tools and creates a firearm; builders must comply with all federal, state, and local laws.
