The PF940CL comes with everything necessary to complete a Gen 3 Glock 17/22 compatible pistol frame. The frame is also optionally compatible with G17 Gen4 slides after a simple modification to its dust cover. It's available with our aggressive standard grip texture or ReadyMod blank grip for custom stippling and modification. The kit comes with a blank serialization plate and complete finishing jig, drill bits and end mill. Compatible with Glock 17/22 Gen3 Slide Assemblies and Glock19/23 magazines.
