What does “Compact Long Slide” (CL) mean?
The “CL” designation is the core innovation of this frame. It features the shorter, more concealable grip frame of a Glock 19, allowing for a comfortable and discreet hold, while the front rail section and slide rails are extended to accommodate the longer slide and barrel of a Glock 17 or 34. This hybrid design gives you the ballistic and sight radius advantages of a full-size slide on a more manageable frame.
What parts do I need to complete this 80% frame?
To finish this frame into a functional firearm, you will need a Polymer80 single-stack frame jig and the appropriate drill bits (sold separately), a compatible Gen 3 slide parts kit, a lower parts kit (LPK), a magazine, and your chosen Gen 3 Glock 17/19/34 slide assembly complete with barrel and recoil spring. Always ensure compliance with all federal, state, and local laws regarding firearm manufacturing.
Is this frame compatible with aftermarket Glock accessories?
Yes. The PF940CL is designed to the widely supported Gen 3 Glock specification. It will accept the vast majority of aftermarket triggers, connectors, pins, and other lower parts kits made for Gen 3 models. Its rail system is compatible with many standard Glock holsters designed for the hybrid profile, though we recommend checking fit with your specific holster.
What magazines does the PF940CL frame use?
Thanks to its compact grip dimension, this frame seamlessly accepts standard 15-round Glock 19 magazines, 17-round Glock 17 magazines, and 19-round Glock 19X magazines. The magazine well provides a clean, flared entry for reliable reloading, making it an excellent choice for both everyday carry and range use where magazine commonality is a benefit.
