Your Questions Answered
What tools do I need to complete this 80% frame?
You’ll need a hand drill or drill press, a hobby vise, and some basic hand tools like files and sandpaper. The included jig guides your drill bits for the trigger and pin holes. The polymer is easy to work with using standard metalworking tools.
Will this work with a Glock 26 slide and parts kit?
Yes. The PF940SC is designed specifically for the Glock 26/27 platform. It will accept standard Gen 3 Glock 26 slides, barrels, recoil spring assemblies, and lower parts kits (LPK). Everything drops right in once the frame is properly completed.
Is the rear rail module pre-installed?
No. The rear rail module, front locking block, and all pins are included in the kit but require installation. The jig provides precise alignment for installing the rear rail module, which is a critical step for ensuring proper slide-to-frame fit and function.
