Frequently Asked Questions
What tools do I need to complete this frame?
You will need a handheld drill or drill press, a vise, and a hammer. The included jig provides precise guides for the milling and drilling operations. A Dremel tool or router can be used for the milling step, but careful hand filing is also an option.
Is this compatible with aftermarket slides and parts?
Yes. The PF940SC™ frame is designed to work with OEM Glock® 26/27 parts and the vast majority of aftermarket slides, barrels, and internal components made to Gen 3 specifications. We recommend verifying compatibility with your specific parts list.
