Frequently Asked Questions
What parts do I need to complete this frame?
You will need a PF45-specific jig and drill bits, a lower parts kit (LPK), a slide completion kit, and a slide/barrel assembly. The jig and tools are sold separately.
Is this compatible with Glock® parts?
The PF45 is designed to be compatible with aftermarket large-frame Glock®-pattern parts for models in 10mm and .45 ACP. Always verify part compatibility with your specific build.
What is the condition when it arrives?
The frame itself is precisely molded and high quality. Please note, as our staff has observed, the product packaging is a simple, flimsy box, so the item may arrive with minimal retail packaging.
