Overview

The Polymer80 PF45 80% Pistol Frame Only is an unfinished, non-serialized frame that allows you to build a legally compliant, custom firearm for personal use. Machined from high-strength, impact-resistant polymer, this frame is engineered to match the ergonomics and reliability of factory large-frame pistols while giving you the freedom to select your own trigger, slide, barrel, and sights. The 80% designation means the frame is not yet a firearm under federal regulation, so no background check or FFL transfer is required for purchase. This is the exact polymer80 pf45 80% pistol frame only that serious builders trust for their personal protection or range builds.

However, it is your sole responsibility to verify that completing this frame into a functional firearm is legal in your jurisdiction. No background check is required for the purchase of this product. After completing the frame into a functional firearm, you are responsible for complying with all federal, state, and local laws regarding serialization, transfer, and possession.
