Shipping & FFL

This Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit (Glock® 43 Compatible) ships directly to your residence or business address. No Federal Firearms License (FFL) transfer is required for purchase or shipment, as the frame is not classified as a firearm under federal law. However, once the frame is completed by machining the fire control cavity and installing the necessary components, the resulting product is considered a firearm and must be possessed and used in compliance with all local, state, and federal laws. It is the purchaser’s responsibility to verify that completion and possession of an 80% frame is legal within their jurisdiction. We recommend consulting with a licensed firearms attorney if you have any questions regarding compliance. We do not ship to states or localities where 80% frames are restricted or prohibited. By purchasing this kit, you acknowledge that you are solely responsible for compliance with all applicable laws and that you will not transfer the completed firearm to any person prohibited from possessing firearms.
