I just bought a Keltec PF9 for conceal carry. As I took it apart to familiarize myself with the gun I noticed a barrel defect on the outside and inside of the barrel. I want to go about sending the gun in for warranty, which leads us to my question. Do I have to go through an FFL to send and receive my gun for warranty service? Or Can I send it from my local FedEx and receive the gun at home? Also I'd like opinions on whether this defect is a big deal or not and whether I should call them or just send the gun in.
