not all states allow private face to face sales. california comes to mine were I still have a few fire arms at my parents house.There is no requirement to document a private party sale within a state,registerd, transfered, logged to what ever name you want to give it. all modern new fire arms that were made by a manufature have to be transfered and while the terms the goverment uses may vary the fact is if you by it and transfer it to your name they know who has it. registerd or transfered there is liitel diffrance other than the name. you are correct fire arms are transferd to individule not registerd. what the differance is technicaly is likely very little. its all traceable paper work putting it in your name. when I sell a fire arm I perfer to have them tansfered into the new owners name and more importantly out of mine. I dont need some gun I sold 20 years ago showing up at a crime scene. guns I by face to face I always check if there stolen CYA .Let's remember for a moment that despite being "traceable" there is no "registration" of rifles and shotguns in this country. Rifles and shotguns are NOT registered (in most cases) to people but transferred either through FFL's or via private sale which the government has no business documenting at this time.
