Welcome back! Hope you are doing well- have had a couple of friends go thru that and it is a bear.
Ref: selling- you do not need to be a FFL to sell a gun, unless you are doing it for a living. You can sell TO a FFL in any state (except handguns cannot go to a FFL in NY State except FROM a FFL) You can sell to a resdient of your own state without it going to a FFL, but NC DOES require a handgun purchase permit even for private sales- see your County Sheriff for some more info.
You can post them in the classified section here. You can also put them up at Gunbroker or Auction Arms. Unless you ARE a FFL, cost of shipping a handgun will make you weep ($70-$75) You may also find a good dealer there in NC that will sell them on consignment for you.
What we have here is... failure- to communicate.
