There are websites that operate just like Craigslist. Dealers and private parties advertise on them. Some require a CC or purchase permit to buy, many do not. I have only bought one gun that way. I emailed the guy with my phone number. We talked for quite awhile because he is stationed at Bragg and so the conversation was about more than the gun. He told me he found out about the site and it was the first time he used it, he was a little nervous about how to handle the transfer of ownership.
I told him I would provide a photo copy of my drivers license and he would have to provide me with his receipt. If he was comfortable with that I would buy the gun. I met him at his apartment and wrote out a bill of sale on the copy of my ID. We printed our names and signed it including the serial number of the gun I kept a copy and the original receipt signed by him to me. I have decided to get my conceal and carry just to make it easier in the future. That will also allow me to have the gun loaded in my truck when I am going out to shoot. I highly doubt I will ever carry one on me. I have never purchased one at a gun show~
