I hate the Facebook classifieds, but it does provide a really good way to judge a person by looking at their profile. There have been many times both buying and selling I could tell right away it wasn't worth the hassle. Have I dismissed good deals or buyers that were likely fine? Probably, but I don't care. I deal almost exclusively in cash, and typically will have a handgun. I try to deal with known local people as much as I can, even if it costs a little more. I have foolishly chased Craigslist deals in the past to save a few hundred bucks. I've never had any issues at all, most have been memorable adventures. Given the current state of affairs, and the fact I can afford the extra $$ for piece of mind, I don't see myself entering any risky situations any time soon. I prefer to leave the guns at home. Hey! It's only pinball!
