I'm planning to go to the Gun & Knife show in Novi this weekend, to look for something to carry when I get my CPL. Even if I don't buy anything, it'll be nice to be able to compare guns in person rather than from a few pictures and a specification list. ... But, if I do want to buy something, what should I be looking for to determine the condition of a gun? Obviously finish wear, but I'm more concerned with the condition of the rifling and working parts. Are dealers usually pretty honest when it comes to reporting condition?
