OMG! Why would you want to do any of that crap?
'If the gun is involved in a crime' all you need to say is "what gun?" Supposedly, there is no gun registration scheme in Arizona or Federally. They like to 'trace' sometimes, but they know people buy and sell all the time. They may posture and threaten, but keeping a piece of paper with that information is more damning that it is helpful. They'll tell you the buyer was a felon (even is he/she wasn't) and all kinds of other crap. The Government is NOT your friend, and they hate you for owning a gun already. Keep it short.
It is quite extraneous to even mention this part, but.... IF, and that's a big if, you are 'questioned,' "What gun?," "Am I being detained?" "Am I free to go?" "I have nothing to say." Tell them nothing and ignore their empty threats, and believe me, there will be threats. But remember, cops love to slap cuffs on people. They wouldn't be standing there talking to you if they actually had any cause. they would kick down the door and drag you away without saying a word. They're talking to you because they're on a fishing expedition looking for any word they can twist or even pretend to hear something that sounded like a word you said that gives them any excuse at all to beat you to the ground, taze you, and drag you off. Just plain don't talk to them.
A gun being used in a crime does not incriminate you, even if there were a registry and it had your name and serial number on it. Doesn't prove whodunit. Just what, and where it used to be at some undetermined time in the past. It means next to nothing on it's own. Even if your fingerprints are all over it. Duh, it used to be your gun...
I wouldn't suggest selling to a criminal if you know it... It's just wrong. Nor does any ID need be presented, either. I probably wouldn't sell it to a toddler, no matter how much money he had....
All you need is another person with money, they hand it to you, you hand the gun to them, transaction over. Nothing illegal about it, and you have no other obligations or responsibilities; exactly as it should be.
