As other posters mentioned, I sometimes refer to my guns as weapons-because they are.

Not too long ago I sold a 22 mag by posting a sign at my range. The guy who bought it from me had prepared "receipts." We printed and signed our names, the date of course, weapon (ahem) type and serial number. The guy also had a friend there as a witness who also signed.

I appreciated the guys thoughtfullness.

If you do decide to sell, I would recommend doing something similar. You don't necessarily have to have the thing notarized, just enough toshow that a transfer did occur.

But like other posters have said: it is your gun. If you are uncomfortable selling it to this person, then don't.
