1-what type of gun? (some guns have collectors groups and specialty clubs whose members would be interested)
2-what do you mean by "safest"? Not losing money, not having your personal info on the internet, or....?
3-Could you elaborate on why its important not to have the gun "in your name" anymore? This is just a curiosity question on my part....
4-you titled your post sell/trade. Are you looking for money, or will trade for another gun?
Not trying to be a pain--but its helpful to know exactly what you are dealing with in order to point you to the best options.
