Duel for the weapon you want to dupe.
Whoever owns the gun is the one who has to die.
Start the duel but before you kill them have them drop said gun.
The person the dies picks up their copy and you receive a duplicate of the exact same thing for winning the duel.
It's easier to drop all your items right at a save point and turn off console or app. Then rejoin and your items are back.
