Other mistake: In the beginning when Yuri sells his first gun, an Uzi, in the hotel room, he states "It shoots hollow points." Yet all the ammo in the case are full metal copper jackets.
Suggested correction: It's the first time he tries to sell a gun. He is just wrong about the bullet type. Common mistake to make for a rookie.
Continuity mistake: After changing the name of the freighter from Kristol to Kono, there is a moment where you see Valentine's perspective as he examines the name on the stern of the ship. For some reason in this shot, the K in Kono is inverted.
Suggested correction: Except it isn't. K is the correct orientation during this shot.
