The Pawn Stars fire off to the shooting range to check out an antique signal cannon from the 1980's TV series Magnum P.I. Then, the guys feel the heat when a lighter and photos from a top-secret 1950's atomic bomb testing program come into the shop. And later, a guy beams by the shop with a carload of is signed Star Trek memorabilia.
