Pawn Stars season 15 episode 20

Episode title: Fully Vested

The Pawn Stars start off with a bang when a beautiful pair of 18th century breech-loading pistols breach the shop. Will these guns hit the bullseye or will they misfire? Things get heavy when a seller brings in a paperweight made by renowned glass artist Paul Stankard. A vest made to hold the 14 harmonicas of Blues Traveler frontman John Popper is music to Chum's ears; Popper himself even pops into the shop to give Chum a harmonica lesson.
