On tonight's Curator's Corner, John Popp joins National Firearms Museum Senior Curator Phil Schreier and competitive shooter Jon Michael McGrath for a special segment at the Wanenmacher's Tulsa Arms Show in Tulsa, Oklahoma. A Tulsa native, McGrath describes his experiences learning to shoot in the Boy Scouts and competing around the world. He presents his Krieghoff 80 competition shotgun for display, pointing out the various custom features. McGrath, who hopes to qualify for the Olympics, has this gun virtually rebuilt four times a year due to the extensive use that it sees. Originally aired 6/24/2010.
