Frank Lawton of Deadwood, South Dakota fires his single action revolver after cocking the gun with his left hand during the Canadian Open Fast Draw Championships in Aldergrove, British Columbia July 20, 2013. The present-day Fast Draw competition was born from the Hollywood myth of the western gunfighter, and the idea is to draw a single action revolver from a holster, and cock, fire and hit a designated target in the shortest possible time. No live ammunition is ever used, only blank cartridges or wax bullets. The targets are either a metal silhouette used with wax bullets or balloons that burst from the muzzle blast from the blank cartridges. A light atop the timer signals the competitor when to fire and once the target is hit, it turns the timer off, measuring the speed to thousandths of a second. (Photo by Andy Clark/Reuters)
