Ruger Range Drills Season 2 - One Shot Drill From Holster. This drill combines the Drawing from a Holster and One Shot drills. Once it’s been practiced for mechanics and the movement is correct, move on to timing the drill. Always practice safety first – make sure you know the correct distance for the ammunition you are shooting. Kyle uses frangible ammunition as it allows for closer distance and less splay. Kyle performs the Shoot 2, Reload, Shoot 2 Drill with a Ruger Security 9 pistol. #rugerdrillsE4
