A double tap or controlled pair is a shooting technique where two well-aimed shots are fired at the same target with very little time in between shots. Instruction and practice of the double-tap improves overall accuracy as shooters often do not have the gun fully extended on the first shot meaning the second of a double-tap is usually the better. The term hammer is sometimes used to describe a double tap in which the firearm's sights are not reacquired by the shooter between shots.
