double-tap

A double tap is a shooting technique where two shots are fired in rapid succession at the same target with the same sight picture (as opposed to the controlled pair, where a second sight picture is acquired for the second shot). 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.
