There is a loop on the end of one side of the retention cords. Depending on the design of the sling, either the middle finger or the wrist is placed through a loop on the end of one cord, and a tab at the end of the other cord is placed between the thumb and forefinger. The sling is swung in an arc, and the tab released at a precise moment.

The slungshot was often used as a civilian or improvised weapon; however, the rope was much shorter for use as a weapon. The cord is tied around the wrist, and the weight is carried in the hand or the pocket of the user. A slungshot may be swung in a manner similar to that of a flail or a blackjack.
