The DoubleTap derringer is a hammerless, double-action, double-barreled, large caliber derringer designed for personal protection and manufactured by DoubleTap Defense, LLC.[5] It features stainless steel ported barrels and an aluminum frame that holds two extra rounds in the grip. The name comes from the double tap shooting technique in which two rounds are quickly fired before engaging the next target.[1] Heizer Defense, the original manufacturer, has stated that the gun was inspired by the FP-45 Liberator pistol, which was designed for use in France by the resistance against the Germans during World War II.[6]
