DoubleTap derringers are modern, hammer-less, double-action, double-barreled, large caliber derringer designed for personal protection and manufactured by DoubleTap Defense, LLC.[5] They feature stainless steel ported barrels and aluminum or titanium alloy frames. They also hold 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.[6] Heizer Defense, the original manufacturer, has stated that they drew inspiration from the FP-45 Liberator pistol which was designed for use in France by the resistance against the Germans during World War II.[7]
Design
The DoubleTap is unique in that it carries two chambered rounds, one in each barrel. It also carries two additional rounds (on 2 round Bianchi Speed Strips) in the grip which allow for reloading. The ambidextrous thumb latch releases the action but does not have ejectors, the spent rounds have to be manually removed if they do not fall free so that the two backup rounds can be loaded.[4]
The weapon features a patent pending double-action ball bearing trigger system.[8] Additional features include a lightweight frame made of either titanium or aluminum and a hammer-less, no-snag design that make the DoubleTap easy carry and draw from a pant pocket,[8] and also allows it to be fired through a coat or jacket pocket.
Production
The DoubleTap was originally marketed under the name Heizer DoubleTap but in October 2012 DoubleTap Defense announced that they were looking for a new partner to manufacture the pistol.[9] In a statement released on November 7, Heizer Defense stated that the business relationship with the creators of the DoubleTap had never materialized as the economics proposed "did not forecast a successful business relationship."[10] A month later, it was announced that Azimuth Technology in Naples, Florida had been selected to manufacture the pistol.[9]
