DoubleTap derringer

The DoubleTap is distinctive for its two barrels, each carrying a chambered round. It also carries two additional rounds (on a 2-round Bianchi Speed Strip) in the grip which allow for reloading. An ambidextrous thumb latch releases the action but the pistol does not have ejectors; spent rounds must be manually removed if they do not fall free before the two backup rounds can be loaded.[4]

The weapon features a patented double-action ball bearing trigger system.[1][7] Additional features include a lightweight aluminum frame and a hammerless, no-snag design that make the DoubleTap easy carry and draw from a pant pocket,[7] and also allows it to be fired through a coat or jacket pocket. Azimuth and DoubleTap planned a titanium-framed version, but it never entered production.[1]

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.[8] 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."[9] A month later, it was announced that Azimuth Technology in Naples, Florida had been selected to manufacture the pistol.[8]

Early customers reported problems with "double strikes", a malfunction in the trigger system that would fire both barrels simultaneously. DoubleTap Defense ceased production in 2013, intending to develop a "Gen 2" design that would correct the issue, but financial problems and legal conflicts with Hornady and the unrelated DoubleTap Ammunition led the company to liquidate its remaining inventory and close its operations. No prototype of the "Gen 2" pistol was ever produced.[1]
