DoubleTap德林加手槍

DoubleTap是一款由美國雙連擊防務有限責任公司所研製及生產、專為個人防護用途的雙管式德林加手槍，有發射9×19毫米帕拉貝倫與.45 ACP口徑自動手槍子彈的版本。
該槍的名字來自於雙連擊（Double tap）射擊技巧，對攻擊目標的同一位置（或非常接近的位置）之上在短時間內連續射出兩發子彈。海澤防務已表示，他們汲取了來自FP-45「解放者」的靈感，該槍曾是二戰期間為供反抗納粹德國的法國游擊隊、反抗勢力使用而設計的武器。
雖然DoubleTap確實具有兩根槍管，兩發子彈卻不可同時發射，以免在美國菸酒槍炮及爆裂物管理局（ATF）規定下因被視為任何每次扣動扳機發射多於一發的武器而被定義為機槍。DoubleTap在第一次扣下扳機而發射第一發子彈以後，第二次扣下扳機並發射第二發子彈，進而達成雙連擊。

**設計**
DoubleTap的獨特之處在於其兩個膛室各自裝填的一發子彈，即每根槍管各一發。它還可在握把攜帶有兩發額外的子彈用以重新裝填。其雙手靈巧的拇指操作式閂鎖可釋放槍機並且拋出空彈殼，用以裝填兩發備用彈。
該武器設有正在申請專利的雙動操作滾珠軸承扳機系統。其他功能還包括由鈦或鋁製成的軍用規格底把和內置式擊錘，防絆的設計以便抽出武器。

**生產**
DoubleTap在市場上最初是以海澤DoubleTap（Heizer DoubleTap）的名字銷售，但在2012年10月，雙連擊防務有限責任公司宣佈他們正在尋找製造手槍的新合作夥伴。11月7日發布的一份聲明中，海澤防務表示，與DoubleTap的創造者的業務關係從來沒有被物化為經濟學提出的“沒有預測成功的商業合作關係。”一個月後，它宣佈位於佛羅里達州那不勒斯市的方位角科技公司（Azimuth Technology）被選中以製造手槍。
