Heizer Defense, a new gun maker from St. Louis, Missouri, has developed a nifty derringer type pistol. The Heizer Defense DoubleTap is chambered in .45 ACP and has two barrels in an over/under configuration. The frame is made of titanium and the trigger is double action. A thumb latch automatically opens and ejects the chambered rounds or empty cases. Ported barrels, to reduce recoil at the expense of making a noisy short barrel gun even more noisy, two round storage in the grip and snag-free design are nice touches.
The company could have gone the cheaper polymer route, but instead with Titanium which makes me think they are positioning this as a premium-priced weapon.Related
