The Diamondback Firearms DB9 Gen4 Semi-Auto Pistol is a single-stack subcompact handgun featuring the ZERO-Energy striker firing system with mechanical firing pin block to provide reliable ignition and safety. An FEA (Finite Element Analysis) slide and barrel enhance strength with less felt recoil. The steel trigger with dual connecting bars allows for a crisp, smooth, double-action-only trigger pull. The polymer frame keeps weight to a minimum. Slide, barrel, and internals are coated with a corrosion-resistant finish. Fixed 3-dot sights.
