The Diamondback DB380 Gen4 in .380 ACP is a compact, lightweight pistol engineered for everyday carry (Diamondback part no. DB0100E002). Diamondback Firearms builds it with a black polymer frame, a gun-grade stainless slide with a black nitride finish and a 2.8-inch barrel. The double-action-only, striker-fired mechanism pairs a zero-energy striker with a mechanical firing pin block, and a windage-adjustable rear sight with a white three-dot arrangement keeps aiming simple. It is a straightforward choice for concealed carry or as a backup gun.
