Video Review: Diamondback DBX57 With Hi-Lux TD-3C Red Dot By: Brian Schraeder

Diamondback BDX57 pistol on a target with 3 boxes of ammunition by Brian Schraeder

Small, sleek, lightweight, and packing a powerful punch, the Diamondback DBX57 is the ideal choice for a truck gun, backpacking, or home defense. The DBX57 uses the same 20-round magazine as the FN Five-seveN pistol, which makes for a powerful combination utilizing the same magazines.
