Caliber: .357 Magnum. Capacity: 6 rounds. Barrel: 4". Grip: Walnut laminate, oversized. Sights: Fully adjustable rear, fiber-optic front. Features: The DASA is the next evolution of the K6s. The DASA is outfitted with a double- and single-action trigger mechanism. Kimber’s K6s revolvers feature the purportedly smallest cylinder capable of housing 6 rounds of .357 Magnum at 1.39" diameter, making for a very slim and streamlined package.
