The Heckler & Koch Mark 23 is a heavy-duty .45 ACP semi-automatic pistol built around the USP-type mechanical recoil reduction system, which reduces recoil forces on the shooter and pistol components. Its steel slide, threaded polygonal barrel, and barrel O-ring provide durable operation and consistent barrel lockup for accuracy. The ambidextrous manual safety is separate from the decocking lever, allowing independent control of those functions. This configuration includes two 12-round magazines.
