M6H magnum

The M6H Personal Defense Weapon System is a handgun in service with the UNSC. It is part of Misriah Armory's widespread M6 series. The M6H was in service as an officer's model as early as 2526 and was made the standard-issue sidearm of all UNSC personnel in 2555.

Specifications
The M6H is a semi-automatic, recoil-operated, magazine-fed handgun. It is an up-sized model (17% larger than standard versions) with a smart-linked KFA-2 x2 scope and an electroless nickel finish. It fires the M6 series' standard 12.7x40mm ammunition. The M6H is effective at reasonably long distances as well as its preferred close-to-medium-range.

M6H2 Personal Defense Weapon
A second iteration of the weapon exists, designated M6H2. This variant sports a black polymer finish and a 12-round magazine. Functionally, the M6H2 performs identically to its predecessor aside from its increased accuracy of rapid fire and the benefit of a deeper magazine capacity. Aesthetically however, the weapon bears drastic modifications to its body, with essentially nothing identical. Most notable of these modifications include an entirely different slide design, and a completely reworked top-mounted module to support Smart Scope functionality.
