M6H magnum

The M6H Personal Defense Weapon System (M6H PDWS) is a handgun in service with the UNSC. It is part of Misriah Armory's widespread M6 series. The M6H was infrequently in service 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 12.7×40mm ammunition. The M6H is effective at reasonably long distances as well as its preferred close-to-medium-range.

M6H2 Personal Defense Weapon
The M6H2 variant had entered service by at least 2557 and was issued to all branches of the UNSC. It has a serial number of "00MA0100062473" and sports a black polymer finish. Like the base M6H, the M6H2 is semi-automatic, recoil-operated and magazine-fed, but has an increased 12-round magazine capacity. The variant also boasts increased accuracy and is most effective with precision aiming. It features a smoother slide design and a Projection sight (in place of the venerable KFA-2 x2) to support smart scope functionality. In 2557, this weapon had a Ruptive skin approved by the UNSC Ordnance Commission.

M6H2 Variants

 * Whispered Truth: A cut-down M6H2 magnum without a smart scope system, under-barrel flashlight, or forward trigger guard. It also has a custom slide and can mount a suppressor. This variant sports a 18-round magazine. Unlike other pistols Whispered Truth fires in three-round bursts. The slide reads "Semper Vigilans" (Always Vigilant), the motto of the Office of Naval Intelligence.
 * Gunfighter Magnum: Lightweight competition pistol carried by Spartan operators who prefer a no-frills backup firearm. Quick draw Magnum with fast-reload magazines. Iron sights only, no Smart-Link module is attached.
 * Tactical Magnum: Whisper-quiet tactical pistol loaded with armor-piercing rounds, tailored for Spartan force reconnaissance missions. Match grade Magnum with integral baffle-free suppressor and 2× full-VISR Smart-Link.
 * Buck's Magnum: A Magnum with the Gunfighter body, Whispered Truth finish, and a front iron sight that is seen on the Projection Sight, appearing to have been attached separately.

M6H2 Attachments

 * Extended Magazine: Increases both ready and reserve ammunition capacity by 50%.

Changes from M6H in Halo 4 to M6H2 in Halo 5: Guardians

 * Less bloom/greater accuracy.

 * Has a limited range of fire.
 * Can kill Promethean Crawlers and Grunt Minors in a single shot.
