The M6H Personal Defense Weapon System is a M6 Series-handgun manufactured by Misriah Armory. It is an up-sized Officer's model and has a smart-linked KFA-2 ×2 scope and an electroless nickel finish.[3] It was adopted as the standard-issue personal sidearm of all branches of the UNSC by 2555.[4] In Halo 4, when using this pistol, a Spartan is able to melee, throw grenades, and switch to it much faster than other weapons, unlike other Halo games.[5]


M6H2 Personal Defense Weapon SystemEdit

This section requires expansion.

A variation of the M6H, designated M6H2 PDWS, is engraved on the side of the magnum in the Halo 5: Guardians Multiplayer Beta.[6] The M6H2 ditches the KFA-2 x2 smart-link module in favor of iron sights, and has an extended 12-round magazine.


Changes in the Halo 4 Weapon Tuning UpdateEdit

Main article: Weapon Tuning Update
  • The damage has been slightly increased, but still kills in six rounds.

Changes from Halo 4 to Halo 5: GuardiansEdit

  • Ammo capacity increased to 12 rounds.
  • Kills in five rounds.
  • Slower rate of fire.
  • Slightly faster reload time.
  • Loses the smart-linked scope; now has a HUD-projected sight, similar to iron sights.


  • It shares a laser aiming device on the underside of the gun with the M6G (B). However, you cannot use it in-game.
  • In CTF, the pistol becomes stronger when the player holds the flag. Normally, it takes at least six shots to kill another Spartan with a headshot. With the Flag, the player only needs five shots to kill another Spartan with a headshot.
