M6B magnum
From Halopedia, the Halo wiki
Template:Ratings The M6B Handgun[1] is a United Nations Space Command firearm.
It is a variant of Misrah Armory's M6 Series of sidearms, and is noted for its comfort and its electronic KFA-2 x2 scope. However, it sees only widespread distribution in civilian security forces such as police, not mainstream UNSC military units. The M6B Handgun fires 12.7mm x 40 projectile ammunition, possibly semi-armor piercing (SAP).
