M6B magnum
From Halopedia, the Halo wiki
The M6B Handgun is a United Nations Space Command firearm.[1]
Background
The M6B is an 'Officers Model' variant of Misriah Armory's M6 Series of sidearms pistols, and is noted for its comfort and KFA-2 x2 scope. However, it sees only widespread distribution in civilian security forces such as Law enforcement and Governmental security; not mainstream UNSC military units. This model began production around 140 years before 2552.
The M6B Handgun fires 12.7mm x 40 projectiles, and has a hard chrome finish. Unlike other models such as the M6D or the M6G, it is not upsized to fit MJOLNIR armor.
