M6B magnum

The M6B Handgun is a United Nations Space Command ground firearm.

It is a variant of Misriah 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 is believed to fire 12.7mm x 40 projectile ammunition, possibly semi-armor piercing (SAP), but the M6B might actually fire a smaller round because they are more comfortable to shoot.
