M6A magnum

The M6A Handgun is a United Nations Space Command firearm.

It is a variant of Misriah Armory's M6 Series of sidearms, and is noted for its comfortability. However, it sees only widespread distribution in civilian security forces such as police, not mainstream UNSC military units.

The M6A Handgun is believed to fire 12.7mm x 40 projectile ammunition, possibly semi-armor piercing (SAP).

It has also been around for 140 years before 2552, meaning it was made in 2412.
