M6A magnum

The M6A Handgun is a United Nations Space Command firearm.

It is a variant of Misriah Armory's M6 Series of sidearms pistols, and is noted for its comfortability and lightweight. 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). But the M6A might actually fire a smaller round because they are more comfortable to shoot.

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