M6A magnum

"The A's and B's are way more comfortable to shoot, but you don’t see many of them outside of civilian security forces anymore."

The M6A magnum is a standard-issue United Nations Space Command sidearm.

Background
The M6A magnum is a variant of Misriah Armory's M6 series of pistols, and is noted for its comfort. By 2552, it has been largely phased out of military use and only sees widespread distribution in civilian security forces.

The M6A fires 12.7×40mm projectiles, and has a black polymer finish. Unlike other models such as the M6D or the M6G, it is not up-sized to fit MJOLNIR armor.
