M6A magnum

The M6A Magnum Sidearm is a United Nations Space Command ground firearm.

Now used mostly by the Civilian Security Forces, the M6A and M6B Magnum Sidearm are more comfortable to shoot then the other variants.

It is a model of Misriah Armorys M6 Series of sidearms.

Seeing as it is more comfortable to shoot, this may indicate a low caliber round, thus reducing recoil.
