M6 series

"The M6 has been in service for about a hundred and forty years… it’s amazing to think how little it has changed in all that time."

- Anonymous UNSC serviceman



The M6 Series is a series of short-barreled weapons produced by Misriah Armories.

Introduction
They have seen widespread distribution through the United Nations Space Command Defense Force as lighter firearms, although they are not seen as primary weapons because of their lighter penetrating power compared to larger weapons and smaller magazine capacity, and are mostly issued to officers and vehicle crews.

They have seen usage in the UNSC for almost 140 years, and have been used in almost every conflict since then.

Characteristics
The M6 series weapons are recoil-operated and magazine-fed, and typically fire 12.7mm x 40 projectile ammunition, and despite the large caliber, oftentimes "exotic" ammunition is not utilized. They are also remarkably large and overpowered to an extent, appearing to be redolent of a cross between a pistol or a rifle in size. In addition to power, the M6 line of weaponry is designed to be rugged and reliable, and the guns are able to remain operational after Slipspace transitions and high-g aerial maneuvers. However, the heavy weight limits its distribution amongst personnel, and the M6 weapons have a tendency to drop casings on the wielder's foot, leading some UNSC personnel to favor the M7/Caseless Submachine Gun which operates on a caseless system.

They have remained remarkably unchanged during its decades of service, although there are a large number of variants, such as the A, B, C, D, G, and J variants. The M6 series handguns are issued in three different finishes: hard chrome, black polymer, and electroless nickel.

Trivia

 * Despite constant comparison with the real world Desert Eagle pistol for their sharing of appearance, size, and ammunition calibers, the M6 remains drastically different for being recoil-operated instead of the desert eagle's unique gas operation.
 * The M6C/SOCOM and M6D are the only M6 Series variants thus far which utilize an aim assisting device during gameplay: a 2x magnification smart-linked scope. The Halo 3 M6G has a laser sight, although not usable during gameplay.
 * Despite using the same kind of ammo (with the exception of the M6C, which uses non-explosive ammunition), all of the three M6 pistols encountered in the games do different damage. This is due to game balancing.
 * In Halo: The Flood, Master Chief is given an M6D by Captain Keyes, and is able to carry it along with two other weapons. This is not possible (except for a glitch) ingame.
