M6G Personal Defense Weapon System

The M6G Personal Defense Weapon System, abbreviated as M6G PDWS and commonly referred to as the M6G Magnum Sidearm, is a United Nations Space Command infantry firearm, and is one of the variants of Misriah Armory's M6 sidearm series.

Design Details
The M6G sidearm is a semi-automatic, recoil-operated, magazine-fed, large caliber handgun. It is a later model of the M6 series sidearms that was distributed to officers and vehicle/weapon crews. The weapon has a polymer handle, along with a titanium alloy body and what appears to be an anti-corrosion nickel-plate finish. The sidearm fires the M225 SAP-HE (Semi-Armor Piercing, High Explosive) rounds from an 8-round magazine at a velocity of 427 m/sec (1302.35 ft/sec).

Performance wise, the M6G sidearm has a relatively low rate of fire, being able to deliver two rounds per second or 120 rounds per minute. It could achieve a maximum effective range of 50 meters and is very accurate and precise, proving itself to be the jack of all trades for close-to-medium range operation.

Ammunition
The M6G uses 12.7x40mm M225 SAP-HE (Semi-Armor Piercing, High Explosive) .50 Caliber ammunition loads. These rounds have a jacket of copper or cupro-nickel around the projectile while the projectile itself is hollow and filled with an explosive compound and a delayed-detonation impact fuse. When the round impacts a target, the jacket will initially help the projectile maintain its shape, allowing it to travel into the target before detonating almost immediately after impact, causing massive tissue damage and system shock. Probable reasons for using semi-armor piercing rounds instead of armor piercing projectiles are both to prevent over-penetration of hostiles and decreasing the risk of friendly fire during CQB and urban combat, and their devastating efficacy against soft targets. The explosive properties of the rounds render them decently effective against personal shielding systems and are also capable of damaging lightly-armored vehicles.

Advantages
The M6G is designed primarily for ruggedness and reliability. It is a very useful sidearm for close battles, and skirmishes. The UNSC has issued the M6 series of pistols as a standard sidearm because of its effectiveness against armor and shields, while retaining high impact force due to the high caliber and projectile mass. The M6G, like its predecessor the M6D, requires the same amount of skill to use, and a person who can effectually lead his shots, with a good understanding of how the weapon works will be able to take down targets with ease.

Disadvantages
The M6G, unlike the M6D, has a slower firing rate ('C' variant), and as such downing an enemy will take considerable time. If the person wielding it does not take into account of how the weapon works, or is unable to dodge enemy fire, they will be killed quickly by their opponent. Its eight-round magazine also puts the user at a disadvantage should a couple of rounds miss its target. A user must be precise and know at what range to engage the enemy or risk being killed.

Variants
The M6G comes in two variants, the 'B' variant, and the 'C' variant.



'B' variant
The 'B' variant is semi-automatic, and is also capable of firing almost twice as fast as the 'C' variant. It is issued with a smart-linked KFA-2 x2 scope, has a shorter, stockier barrel, a different slide and grip, and an electroless-nickel finish.



'C' variant
The 'C' variant is of the same general size and proportions, with exception to a slightly longer barrel and is 'not issued with a smart-linked KFA-2 x2 scope, unlike the 'B' variant. Although still semi-automatic, the 'C' variant has a slower rate of fire than its counterpart, but has increased accuracy.

Influences
One possible influence is the Desert Eagle. Though their outward appearances are different, both weapons are of similar size and caliber, and the slide of the M6G comprises the rear of the frame instead of the entire upper area, common with the Eagle. Another likely candidate is the H&amp;K P7 series or the Steyr M. Another possible influence on the design of this weapon was the FP-45 Liberator, a weapon designed in the United States during World War II. The long handle and short barrel is an obvious feature.

Campaign

 * The M6G is quite useful against most sparse targets that are encountered throughout diverse combat. Enemies such as Grunts and Jackals can be quickly dispatched with one well-placed shot to the head and enemies like Drones and members of the Flood can be dispatched in as little as 1-2 well-placed shots. The same can be applied to unshielded Brutes with one well-placed shot to the head.
 * The M6G's high-caliber rounds give it the ability to stumble non-berserk, unshielded enemies. This is most effective fired at the feet, when enemies like Brutes suffer the longest injury recovery time.
 * Experienced players can say that the M6G is one of the most underestimated weapons of Halo 3, and can make a solid headshot capable weapon if used correctly.
