M6G magnum

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). In addition, the weapon is issued with a KFA-2 x2 optical, smart-linked scope.

Performance wise, the M6G sidearm has a relatively low rate of fire, being able to accurately deliver two rounds per second or 120 rounds per minute, and a maximum of 240 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 M6G pistol 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 skill to use, and a person who can consistently lead and pace his shots will be able to take down targets with ease.

Disadvantages
The M6G, unlike the M6D, has a slower firing rate, 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 is produced in two known sub-variants, one found in Halo 3 and the other in Halo: Reach. It can be assumed that these sub-variants are used by different branches of the UNSC military.



UNSC Army variant
The Army's variant is semi-automatic and is capable of firing around 240 rounds per minute. It is issued with an underslung flashlight attachment, has a shorter, stockier barrel, a different slide and grip, and an electroless nickel finish.



UNSC Marine Corps variant
The Marine Corps' variant is of the same general size and proportions as the Army's variant, with the exception of a slightly longer barrel. It also features an electroless nickel finish. However, it lacks an underslung flashlight. Although it is semi-automatic, the Marines' variant has a slower rate of fire than its Army counterpart, but has superior accuracy.

Changes from Halo 3 to Halo: Reach

 * Features a usable KFA-2 x2 smart-linked scope over the barrel.
 * Has reticule bloom, like most weapons in Halo: Reach.
 * Nearly doubled rate of fire.
 * Has a differently designed slide, grip, and magazine.
 * Has an unusable flashlight attachment.
 * Slightly shorter barrel.
 * Different firing sound.
 * Different reloading and melee animations that are very similar to those of the M6D from Halo: Combat Evolved, wherein the SPARTAN flips the weapon in the air after striking.

Influences
One possible influence is the Desert Eagle. Though their outward appearances are different (though the M6G's overall shape resembles that of the Desert Eagle Mark XIX), 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; on the Desert Eagle, this is due to gas operation rather than recoil operation. The design of the M6G does not actually allow for recoil operation; the barrel assembly does not lock up when the slide goes forward and unlock when the weapon is fired like a modern recoil-operated pistol would.

Another likely candidate is the H&amp;K P7 series or the Steyr M.

Yet 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.

Multiplayer

 * Wielding a pair of Magnums performs quite well against shielded targets, but is restricted due to their rate of fire. Dual-wielding a Magnum with other weapons such as an M7/Caseless Submachine Gun or a Plasma Pistol is also quite effective as the SMG depletes shielding quickly, while the Magnum finishes the target off; a Plasma Pistol's charged shot will completely drain any shielding system allowing the Magnum to perform the lethal head shot. In Reach, the faster rate of fire means that it can be used as an effective close quarters weapon as opposed to a back up weapon. Fire at opponents' body to drain their shields and use the remaining shots at their head.

Trivia

 * The stamping on the side incorrectly labels this as a Model 6C rather than a Model 6G. In Halo: Reach it's labeled as a Model 6B.
 * Like the M6D, the M6G has Asian calligraphy stamped on the barrel, but in this case, they are Korean Hangul, not Japanese Kanji. It is also featured on the bottom of the magazine. The symbol 일곱 (il-gohb), when reflected, translates to 7.
 * The words 'Misriah Armory' are written on the side. Similarly, the M6G has a Marathon symbol on the grip near the back.
 * Aesthetically, the M6G seems to be a combination of M6C's way of being held, and the M6D look and structure.
 * It is incorrectly labeled in the instruction manual as having 12 rounds per magazine, instead of the actual 8.
 * In Halo 3, when a full magazine is emptied, the slide of the M6G does not lock back to wait for another fresh magazine to be inserted.
 * It costs 1615 cR. to make one Magnum pistol, more than a Flamethrower, which costs 1520 cR.
 * A single M6G shot does 15 damage points to a player, based on the 115 hit points a player is given (70 shielding points, and 45 body points).
 * A M6G pistol round does about twice as much damage as a MA5C Assault Rifle round; on Heroic difficulty, a human Marine dies after 24 assault rifle shots, or after 12 pistol body shots.
 * A shot from the M6G pistol is marginally less damaging than a 3-round burst from the Battle Rifle; it takes 12 pistol shots or 10 3-round bursts from the Battle Rifle to kill a human Marine on Heroic difficulty.
 * In an old poster related to the human weapons of Halo 3, the M6G is incorrectly labeled as an M6C.
 * This variant of the M6 appears to be a homage to the 44 Magnum Pistol in Marathon. Using the same number of rounds per magazine, the same rate of fire and duel wield capability and sporting an unusable attachment (44 with its scope and M6G with its laser sight). Even the reload time is the same.
 * In Halo: Reach, Spartans wielding M6Gs use a nearly identical melee animation to the M6D pistol in Halo: Combat Evolved. Elites however, will use an animation similar to that used by both species in Halo 3.
 * The M6G features unusable devices in both games it appears in. The scope is unusable in Halo 3 for gameplay reasons and the flashlight is unusable in its Halo: Reach incarnation.
