The M6C Personal Defense Weapon System,[1] otherwise known as the M6C Magnum Sidearm, is a United Nations Space Command sidearm and is one of the variants of Misriah Armory's M6 handgun series.


Weapon Design[]

The M6C Magnum Sidearm is a short-medium range UNSC handgun that was distributed to members of the UNSC Marine Corps, particularly members of vehicular crews. This model has been up-sized(~117%) to be used by Spartan’s in MJOLNIR armor. The Spartan issue pistols can still share magazines with the standard-issue variants. The M6C is a semi-automatic, recoil-operated, magazine-fed handgun. It has a double-action only(DAO) trigger, meaning one pull of the trigger will cock and release the weapon's hammer/striker. There is no need to cock an external hammer for the weapon to fire.

There is a small, red rectangular box on the flat back of the slide that likely protrudes as the chamber is loaded. The safety is located at the back of the slide on both sides and must be switched off in order to fire the weapon. To reload, the empty magazine can be removed by the magazine release button located on the grip.


The M6C Magnum, uses M228 SAP-HP rounds.[2] These rounds have a jacket of copper or nickel which encloses a more frangible metal projectile that will deform shortly after penetration. When the round hits a hard object such as body armor, the jacket will temporarily help maintain the shape of the projectile so that it has a better chance of penetration. A second impact against bone or solid muscle mass inside the target's body is usually enough to complete the jacket's rupture, at which point the projectile shatters into smaller pieces, causing a large number of wound channels and maximizing damage.

These rounds are typically more effective against infantry as opposed to armor-piercing rounds due to a larger dump of KE, resulting in better stopping power. Ammunition packets for the M6C Magnum are labeled in the same blue color as all other M6 sidearm ammunition packs; however, each ammunition pack has a different shade and text to indicate the type of ammunition inside.


The M6C PDWS is a defensive sidearm, allowing for successful engagement at close range. The M6C Magnum's 12.7mm ammunition does a considerable amount of damage to soft targets. This, coupled with its high rate of fire and its ability to kill with a single headshot makes the M6C a capable weapon against unshielded infantry over short distances.


The M6C PDWS, when compared to the strength of other versions of the M6 Magnum series, is considered the weaker of the military issued sidearms. Its inability to engage infantry at medium or long ranges is the weapon's main disadvantage, for this reason the M6C is mostly issued to vehicular crews as the weapon's nature serves a more passive defensive role. The M6C's default ammunition has no secondary effects, limiting its effectiveness against heavily armored infantry.


One possible influence on the design of the weapon is the Walther P99. Another possible influence could be the FP-45 Liberator, a weapon designed in the United States during World War II. The long grip, but short barrel is an obvious feature.



  • In campaign, the M6C is best used when dual wielding another weapon; two M6Cs will be very effective at quickly eliminating unshielded Covenant.
  • Dual wielding two M6Cs is a good tactic against Drones due to the Drone's low damage resistance, and the relatively light recoil compared to the M7/Caseless Submachine Gun.
  • Headshots (which are always a 1-hit kill except against shielded or helmet-wearing enemies) are essential for effective use of the M6C, since torso shots do mediocre damage. A single M6C bullet does about the same amount of damage as a Battle Rifle round, except the M6C is semi-automatic and has a magazine capacity of 12 rounds whereas the Battle Rifle fires in bursts and uses 36 round magazines.
  • Dual wielding the M6C with a Plasma Pistol is arguably the best combo in the game.


  • If you have no other option available, dual-wield the M6C with another weapon to maximize your chances until you find a weapon that you can use.
  • If forced to use a single M6C be sure to get up close to the enemy player, fire to lower his shields and then melee attack for an effective kill.
  • Using the Plasma Pistol with the M6C is often one of the easiest ways to assure a kill.


  • A suppressed variant is available to UNSC Special Forces.
  • The Halo 2 post-game carnage report breakdown tab on Bungie.net shows the weapon as "Magnum M6G Pistol," even though the game manual states it is the M6C model.
  • If aimed directly at an enemy's head a red dot will appear in the center of the crosshair. This occurs with any precision weapon from Halo 2 onwards.
  • The pistol is a dark grayish color rather than a whitish-silver color like other variants, but some versions have been noted to have a silver color, like John Forge's pistol.
  • The M6C has no visible hammer, and it can be inferred that it has a concealed hammer or spring-loaded striker, similar to that of a Glock or Springfield XD handgun.
  • The M6C's design looks similar to a Walther P99 pistol. The overall design is very much the same, however the M6C is much smoother and rounded than the Walther P99.
  • Inspects the files M6C texture can be seen that the sides have most of the engravings that are present on the M6G.
  • The M6C is able to fire twice as fast as a Covenant Carbine if you have a quick trigger finger. While this is very useful, it consumes ammunition at an extremely fast rate. So, do NOT use this as a primary weapon, but what pistols are designed to be: sidearms.
  • The M6C is the first weapon in the Halo series that is capable of a headshot that does not include a zoom function.
