The M6D Personal Defense Weapon System (abbreviated M6D PDWS),

The M6D Pistol is a common UNSC sidearm and was probably first put into service around 2524 (based on Fall of Reach). It is a model of the M6 series pistols that were distributed to members of the UNSC Navy and the Spartan-II Program. This particular M6 variation is featured in Halo: Combat Evolved and cameos in a Halo 2 multiplayer map and is considered to be an extremely powerful weapon when compared to other M6 series weapons. It is mostly seen in the hands of crewmen and its flesh damage as well as accuracy and range are much higher than other M6 models. Its rate of fire is also rather high. The M6D is a semi-automatic, recoil-operated, magazine-fed, large-bore handgun that is controllable enough to fire rapidly, although at the cost of accuracy. It is most likely striker-fired, due to the fact that there is no external hammer.

It fires the M225 SAP-HE (Semi-Armor Piercing, High Explosive) rounds from a 12 round magazine. It has a decent high rate of fire (3.5 rounds/sec or 210 rounds/min) with a very long effective range, being able to hit a target accurately up to about 90-95 meters. Its maximum range, however, is 122.5 meters (maximum range being how far the bullet can actually travel). The weapon’s accuracy is quite precise and has a very small shot spread at close and medium ranges. This, combined with its decent damage against current shield systems, makes it an acceptable weapon of choice when faced with shielded opponents. It is, however, even more effective against flesh and hard/soft armor, being able to kill most targets in 1 shot to the head or a couple of shots to the body (depending on the target).
