9mm Submachine Gun (Fallout: New Vegas)

The 9mm submachine gun (SMG) is a weapon in Fallout: New Vegas.

Characteristics
The 9mm submachine gun is a small, yet capable weapon, able to empty a full magazine in under 3 seconds. The 9mm rounds don't deal as much damage as 10mm or 12.7mm rounds, but they're common and lightweight, making it even easier to spray-and-pray.

With the light bolt modification, this weapon deals an impressive 200 damage-per-second. However, it shares the common weakness of most automatic weapons in Fallout: New Vegas, in that much of its theoretical power is negated by the damage threshold system. In addition to losing much of its damage to the target's damage threshold, the high spread of the SMG requires the player to be at close range for all of the rounds fired to impact on the target.

Durability
The 9mm submachine gun can fire a total of about 2745 standard rounds, the equivalent of 92 reloads (or 46 reloads when modified with drum magazines) from full condition before breaking.

Behind the scenes
The 9mm SMG is based on the M3 submachine gun also known as the "Grease Gun", albeit with a shorter barrel than its real life counterpart.

Bugs
Sometimes when switching to the 9mm submachine gun the magazine will appear forwards of the barrel with the rest of its orientation correct. Upon reload the magazine position issue will correct itself. It appears to only affect the gun when the drum magazine mod is equipped.
