9mm Submachine Gun (Fallout: New Vegas)

The 9mm submachine gun (SMG) is a weapon

Characteristics
The 9mm submachine gun is a small, yet capable weapon. With the light bolt modification, this weapon deals 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 Courier to be at close range for all of the rounds fired to impact the target.

Durability
The 9mm submachine gun can fire a total of about 2,745 standard rounds, the equivalent of 92 reloads (or 46 reloads when modified with drum magazines) from full condition before breaking.

Behind the scenes
Joshua Sawyer stated that the weapon looks like a "9mm Grease Gun, like sort of compacted" and called it a "cool distinctive little weapon."

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.
