10mm Submachine Gun (Fallout: New Vegas)

The 10mm submachine gun is a weapon

Characteristics
The 10mm submachine gun is a one-handed automatic weapon. It has a high damage-per-second (DPS) and low Damage Threshold. The high spread of this weapon requires the wielder to be at close ranges for all of the rounds fired to impact on the target. With full automatic fire and a 30-round magazine, the SMG performs well in close quarters combat.

Durability
The 10mm submachine gun can fire a total of about 2495 standard rounds, the equivalent of 84 reloads, or 63 reloads when modified with extended magazines, from full condition before breaking.

Variants

Behind the scenes
Joshua Sawyer commented that the decision to place 10mm as opposed to 9mm weapons in vaults was intentional, noting their appearance as more "vaulty/futuristic."
