12.7mm Submachine Gun

The 12.7mm submachine gun is a weapon in Fallout: New Vegas.

Characteristics
More common at higher levels, the 12.7mm submachine gun is a heavy-duty large-caliber submachine gun (SMG). It has a high damage-per-second but suffers from a small magazine capacity and a fairly large spread.

Unlike most other submachine guns, the 12.7mm submachine gun is classified as a two-handed weapon; because of this, traveling with the weapon unholstered will slow the player character's movement speed. This also causes the weapon to be holstered on the back, rather than on the hip as with most SMGs. This also affects it with regard to the Jury Rigging perk, putting it in the same repair class as the service rifle and light machine gun, instead of with one-handed automatics like the 10mm and 9mm SMGs.

Durability
The 12.7mm submachine gun can fire a total of about 2495 standard rounds, the equivalent of 119 reloads, from full condition before breaking.
