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 features an un-conventional top-mounted magazine, which lies parallel to the weapon's barrel. It boasts a high damage-per-second, but suffers from a small magazine capacity and a fairly large spread, however this spread is still less than that of the 10mm SMG (as of patch 1.3.0.452). It is also one of only three fully automatic weapons which are capable of being silenced, (the silencer is not to be confused with the 12.7mm pistol silencer, as they are not interchangeable), the others being the silenced .22 SMG and Sleepytyme (GRA).  Unlike 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 other 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 SMG and 9mm SMG.

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.
