The Sawed Off Shotgun is a weapon that appears in Uncharted 3: Drake's Deception. In the beta, the Sawed Off Shotgun was only available in the Co-op game modes.
In the game's campaign it has a varying maximum ammo count which usually stays at 10 or 12 but during certain times can have a much larger capacity. An example of this is when it is given to Nathan in Yemen, and the ammo count changes to 32.
The Blindfire Accuracy of the Sawed-Off Shotgun was reduced in Uncharted 3 Multiplayer as of Update 1.09 to prevent the exploitation of the gun's high blindfire accuracy while used in the air.
