Big Boomer

The  is a unique weapon in Fallout: New Vegas. It is a unique variant of the sawed-off shotgun.

Characteristics
Similar to the Double-barrelled shotgun from Point Lookout, It fires two shells with one pull of the trigger, consuming ammo twice as fast, but dealing significantly better damage in the process. The gun has its name written on the side of it.

Locations
The Big Boomer is carried by Old Lady Gibson, who resides in the Gibson Scrapyard. This gun can be found by killing Old Lady Gibson and looting it from her body.

Punch her to make her hostile and when she pulls the gun out, take out a fairly strong gun and shoot on her right arm, the gun should drop and if you holster your weapon she should go back to being friendly. Be careful not to kill any dogs or you will have to kill Old Lady Gibson.

Alternatively, you could pickpocket all of her 12 gauge rounds, then reverse pickpocket a 9mm pistol and a few 9mm rounds into her (other guns and their corresponding ammo should work too, with the obvious exception of those which use 12 gauge rounds). Wait a few days and she should equip the 9mm pistol, allowing you to pickpocket the Big Boomer from her.
