Combat Shotgun (Fallout 3)

The Drum-Magazine Combat Shotgun is a common Fallout 3 weapon.

Characteristics
The weapon appears to be functionally identical to its predecessors while its design has changed significantly. It now resembles the famous WWII era Soviet PPSh-41 submachine gun with a wooden stock and an Armsel Striker-style drum magazine mounted very close to the muzzle of the gun as opposed to being made entirely out of metal with a bullpup configuration. The unique form of this gun is The Terrible Shotgun.

Strategy
If you want to see the Combat Shotgun at its best, wait for a dog/mole rat to leap up at you, quickly enter V.A.T.S. and fire at the head.

The Combat Shotgun is a very effective choice for fighting in close-quarters, such as inside of buildings. It really shines in the metro tunnels, where the majority of enemies encountered rely upon melee attacks (such as Mirelurks and Feral Ghouls). Two close shotgun blasts to the face will kill most Mirelurks. Feral Ghouls are very easily snuck up on for shots to the back of the head; alternatively, when they notice you, they will growl before charging at you, giving you several seconds to allow them to come closer before shooting them in the head.

Close sneak attack criticals with this weapon (outside of V.A.T.S.) with the Better Criticals perk (or maybe even without it) can effortlessly dispose of high-level enemies such as Deathclaws and Sentry Bots in a single shot. This is because outside of V.A.T.S., the critical damage bonus is applied to each pellet individually; the Combat Shotgun fires 9 pellets, each of which get the +27 critical bonus (40.5 with Better Criticals). So 9 x 27 = 243 (or 364.5 with Better Criticals) total critical damage. Add in the weapon's standard 55 damage, and then double the total because of the sneak attack bonus, and you have a pretty huge amount of damage dealt to your unfortunate, unsuspecting foe.

The typical vault dweller should know that the game script gives every bullet an exact amount of force that pushes against an object. For example, you can blast a bottle off a shelf with a gun because of it's scripted force. That being said, shotguns fire nine bullets. Each bullet's force is cumulative. When an enemy dies, it enters a ragdoll state, able to be affected by forces. When the shotgun fires a fatal blast to an enemy, the force happens to shoot a corpse further than a typical gun would. This is easily demonstrated by giving a close-range (does not have to be point-blank, though point-blank shots are sometimes effective) shotgun blast to a super mutant/Yao Guai's head. Occasionally, the force is applied in a direction so as to fling the corpse 5-6 feet in the air. Of course, all the bullets must hit the corpse to have this effect. Raiders, though much less commonly, have this effect. This is probably due to the fact that raiders arent big enough to provide a force the bullets can act against.

Companions
Charon wields an apparently unique shotgun that does not deteriorate, used to have infinite ammo, and very little spread. It cannot be interacted with. This makes it possible for Charon to "snipe" with the shotgun.

Trivia
Judging by its look, this shotgun's appearance was inspired by existing firearm(s):
 * The PPSh-41 (Pistolet-Pulemyot Shpagina) - the overall appearance, fire selector switch located inside the trigger guard, the barrel's protruding muzzle-brake and the drum magazine. The way the reloading procedure is operated also points to the real PPSh-41. However the real life counterpart is loaded with 7.62x25mm Tokarev cartridges and has a 71-round magazine.
 * The Pancor Jackhammer, which is another shotgun that feeds from a drum and has a similar muzzle shape.
 * The Armsel Striker, which has an almost identical magazine.
