A shotgun, also called a "scattergun," is a firearm designed to shoot a multitude of lead or steel balls of varying sizes. This makes it very effective at hunting game, greatly increasing the weapon's hit potential. However, the accuracy and power found at close range starts too diminish as the target gets farther away. Shotguns designed for the military's use are often called "combat shotguns."
The caravan shotgun is a short shotgun in which one barrel is mounted on top of the other, also known as an "Over/Under shotgun". The iron sight is a screw which holds the action release lever to the receiver.
It can be a bit confusing when trying to aim with the iron sights, the target has to be placed behind the screw that is somewhat blocking the player character's view. There are four horizontal marks on the screw; the target needs to be behind the second mark from the top. Because of that, and its large spread, this makes it very difficult to utilize slugs effectively.
