I will also assume that you are using commercial ammo or that you are a careful reloader. Fire the gun several times paying special attention to whether the slide cycles fully.

A view of the break-action of a typical double-barrelled shotgun , with the action open and the scalloped triangularly shaped extractor visible at the base of the two barrels.
The opening lever and the safety catch can also be clearly seen. An extractor is a part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired.
When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber. Extractors can be found on bolt action , lever-action , pump action , semi-automatic and fully automatic firearms.
Break-action shotguns , such as those with single or double barrels, typically have an extractor that operates when the action is broken open. Extractors are also found on revolvers , removing cases either singly as in a fixed-cylinder single action revolver or all at once as in a double action revolver with a swing-out or top-break cylinder.
For rimless cases, an extractor groove in the ammunition may serve as the point from which the extractor works.
For rimmed cases, the rim of the cartridge most commonly serves as the point from which the extractor works. In bolt-action, lever-action, pump-action, and semi- or fully automatic firearms, extractors typically work in conjunction with ejectors to remove completely a fired, empty cartridge case from the weapon.
The extractor removes the cartridge case from the chamber, essentially pulling the case to the rear. At some point in the rearward travel, the case typically makes contact with the ejector, which "kicks" the expended case out of the firearm, making room for an unfired cartridge to be loaded. Extractor - The extractor has a notch into which a cartridge rim fits snugly. It pulls the agent cartridge backward with the slide.
