A pump-action shotgun is a type of firearm that uses a sliding mechanism to load shells into the chamber. This design allows the shooter to manually cycle the action by pulling the fore-end back and then pushing it forward, which ejects the spent shell and chambers a new one. Pump-action shotguns are popular for their reliability and ease of use. These shotguns are commonly used for various purposes, including hunting, sport shooting, and home defense. They can fire different types of ammunition, such as birdshot, buckshot, and slugs, making them versatile for different shooting scenarios.
