A "Pump-Action" refers to a type of firearm mechanism commonly used in shotguns. This design allows the shooter to manually cycle the action by pulling the fore-end of the gun back and then pushing it forward. This motion ejects the spent shell and chambers a new round, making it a reliable choice for hunters and sport shooters alike. The pump-action mechanism is popular for its simplicity and effectiveness. Many well-known shotguns, such as the Remington 870 and Mossberg 500, utilize this system. It provides a satisfying sound and feel, often associated with power and readiness in various shooting scenarios.
