pumppüss
Pumppüss is a term of German origin that translates to "pump gun." It refers to a type of firearm, most commonly a shotgun, that is operated by a forearm pump action. This action involves moving a sliding fore-end, typically located beneath the barrel, back and forth. The rearward movement of the fore-end extracts and ejects the spent cartridge case, while the forward movement loads a fresh cartridge from the magazine into the chamber and readies the firing mechanism. This design allows for relatively rapid firing of multiple shots without the need to break grip or change posture significantly. Pumppüss firearms are known for their reliability and versatility, making them popular for hunting, sport shooting, and law enforcement. The operation is generally considered intuitive, contributing to their widespread use. Variations exist in the length of the pump stroke and the capacity of the tubular magazine, which is often located beneath the barrel.
