The SPAS-12 was designed in the late 1970s by the Italian company Luigi Franchi Spa as a special purpose, military and police close combat weapon (actually, SPAS stands for Sporting Purpose Automatic Shotgun, or Special Purpose Automatic Shotgun, depending on the source). It featured a selective action for greater versatility, and can be used as a gas operated semi-automatic repeater or as a manually operated pump action repeater, depending on the mission and ammunition used.
File:Franchi-SPAS-12 is very often shown as a pump action shotgun firing buckshot. It's a combination action shotgun, capable of pump or semi-auto with the pressing of a button. Usually, the gun is only used in pump mode in the real world when underpowered shells are used. Only full loads are capable of operating the semi-auto gas system. Also, in Semi Auto mode, it has a problem cycling even Hollywood "hot" blanks with a Blank Firing Adapter. Since 2000, production has ceased.
