Franchi SPAS-12

The SPAS-12 is a combat shotgun that was manufactured by the Italian firearms company Franchi S.p.A. The SPAS-12 is a dual-mode shotgun, meaning it can be set to cycle either semi-automatically or through pump-action. The SPAS 12 was designed to function primarily as a semi-automatic firearm, with the pump-action mode used to reliably fire low-pressure ammunition such as tear gas rounds or less-lethal bean bags. The firing mode is switched by pressing a button under the foregrip and sliding the foregrip slightly forwards or backwards until it clicks into position. However, the pump-action mode was slow and awkward compared to traditional pump-action guns because of the complex changeover mechanism and friction between the foregrip and the hand-guard.
