An Italian made combat shotgun with semi-auto firing capabilities. Its unique design and black frame make it a popular weapon for movies, TV, anime and other media.
The original SPAS 12 was produced by the Franchi Italian firearms company intended for law enforcement and military use. It has made countless appearances across all types of media, especially in video games, as a serious weapon one step up from garden variety shotguns. One of the SPAS' signature features is a semi-auto select fire that allows it to shoot without pump action between rounds. This has been interpreted sometimes in media as fully auto, but it allows the gun for fast firing.
Since the weapon is no longer in production, its use doesn't require royalties or permission from other companies.
Roberta the maid from the Black Lagoon series uses a SPAS 12 disguised as an umbrella. The parasol is reinforced with Kevlar for protection from small arms fire and the shotgun occupies the place where the handle and shaft would be. She fires it one handed in semi-auto mode to avoid wasting time between shots with the pump action.
