Cosmi Americo & Figlio is an Italian shotgun manufacturer located in Ancona, Italy. The company manufactures semi-automatic shotguns under the name Cosmi. Only approximately 7,500 guns have been manufactured since 1930, and individual guns are unique enough that parts are often not interchangeable.[2] Each part is individually serial numbered. The shotgun is available in three calibers (gauges): 12, 16, 20, and .410 bore.
