Thirty years ago I got one in 12GA and used it a lot.
It's the forerunner of the Benelli as it works on the inertia principle.
Certainly it's not the most elegant automatic shotgun ever produced but it's extremely well made and functions flawlessly.
Indeed I prefer a nice 20GA Cosmi but I shall be glad in getting one in my rack.
