M1942 Sosso Pistol

The Sosso was an interesting design produced experimentally by FNA Bescia in Italy in very small numbers during World War II. It was a short-recoil operated design chambered for 9x19mm, and featured a particularly unusual magazine design. Instead of using a convention spring and follow, the magazine contained what is best described as a belt-feed. A loop of chain in the magazine held 21 cartridges, and rotated one position each time the pistol was fired. This doesn’t seem to have had any particular benefit over a typical magazine (it certainly cost more to make), but it an interesting idea:

An example of a Sosso form the collection of Geoffrey Sturgess was sold by James Julia at auction, which gave us the opportunity to see some outstanding photos. This particular example (serial number 8A) included a holster-stock; a concept which was on its way out of popularity by the time these were being made. In addition, Julia also published an Italian-language copy of a Sosso manual, which I have not yet have the chance to translate:
