Cosmi Semi-Automatic
Cosmi Americo & Figlio · Shotgun · In Production · 1925
Also known as: Cosmi Semi-Automatico, Cosmi Lusso
Overview
The Cosmi is a hand-built, long-recoil semi-automatic shotgun made by the Cosmi family in Ancona, Italy, and one of the oldest continuously produced self-loading shotgun designs in the world. Patented by Rodolfo Cosmi in 1925, it breaks open like a side-by-side - the barrel tips down - and is loaded through a tubular magazine hidden inside the buttstock rather than under the barrel, giving it exceptional balance. Each bespoke gun is assembled from over 100 hand-fit parts and engraved to order.

Background
The Cosmi is one of the oldest continuously produced self-loading shotgun designs in the world, patented by carpenter-turned-gunmaker Rodolfo Cosmi in 1925 and still hand-built by the fourth generation of the family; its tubular magazine hides inside the buttstock, and owners have included the King of Italy and numerous heads of state.
