Isaac Newton Lewis is best known for the Lewis light machine gun, but that was not his only foray into firearms design. He also patented two different types of handguns – one gas operated and this short recoil design. Very little information about this pistol is available, although it was apparently tested (and rejected) by the French military in the early 1920s. It is quite a bulky gun, although with that bulk does come a 15-round magazine capacity, and a rather clever unlocking system.
