Guycot 40-shot Chain Pistol
The Guycot chain pistol was the development of two Frenchmen, Henri Guenot and Paulin Gay in 1879. It is chambered for a unique 6.5mm caseless rocket ball type cartridge in which the base of the projectile is hollowed out and contains the propellant powder and a primer. Upon firing, the entirely of the projectile exits, leaving nothing to be extracted or ejected from the chamber. Unfortunately for the Guycot’s military aspirations, this cartridge was far too small and underpowered to attract and serious interest and only a few hundred at most were made. These were divided between several models, including a 25-shot pistol, a 40-shot pistol like this one, and an 80-shot carbine.
