Soviet Made: Special Underwater Pistol SPP-1

This Special Underwater Pistol SPP-1 (Spetsialnyj Podvodnyj Pistolet) was especially developed for Soviet Navy in 1960 by the TSNIITOCHMASH organization. The non-automatic 950 gram 4.5×40R caliber handgun comes with four barrels and double-action trigger to shoot long mild steel bullets to pierce water effectively. The 40mm rimmed bottlenecked cases makes SPP-1 a perfect underwater gun.
