The Colt Revolving Belt Pistol or Navy Pistol, sometimes erroneously referred to as "Colt Revolving Belt Pistol of Naval Caliber" or "of Navy Caliber" (Naval is heavy gun and Navy Size Caliber was termed later for another Colt model), is a .36 caliber, six-round cap and ball revolver that was designed by Samuel Colt between 1847 and 1850. Colt first referred to this Revolver as the Ranger Size model, and then Revolving Belt, but the designation "Navy" quickly took over. After the Civil War, revolvers using fixed metallic cartridges came into widespread use.
