Volley gun
Two notable artillery-sized volley guns were developed in the mid-19th century, although neither was particularly successful in practice. Developed in the 1860s and based on an 1850s design by a captain Fafschamps, the French mitrailleuse is an example of a multi-barreled volley gun that could fire all of its barrels simultaneously or sequentially over a short period of time. Also developed in the 1860s, General Origen Vandenburgh of the New York State Militia designed a weapon that had eighty five parallel .50 caliber rifle barrels. After failing to sell the weapon to the United Kingdom, he reportedly sold a small number to the Confederate States of America, although there is no record that they were actually used. One Vandenburgh gun was located at Fort Fisher, North Carolina, and another reportedly at Salisbury, NC.
Common Army
The development of handguns went through two different stages. In 1870, the revolver was introduced in 1870, in place of the previous single-shot, muzzle-loading pistol. These were the two high caliber guns developed by Leopold Gasser: the 11mm M1870 Army revolver and, four years later, the improved model M1870/74. In addition, there was also the 9mm infantry officer revolver, the Gasser-Kopratschek M1872, and the 8mm Rast & Gasser M1898. Subsequently, the multi-shot repeater pistol was introduced, namely the 9mm Roth–Steyr M1907 and Steyr M1912. Both guns have a rigidly locked recoil for chargers with a magazine for 10 and 8 rounds, respectively, in the grip.
