Beretta Model 1915
Produced by Fabrica d'Armi Pietro Beretta S.p.A.
The Beretta Model 1915 or Beretta M1915 is a semi-automatic pistol manufactured by Beretta, designed by Tullio Marengoni who was the chief engineer in the company, to replace the Glisenti Model 1910 which had a complex and weak firing mechanism. It is the first semi-automatic pistol, manufactured by the company, and issued as a service pistol in Royal Italian Army during World War I. The total production of the Beretta M1915 is estimated about 15,600 during 1915-1918, and about 56,000 of Beretta M1915/1917. Some of the pistols were also used in World War II until 1945. Its open slide design later became the characteristic for other Beretta pistols such as Beretta M1923, Beretta M1934, Beretta M1935, Beretta M1951, Beretta 70, Beretta 92, Beretta Cheetah, and Beretta M9.
