Beretta M951

The Beretta M1951 is a 9×19mm semi-automatic pistol developed during the late 1940s and early 1950s by Pietro Beretta S.p.A. of Italy. The pistol was produced strictly for military use and was introduced into service with the Italian Armed Forces and other Italian security forces as the Modello 1951 (M1951), replacing the Modello 1934 pistol chambered for the 9×17mm Short (.380 ACP) cartridge.

The M1951 is no longer produced in Italy and was never adopted by the Italian Army. The Italian Army instead opted to keep the .380 ACP Beretta M1934 in service until the adoption of the 9×19mm Beretta 92; the M1951 was instead adopted by the Italian Navy, the Carabinieri and the Italian national Traffic Police but was replaced in all services with the above-mentioned Beretta 92 in 1977.
