After World War 1, the M-1915/19 was produced; it was basically an M-1915 with the slide cut away from the front sight to the breech face, a feature which later became common in Beretta pistols; the internal mechanism was also changed to give the M-1915/1919 a greatly-improved trigger pull. The entire weapon is also 4mm shorter, yet has a 2mm longer barrel. It is chambered only for .32 ACP. It was made largely for civilian sales, but small numbers were taken into military service as the Model 1922.
