The Beretta Model 1918 was a submachine gun that entered service in 1918 with the Italian armed forces. Designed initially as a semi-automatic rifle, the weapon came with an overhead inserted magazine, an unconventional design based on the simplicity of allowing a spent round to be replaced using assistance from gravity. The gun was made from half of a Villar-Perosa aircraft submachine gun,[1] and as such it can be considered the first submachine gun issued to and used by the Italian armed forces, and is possibly the first SMG used as a general-issue combat weapon.

Another variant was the semiautomatic Model 1918/30 with the magazine inserted underneath and came with a bayonet.[2] The Model 1918/30 was also manufactured in Argentina by Hafdasa as the C-1, which formed the basis of the Ballester-Riguard submachine gun.


  • Barrel rifling: 6 grooves with a right hand twist (6-right)
  • Automatic carbine, cal. 9mm, having a barrel length of 12.5" and a magazine capacity of 25 rounds.
