Even though the CIP (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives), which was already established in 1912, lists this cartridge under the name 9mm Browning Court (in English: “short”), it's also simply known as 9 mm Short, but internationally as .380 Auto or .380 ACP.

  • Consistent: Uniform penetration, about 10.6”/27 cm on average, over the entire velocity spectrum from 310 to 400 m/s. Very consistent mushrooming of 0.7”/18 mm. Tests have shown consistent penetration and expansion in ballistic gel and Clear Ballistics gel blocks.
  • High stopping power thanks to its 4 "petals": Quick mushrooming with extreme frontal area increase thanks to the four expanding "petals". They guarantee a complete energy transfer with a well-defined wound channel and 100% bullet weight retention.
Shot test in Clear Ballistics block: v0: 390 m/s / 1280 f/s, E0: 418 J /308 ft/lbs – test barrel length: 5.9”/150 mm.
  • Function first: Reliable feeding into the chamber thanks to the rounded bullet nose. Improved ballistic performance with little velocity loss thanks to the bullet's aerodynamic shape. The enclosed bullet construction ensures that no material plugs the hollow point cavity. In this way the bullet retains its expanding properties.
  • All-purpose round: Home Defense – Concealed carry – Hunting
  • Suitable for all barrel lengths: The new cartridge delivers good terminal performance regardless of whether it's used in full-size, compact or sub-compact pistols.
