Design

The .380 ACP cartridge was designed for early blowback pistols which lacked a barrel locking mechanism. The locking mechanism that is found on most other pistols is not necessary for the .380 because of the round's low breech pressure when fired; the guide spring is enough to buffer the energy displaced to the slide. This simplifies manufacture of pistols chambered for such a round, generally thereby lowering the cost. There have, however, been a number of locked breech pistols chambered in .380 ACP. There have also been some diminutive sub-machine guns, such as the Ingram MAC-11. Blowback is a system in which automatic or semi-automatic firearms operate through the energy created by combustion in the chamber and bore acting directly on the bolt face through the cartridge. ...

Performance

The .380 ACP is compact and light, but short ranged and having marginal stopping power. Even so, it remains a popular self defense cartridge for shooters who want a light weight pistol with manageable recoil. It is slightly less powerful than a standard-pressure .38 Special and uses 9mm (.355") bullets. The heaviest bullet that can be safely loaded into the .380 is 115 grains, though the standard has long been 85, 90 or 95 grains. Many consider the .380 ACP to be the minimum cartridge suitable for self defense, while others draw the line at the slightly more powerful .38 Special or at the less powerful .32 ACP.

Ballistic Data

A 6.2 g (96 gr) bullet leaves a 10cm (4-inch) barrel at about 290 m/s (950 ft/s) for a muzzle energy of about 192 foot-pounds (260 joules) of energy.


Notes

  • The .380 ACP should not be confused with the semi-rimmed .38 ACP cartridge which was later developed into the potent .38 Super.
  • Firearms using the round are often marketed specifically to women, with the lighter recoil often mentioned in market material. [1] [2] [3]
