Performance
The .380 ACP is compact and light, but has a relatively short range and less stopping power than other modern pistol cartridges. According to gun author Massad Ayoob, "Some experts will say it's barely adequate, and others will say it's barely inadequate." Even so, it remains a popular self-defense cartridge for shooters who want a lightweight pistol with manageable recoil. It is slightly less powerful than a standard-pressure .38 Special and uses 9 mm (.355 in) diameter bullets. The heaviest bullet that can be safely loaded into the .380 ACP is 115 grains (7.5 g), though the standard has long been 85, 90 or 95 grains (5.5, 5.8 or 6.2 g). The .380 has had something of a recent upsurge in popularity with the increase of concealed carry laws, as have the compact and inexpensive pistols that make use of it. Popular pistols chambered in .380 ACP include the SIG Sauer P238, Beretta .380, Walther PPK/S, Bersa Thunder 380, SIG Sauer P230/P232, Kel-Tec P-3AT, Smith & Wesson BODYGUARD 380, Diamondback DB380, Kahr P380, Ruger LCP and Taurus TCP 738. Glock also produces models in .380, though they are not available to the U.S. market because they do not earn enough "points" for importation under Federal law.
The wounding potential of bullets is often characterized in terms of a bullet's expanded diameter, penetration depth, and energy. Bullet energy for .380 ACP loads varies from roughly 190 to 220 ft·lbf. The table below shows common performance parameters for several .380 ACP loads. Bullet weights ranging from 85 to 95 grains are common. Penetration depths from 6.5 inches to 17 inches are available for various applications and risk assessments.
| Manufacturer | Load | Mass (grains) | Velocity (ft/s) | Energy (ft•lbf) | Expansion (inches) | Penetration (inches) | PC (in3) | TSC (in3) |

| Federal | FMJ | 95 | 955 | 193 | 0.36 | 17 | 1.73 | 8.7 |
Key:
- Expansion – expanded bullet diameter (ballistic gelatin).
- Penetration – penetration depth (ballistic gelatin).
- PC – permanent cavity volume (ballistic gelatin, FBI method).
- TSC – temporary stretch cavity volume (ballistic gelatin).

Famous quotes containing the word performance:
“Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.”
—G.C. (Georg Christoph)
“The value of old age depends upon the person who reaches it. To some men of early performance it is useless. To others, who are late to develop, it just enables them to finish the job.”
—Thomas Hardy (1840–1928)
“True balance requires assigning realistic performance expectations to each of our roles. True balance requires us to acknowledge that our performance in some areas is more important than in others. True balance demands that we determine what accomplishments give us honest satisfaction as well as what failures cause us intolerable grief.”
—Melinda M. Marshall (20th century)
