A .380 is a smaller, lighter, and generally less powerful cartridge and is usually used in small pocket guns. It's .355 of an inch, or approxmiately 9mm, in diameter. A .40 caliber is .40 of an inch, or 10mm, and under normal circumstances, has a higher velocity and more muzzle energy.

∙ 13y agoThe .40 cal has a larger bullet diameter, typically heavier projectiles, and, due to having a larger casing, produces more energy. 9mm variants of pistols can typically hold more rounds in the magazine than the same model of firearm can in .40, however.
