.380 ACP vs 9mm: Which Is Right for Concealed Carry?
January 12, 2026 · AmmoBin.com
.380 ACP and 9mm are the two dominant concealed-carry chamberings. The real trade-off is gun size and recoil versus power and cost. Here is the practical comparison.
Power vs shootability
9mm is meaningfully more powerful than .380 ACP and is generally preferred for self-defense when capacity and terminal performance matter. .380 is easier to shoot in ultra-small pockets pistols but offers less energy and penetration.
Pistol size
.380 shines in tiny pocket pistols that nearly disappear. Modern micro-9mm pistols have closed much of the size gap, so many carriers now choose 9mm for the extra power in a still-concealable package.
Cost per round
9mm is usually cheaper than .380 despite being more powerful, which makes it cheaper to practice with. Compare live prices for .380 ACP and 9mm Luger.
