Head to Head
.380 ACP vs 9mm
Pocket-pistol convenience vs. real-world stopping power.
.380 ACP
Best for: Deep concealment
- Tiny, light pistols
- Easier to pocket carry
- Less recoil in micro guns
- Better than nothing always
VS
9mm
Best for: Primary carry
- Meaningfully better terminal performance
- Micro-9s now nearly .380 size
- Cheaper ammo
- Higher capacity in similar frames
The Verdict
Modern micro-9s (Hellcat, P365) give you 9mm performance in nearly .380 size — most people should carry 9mm. Reserve .380 for the smallest pocket guns.
