9mm Luger vs .380 ACP: 2026 Comparison
UPDATED 2026ISR 24HEDITORIAL REVIEW
// DIRECT ANSWER
9mm is the better defensive round. .380 ACP serves a specific niche: ultra-compact, pocket-sized firearms where the thinner slide allows for genuinely pocketable carry. In any gun large enough to fit 9mm, choose 9mm — it offers meaningfully better penetration, expansion, and capacity for similar or lower cost. .380 is acceptable for deep concealment when a compact 9mm is not feasible.
| SPEC | 9MM LUGER | .380 ACP |
|---|---|---|
| Bullet Diameter | 9mm (.355") | .355" |
| Typical Grain Weight | 115–147gr | 85–95gr |
| Muzzle Velocity | 1,100–1,300 fps | 900–1,000 fps |
| Avg Cost/Round (FMJ) | $0.22–$0.30 | $0.28–$0.45 |
| Typical Capacity (compact) | 10–15 | 6–10 |
| Recoil | Low–Moderate | Moderate (in tiny guns) |
9mm Luger
- + Significantly better terminal ballistics
- + Lower cost per round
- + Higher magazine capacity
- + More JHP options meeting FBI minimum penetration
- + Wider firearm selection
- − Larger minimum gun size than .380
- − Not suitable for truly pocket-sized pistols
.380 ACP
- + Enables thinner, lighter micro-pistols (Ruger LCP, S&W Bodyguard)
- + Sufficient for close-range defensive use
- + Lower felt recoil in comparable gun sizes
- − Often struggles to meet FBI 12" penetration minimum with standard loads
- − Higher cost per round than 9mm
- − Fewer quality defensive load options
- − Lower capacity than 9mm equivalents
