FMJ (Full Metal Jacket) vs JHP (Jacketed Hollow Point): 2026 Comparison
JHP for defensive carry; FMJ for training. FMJ ammo is designed for target shooting and range training — it is inexpensive, reliable, and produces predictable performance. JHP ammo is engineered for self-defense, designed to expand on impact, create a larger wound channel, and reduce over-penetration risk. Never carry FMJ for self-defense in modern defensive firearms. Use JHP for carry, FMJ for training.
| SPEC | FMJ (FULL METAL JACKET) | JHP (JACKETED HOLLOW POINT) |
|---|---|---|
| Bullet Construction | Lead core, copper/steel jacket | Lead core, hollow tip, bonded jacket |
| Terminal Expansion | None — maintains bullet diameter | Expands to 1.5–2x original diameter |
| Penetration | 18–30" in gel (over-penetrates) | 12–18" in gel (optimal) |
| Avg Cost/Round (9mm) | $0.22–$0.30 | $0.60–$1.00 |
| Best Use | Range training, target shooting | Self-defense carry, home defense |
| Reliability in Carry Guns | Excellent — feeds in any pistol | Excellent in modern pistols |
- + Significantly cheaper — allows more practice
- + Reliable feeding in all firearms including older designs
- + Consistent, predictable performance
- + Wide availability from every manufacturer
- − Over-penetrates — increased risk of collateral damage
- − Does not expand — smaller wound channel
- − Not legal for hunting in many jurisdictions (inhumane)
- + Expands on impact — larger wound channel
- + Reduces over-penetration risk
- + FBI-minimum penetration in quality loads
- + Preferred by law enforcement for duty use
- − 3–4x more expensive than FMJ
- − Can be more finicky in older or budget pistols
- − Some jurisdictions restrict hollow-point carry (NJ, etc.)
