9mm Ammo Buying Guide
Choosing the right 9mm ammo depends on how you plan to shoot—training, competition, home defense, or suppressed use. While all 9mm Luger (9×19) cartridges share the same dimensions, bullet type, grain weight, pressure level, and case material can significantly affect performance.
Common 9mm Bullet Types
- FMJ (Full Metal Jacket): Best for training and high-volume range use.
- JHP (Jacketed Hollow Point): Expands on impact—ideal for self-defense.
- TMJ/CMJ: Reduced lead exposure—great for indoor ranges.
- +P JHP: Higher pressure loads for defensive performance (use only in +P-rated firearms).

Standard vs. +P 9mm Ammo
Standard pressure 9mm works in all modern pistols and is ideal for routine training. 9mm +P is loaded to higher pressure for increased velocity and improved expansion, but should only be used in firearms specifically rated for +P ammunition.
Brass vs. Steel vs. Aluminum Cases
- Brass: Reloadable, clean, and the most reliable choice.
- Steel: Most affordable; ideal for budget training.
- Aluminum: Lightweight, cost-effective option for casual range use.
Buying 9mm Ammo in Bulk
Bulk 9mm ammo—typically sold in 250-, 500-, or 1,000-round packs—offers the lowest cost per round. It's the best value for high-volume shooters, training classes, and range days.
Understanding bullet type, grain weight, pressure level, and case material will help you choose the best 9mm ammo for your firearm and shooting needs.
