“9mm,” “9mm Luger,” and “9×19 Parabellum” all refer to the same cartridge—the most common defensive handgun caliber in the U.S. thanks to manageable recoil, high capacity, and broad platform support.
Understanding projectile construction helps you choose the right load. The major handgun types you’ll encounter are:
G9 designs are non-expanding, solid-copper projectiles built for repeatable penetration and barrier consistency—without relying on expansion. Expect predictable depth, minimized deflection through common materials, and lighter bullet weights that reduce felt recoil for faster follow-ups.
9mm 80gr External Hollow Point (EHP)  |  9mm +P 80gr EHP
Non-expanding solid with patented exterior geometry for strong performance with or without barriers like auto glass, drywall, and sheet metal while maintaining controlled penetration and quick shot-to-shot recovery.
9mm +P 124gr Woodsman
Deep, straight-line penetration through heavy hide and bone; a non-expanding solid for wilderness defense where large-animal threats exist.
9mm 126gr Subsonic
Tuned for subsonic velocity, stable flight, and consistent terminal behavior with reduced acoustic signature when suppressed.
9mm 115gr FMJ (training ammo) – Clean, consistent practice loads.
9mm 115gr FMJ Projectiles (components) – Bullets only for qualified reloaders; not loaded ammunition.
| Use Case | Load | Bullet Type | Weight | Notes | 
|---|---|---|---|---|
| EDC / Vehicle | EHP / EHP +P | Non-expanding solid (fluted) | 80gr | Reliability; terminal performance controlled penetration; reduced recoil | 
| Backcountry / Hunting | Woodsman +P | Non-expanding, Penetrator | 124gr | Deep, straight penetration through hide and bone | 
| Suppressed / Low-signature | Subsonic | Non-expanding solid (fluted) | 126gr | Similar performance to the EHP, but at subsonic velocities; consistent terminal behavior | 
| Training | FMJ | FMJ | 115gr | Clean, reliable, economical practice | 
| Reloading | FMJ Projectiles | FMJ, Components | 115gr | Components for reloaders; not loaded ammo |
