There are two primary variations of 9mm ammo:
- 9mm Luger (aka 9x19mm Parabellum): This is by far the most common type of 9mm ammo you'll find. It's versatile and used in a wide variety of firearms, from compact pistols to submachine guns. You'll find it in both FMJ and JHP configurations, making it suitable for target practice and self-defense.
- 9mm NATO: A higher-pressure variant of the 9mm Luger, specifically designed for military use.
- 9mm NATO: A higher-pressure variant of the 9mm Luger, specifically designed for military use.
- 9mm Makarov (9x18mm): A slightly different cartridge used in some Russian firearms.
Each of these variations is available with several options:
- Full Metal Jacket (FMJ): This is the most common type of bullet used in 9mm Luger ammo. It's reliable, affordable, and good for target shooting and training. It's not the best choice for self-defense though, as it doesn't expand on impact and can overpenetrate.
- Jacketed Hollow Point (JHP): This is the preferred choice for self-defense. It expands on impact, creating a larger wound channel and transferring more energy to the target, increasing the chances of stopping a threat.
- +P (sometimes +P+): These are higher pressure loadings of the 9mm Luger. They offer increased velocity and energy compared to standard pressure rounds, which can be beneficial for self-defense. However, not all firearms are designed to handle the increased pressure, so always check your gun's manual before using +P ammo.
These are the most common types you'll encounter at the range or gun store. While other types exist, they are less common and typically have more specialized uses. As always, remember to choose the right ammo for your specific needs and firearm.
