Difference between 9mm and 380

In the firearms world, there are a variety of calibers to choose from. The two most popular calibers are the 9mm and the 380. Both of these calibers have their pros and cons, but which one is right for you? In this blog post, we will discuss the difference between 9mm and 380 ammo.

What is 9mm?

9mm is a globally recognized firearms ammunition caliber. 9mm pistols are the most popular handguns in the world because of their affordability, reliability, and ease of use. 9mm ammunition is also used in submachine guns and carbines. The 9mm cartridges are typically loaded with a bullet that weighs between 115 and 147 grains. The 9mm bullet is relatively small in diameter, so it has a high muzzle velocity and is able to penetrate barriers such as Kevlar body armor. Whether you’re looking for self-defense, target practice, or plinking, 9mm is an excellent choice.

What is 380?

380 ammunition is a popular choice for self-defense. 380 ammo is a rimless, straight-walled pistol cartridge that was introduced in 1908. The cartridge was designed by John Browning and is also known as the 380 Auto or 9mm Kurz. 380 ammo is most commonly used in small semi-automatic handguns. The 380 ammunition is a common choice for self-defense because it is powerful enough to stop an attacker but has less recoil than a larger caliber handgun. 380 ammo is also available in hollow point or jacketed hollow point bullets, which expand on impact and cause additional damage to an attacker. If you are looking for a reliable self-defense option, 380 ammunition is an excellent choice.

Difference between 9mm and 380

9mm and 380 are both popular choices for self-defense, but there are some important differences between the two. 9mm is a much larger caliber than 380, so it packs more stopping power. 9mm also has a higher muzzle velocity, meaning that bullets fired from a 9mm handgun will reach their target faster than those fired from a 380.

However, 380 ammunition is generally less expensive than 9mm, and 380 handguns are often smaller and easier to conceal than their 9mm counterparts. So, when choosing between 9mm and 380, it’s important to consider your needs and preferences. If you’re looking for a powerful self-defense option, 9mm is the way to go. But if you’re more concerned with price or convenience, 380 might be the better choice.


In the end, it is up to personal preference which caliber a person chooses to carry. Both the 9mm and .380 offer benefits and drawbacks that must be weighed when making a decision. Hopefully, this article has helped provide some information on the differences between these two calibers so that you can make an informed choice about what is best for you.
