9mm ammo Vs. 380 Ammo
1. About and History
The 9mm ammunition is designed by Georg Luger and introduced in 1902 by the German arms manufacturer for their Luger semi-automatic pistol.
.380 ACP is developed by firearms designer John Moses Browning and introduced in 1908 by Colt.
The 9mm ammunition is used for NATO and others; The military, police, self-defense, and .380 ammunition are mainly used for self-defense, and some armed forces use them as backup weapons. Both can be excellent defensive calibers if the ammunition is chosen correctly.
Difference Between 9mm and 380
The length of their shells is the most recognizable difference between 9mm and 380. The 9mm Luger is longer than 380, and you can quickly. 9mm Luger has heavier projectiles than the .380 ACP. The 9mm and 380 bullets can fly at the same speed, but the greater mass of the 9mm bullet means it delivers more energy to the target.
Which Is More Powerful?
When you look at the stem, the 9mm unanimously beats the .380 every time. It is a heavier cartridge that produces significantly more energy (including recoil energy) than the .380 ACP. The .380 has less recoil, making it popular with concealed pistols, while the 9mm is more powerful and has more recoil.

Which ammo is cheaper
With the smaller size and simpler construction, .380 pistols are generally cheaper than 9mm guns. .380 ACP cartridges are currently more expensive than 9mm cartridges. This is due to the large supply of 9mm cartridges from various manufacturers and increased ACP ammunition demand. Compare prices of 9mm ammo and 380 ammunition in the USA with those of the national market, and the difference does not exceed 100%, as with others.
Again, that depends a lot on the needs and expectations you have of your pistol. The bottom line is that the .380 ACP round is cheaper to use and more comfortable to handle, while the 9mm round is more potent in all metrics.
