About
The .380 ACP Ammo is a rimless, straight walled cartridge designed for pistols introduced in the year of 1908. Ever since it was released into the market, it has been very popular in the self-defense department and has been widely used in numerous handguns. The .380 ACP Ammo is considered a misnomer since it doesn't strictly conform to cartridge naming conventions that are named against the bullet's diameter. Using the standard naming process, the .380 ACP Ammo should be named .355 ACP Ammo since it uses a cartridge .355 in diameter. The .380 ACP Ammo, because of its low blow-thrust, delivered a soft recoil to the shooter. The overall length of the .380 ACP Ammo is 25mm, while the bullet diameter measures 9mm. The 45-grain variant of the .380 ACP Ammo can travel at a velocity of 1,835 feet per second while creating an energy level of 337 ft.lbf.Â
