The .380 ACP (Automatic Colt Pistol) is a popular handgun cartridge developed by John Browning in 1908. It is known for its relatively low recoil, making it a favored choice for self-defense and compact firearms. The cartridge typically fires a bullet weighing between 90 to 100 grains at a velocity of around 900 feet per second. This caliber is commonly used in small, lightweight pistols, which are ideal for concealed carry. While it offers less stopping power compared to larger calibers like the 9mm, the .380 ACP is appreciated for its ease of use and manageable recoil, making it suitable for novice shooters.
