The .32 ACP (Automatic Colt Pistol) is a small-caliber cartridge designed for semi-automatic pistols. Introduced in 1899 by John Browning, it is known for its relatively low recoil and compact size, making it popular for concealed carry and self-defense. The cartridge typically fires a bullet weighing between 60 to 100 grains at a velocity of around 900 feet per second. This cartridge is commonly used in various handguns, including those made by Beretta, Walther, and Colt. While it is not as powerful as larger calibers, the .32 ACP offers adequate stopping power for close-range encounters, making it a viable option for personal protection.
