The .380 Auto cartridge, also known as 9mm Short or 9x17mm, is a popular choice for concealed carry handguns due to its manageable recoil and relatively small size. Common loadings utilize projectiles ranging from 85 to 100 grains, designed for both target practice and personal protection. Examples include full metal jacket (FMJ) rounds for training and jacketed hollow points (JHP) designed for controlled expansion and increased stopping power in defensive situations.
The compact size of .380 ACP ammunition allows for smaller, lighter firearms that are easily concealed. While less powerful than larger calibers, advancements in bullet technology have improved its effectiveness for self-defense. From its origins in the early 20th century, the cartridge has remained a popular choice for civilian self-protection and has been adopted by some law enforcement and military agencies for use in backup or concealed carry roles.
