380 ACP

.380 ACP covers ammunition for the 9×17 mm Browning Short cartridge, developed in the early twentieth century for compact semi-automatic pistols. Widely adopted for civilian, police, and discreet carry use, the caliber has seen continuous commercial production and significant variation in projectile design despite its relatively modest dimensions.

This category includes standard ball and FMJ loads, defensive cartridges, specialty and experimental projectiles, blanks, dummies, and manufacturer-specific designs. Variations in bullet construction, case materials, tip treatments, and packaging reflect changing approaches to reliability, terminal performance, and safety in small-frame pistols. The range of examples makes this category particularly useful for collectors interested in early automatic pistol cartridges, concealed-carry ammunition development, and the evolution of modern defensive handgun loads.
