This comparison examines two common handgun cartridges: the .380 Auto and the .38 Special. The .380 Auto, also known as 9mm Short or 9x17mm, is a rimless, straight-walled cartridge often favored for its compact size and suitability for smaller, easily concealed handguns. The .38 Special, also a rimmed, straight-walled cartridge, typically finds use in revolvers and has a longer history of widespread use, particularly in law enforcement.
The choice between these cartridges has been a long-standing debate among firearms enthusiasts and professionals. This discussion arises from their different performance characteristics, impacting factors like recoil, stopping power, and overall suitability for personal defense or other applications. Understanding these differences is crucial for making informed decisions regarding firearm selection for specific needs. The .38 Special, introduced in the late 19th century, quickly gained popularity. The .380 ACP, developed in the early 20th century, later gained traction as a reliable option for smaller, concealable pistols.
