The .38 Super Auto, also known simply as .38 Super, is a semi-automatic pistol cartridge that was introduced in the late 1920s by Colt's Manufacturing Company. It was developed as a higher pressure loading of the .38 ACP cartridge, offering enhanced performance. The .38 Super is known for its high velocity and flat trajectory, which makes it popular in competitive shooting, particularly in disciplines like IPSC (International Practical Shooting Confederation) and USPSA (United States Practical Shooting Association).
The cartridge typically fires a 130-grain bullet at velocities around 1,200-1,400 feet per second, producing significant stopping power and penetration. Its design allows it to function reliably in standard 1911-style pistols with minor modifications.
In terms of use cases, beyond competitive shooting, the .38 Super has seen some application in law enforcement and self-defense due to its powerful performance characteristics. However, it remains less common than other cartridges like the 9mm or .45 ACP in these roles.
Notable attributes of the .38 Super include its compatibility with standard .38 ACP chambers and its ability to achieve high muzzle velocities, making it suitable for tasks requiring superior ballistic performance.
