Firing a 0.356 in diameter bullet, the .38 Super, or .38 Super Automatic, was developed in the late 1920s to be a higher pressure version of the .38 ACP/.38 Auto. Improving on the older .38 ACP style, the .38 Super propelled the same grain weight bullet at 230 ft/s faster. The .38 Super Automatic has earned a place as a caliber of choice for top pistol match competitors.
