.38 Super

The .38 Super is a pistol cartridge that fires a 0.356-inch-diameter bullet. The Super was introduced in the late 1920s as a higher pressure loading of the .38 ACP or .38 Auto. The old .38 ACP propelled a 130-grain bullet at 1,050 ft/s. The improved .38 Super Auto pushed the same 130-grain bullet at 1,280 ft/s. The .38 Super has gained distinction as the caliber of choice for many top pistol match competitors; it remains one of the dominant calibers in IPSC competition.

The cartridge was designed for use in the M1911 pistol and was capable of penetrating the body armor and automobile bodies of the time. When the .357 Magnum was introduced in 1934, this advantage of the .38 Super was no longer enough to lure police departments and officers from the traditional revolver. The .38 Super retains the original dimensions of the .38 ACP case. The cartridge was originally designed to headspace on the semi-rim, which worked in the Colt M1900 due to the design of the feed ramp. When the .38 Auto became the .38 Super, in the 1911A1, the feed ramp could no longer be used as rim support. As a result of this, observed accuracy of the .38 Super suffered until Irv Stone of Bar-Sto barrels re-designed the chamber to allow headspacing on the case mouth. Since then, all new production .38 Super pistols headspace on the case mouth, as with other cartridges in this class. The semi-rimmed case is known to cause feeding problems in some magazines, especially double stack magazines, and led to the development of new variants with reduced rims (typically only .003" per side).

In 1974 the industry added the +P headstamp to the .38 Super to further distinguish it from the lower-pressure .38 ACP. Most current ammunition manufacturers label ammunition for the Super as .38 Super +P. Since the .38 Super is dimensionally the same as the .38 ACP, an unsafe condition can be caused by firing .38 Super cartridges in a firearm designed for the much lower pressure .38 ACP. The weakness, in the Colt M1900, M1902 and others derived from that design, comes from the assembly wedge at the front of the slide. If the wedge comes out, or the slide cracks at the wedge, the slide can come off the rear of the frame when fired. The 1911 and 1911A1, having a slide that is solid on front, cannot come off the frame that way.

Because of its larger case volume, which allows for more smokeless powder and results in higher muzzle velocities at approximately similar pressure levels, the .38 Super offers higher bullet velocity potential than the 9×19mm Parabellum when handloaded and in some defense loadings. The 9×19mm Parabellum is however approved for higher pressure +P loadings by both SAAMI and C.I.P., which compensates for much of the case volume difference in factory-loaded ammunition. The .38 Super is generally regarded as a well-balanced cartridge with a flat trajectory, good accuracy and relatively high muzzle energy; most loadings have greater muzzle energy than many factory-loaded .45 ACP loadings
