    .380/.38 super...

    ...can these two rounds be fired in the same gun?

          The Astra 400 was able to fire many of the 9 mm variations. The two mentioned are some... They mention it is not safe to do it, but then back in the day, they were war weapons.

            The .38ACP and and .38Super are dimensionally the same. HOWEVER, the .38Super should NEVER be fired in a .38ACP pistol. The .38ACP cartridge can safely be fired in a .38Super pistol but may not function. The Super runs at about double the chamber pressure of the ACP. A similar relationship to the .38Spl/.357Mag, but the cartridges remain dimensionally identical.
            Luck favors the prepared.

              I guess that's more what my question was, and thanks for the answer. I have a .38 super and ammo is hard to find, and was wondering if a guy could "plink" with .380acp. I thought the relationship might be as you stated, similar to the .357/.38sp, but it makes sense about the auto loader and pressures.
              Thanks very much.

                  Unless it is held in similar to the 400 Astra... Give correct info guys or don't say a word.

                  Here is the thing about the round's different length...Head space on the case mouth... not going to work well or at all

                    I use 38 Super Auto for IPSC and would not use 380. Much worse than a 22 short in a 22LR chamber. Reloading is the best alternative.

                      I have no intention o using .380 in my Super. Am I correct in understanding the brass is the same between .380ACP and .38 super? Reloading is a matter of charge and OAL?
                      Thanks again.

                          What brand and model 38 super pistol do you have? It is possible to convert many of them to fire 9mmP (9x19) without doing any permanent changes. 9mmP is cheaper than 380. As was mentioned earlier, get into reloading.

                            .38ACP is NOT .380ACP

                            .38ACP (aka .38Auto) ammunition is hard to come by since pistols haven't been specifically chambered for it since before WWII. .38Super has larger superseded it.

                            .380ACP is lower powered/lower pressure/smaller cartridge and remains quite popular due to it being chambered in small pistols.
                            Luck favors the prepared.

                              Also .38 Super is semi rimmed so the extractor would have problems.
