    9mm short/browning/corto/kurtz are all different names for the .380 ACP cartridge. The loadings are the same, with only the name being different. The same way that 7.65 Browning is the same as .32 ACP and 6.35 Browning is the same as .25 ACP. Browning designed guns for FN in Belgium at the turn of the last century. Since the original guns were made for the European market, they had metric designations. When these designs were built under contract here in the US by Colt, the names of the cartridges were changed to the English system. With the moniker Automatic Colt Pistol (ACP) added on to the end for advertising. So you ended up with different names for the same cartridge in different parts of the world. Many of these names have lingered because old guns marked for them still existed, and people were familiar with the names in their area.

    If you are still unsure, get a 9mm Browning, corto or whatever it is, and compare it to your .380 cartridges. You will see that the case is identical. The bullet shape may vary a bit, but the diameter will be .355-.356".

    It saddens me that even on here there are people who want to see their friends injured. Use only 380 ACP or 380 AUTO, as other "okay" box designations like 9mm Corto are rare enough around here that "box content substitutions" might have happened. It is possible that since you are surrounded by FELON saboteurs, you should also check the case markings! The 9mm Parabellum (Luger) is a bit longer and both shells headspace on the casemouth, so it would take some criminal rechambering your gun to be able to chamber and fire 9mm ammo, but in your case you might have strange enough associates for that to have happened! If it occurred, probably the extractor would hold onto proper 380 Auto shells well enough that the firing pin can fire the primer, so you might not have any clue someone had set you up. IF an EMPTY 9mm case will chamber in your gun, then somebody has set you up this way for a disaster, as the 9mm runs at 35,000 psi and the 380 ACP runs at only 21,500 psi.

    Evidently, one is not an expert. There are two 9mm Browning rounds, the Long and Short. 9mm Browning short is same as .380 ACP.

    Evidently the person who submitted the Wikipedia article didn't know there is a 9mm Browning long. It is in between the .380 and .38 ACP in length and will not interchange with either.

    While in Europe the 380 is also known as the 9mm short or 9mm police, it is not wise to use ammo of an unidentified nature.in short The pressures could throw the slide into your face. There Is a plethora of 9mm the makarov, kurtz, largo, luger, all different and none outlived the 9mm luger. 380 acp only. Unless you feeling wild and have a revolver.

    The 9mm Browning is the same as the .380 acp provided that it is a 9x17mm which is what the .380 acp is. Compare the Browning rounds to a .380 acp side-by-side to be sure.

    9mm Short Ammo

    This depends on what 9mm Browning ammo. There are many Browning pistols chambered for 9mm short. In this country, we call that cartridge the 380.

    Here are a couple of sites that might help.

    No, it won't. That would be dangerous, and it might ruin your gun. So don't try it.

    9mm ammo can only be used for a 9mm gun. You need to use .380 acp for a .380 acp gun. Never try to switch calibers.

    The barrel of a gun was designed for a specific size bullet to go through it. A different caliber wouldn't go through the barrel properly. That means that the gun wouldn't be operating correctly. And that is extremely dangerous, and possibly deadly.

    I have only heard of two times you can use a cartridge not specifically designed for the pistol you are using, the first is most .357 Magnums will fire .38 Specials, the second is sometimes Russian troops would fire 7.63mm Mauser ammo out of their Tokerev pistols that were chambered in 7.62x25mm. I heard the Mauser ammo was a little more powerful, and produced a little more kick. Other than these two instances NEVER fire ammo out of a gun that was not specifically chambered in that round.

    .380acp is also known as 9x17mm. What's commonly known in the US as "9mm" is 9x19mm, 9mm Luger, or 9mm parabellum. There's other handgun cartridges in 9mm caliber, none interchangeable.

    The .380 cartridge was developed by John Browning, so it's possible the ammo you refer to will work, but further information is needed.
