9mm 380ACP?

Question

i just bought a matching pair of handguns that are pretty sweet, except one is a 9mm and one is a 380 ACP, the magazines seem to be innerchangable but i was curious as to wether or not the 380 could fire off a 9mm round seeing as the 9mm rounds are less expensive, or am i just going to destroy a nice firearm?

Answer 1

The .380 should'nt even be able to chamber a 9mm round. The .380 is also know as the 9mm Kurz,9mm Browning shortand 9mm Corto. You cannot safely interchange ammunition in a semi-auto pistol. Even if the bore is the same diameter its always a bad idea to even think about substiuting a different round then what the pistol is actually chambered for. Use 9mm's in the 9mm and .380 ACP in the 380 ACP

Answer 2

Bound's hubby here:

A 9mm Luger and a .380 ACP fire the same diameter bullet (.355 inches). There are two major differences. The .380 is also called a 9mm short, it is NOT a 9mm Luger. The .380 also fires a lighter weight bullet than the 9mm.

The two rounds are not interchangeable. Both the 9mm and the .380, when chambered, head space on the cartridge mouth (meaning that the case mouth touches the chamber "mouth" and stops the forward movement of the cartridge into the barrel). A .380 ACP will fit into the 9mm chamber, but will not fire because the case head will not remain flush against the slide breech.

As a note: it is rare to hear of a matching pair of handguns that are in different calibers. Is it possible the one you identify as a 9mm is marked either: 9mm Corto, 9mm Kurz, or 9mm Short, and not marked 9mm Luger or 9mm Parabellum?

Good luck!

Answer 3

The 9mm and the .380 are nominally the same diameter. The .38 and .357 are close also. Difference is the .38 can be fired in a handgun rated for .357 since the diameter is the same. A .357, being a magnum round, would ruin a .38 in short order if it did not blow the gun in your hand.

You have the same problem with the 9mm and the .380. although the diameter is not standard throughout the world. The .380, if it did chamber a 9mm (Which is should not since the 9mm is longer.) would probably lose the slide in short order firing 9mm ammo since the 9 has a higher chamber pressure. You could possibly fire .380 ammo through the 9, but accuracy will be in the toilet. It ain't gonna hurt the 9 if it feeds and fires.

It's always best to stick with the ammo the gun is made for except in certain cases like the .357 and the .44 magnums. They will shoot .38 and .44 cal ammo all day and not break a sweat. It's a cheap way to practice with the big ones.

If you get the urge, you could always reload. Size your own bullets and cases. (Actually, you swage a bullet.) But for rounds that small it would not be cost effective unless you shot many rounds a week. But reloading is fun in itself.

Answer 4

A 380 is a kind of shortened version of a 9 mm you can chamber a 380 round in a 9 mm and it will fit but if you put a 9 mm round in a 380 you will see the casing sticks out a little. They are simular but not identical. Use only what those handguns are asking for.

If you like interchangeable ammo get a .357 mag. You can load them with .38 wadcutters for target practice or practical use and save the heavy fire power for a better time

Answer 5

No, don't try it. 380 acp is 2mm shorter than the 9mm cartridge and shaped differently. 380 can feed and fire in some 9mm firearms but does so poorly and with great possibility of damage. 9 mm Marakov is a closer fit, but of no use to you and still not recommended.

If you are looking for a way to fire your pistol on the range for cheap invest in a caliber conversion kit. They are basically a new barrel, slide, and magazine, most commonly in .22 lr, which allows you to shoot hundreds of rounds for the cost of dozens of .380 rounds. And when you'rr done reassemble your pistol as normal for home or self defense.

Answer 6

dont shoot either!!!!!!!! There arent alot, if any, models of pistols that are offered in either .380 or 9mm luger. I would susperc that both are chambered for the .380, but were produced at a different time of at different factories. Does the one that you stated as being 9mm say "9mm luger" "9mm para." "9mm parabellum"or"9x19"?if it does than yes it is your standard 9mm. But remember .380 acp is also known by 9mm, 9mm bwowning short, 9mm kurz, or 9X17. I would really like to know what make/model pistols you are talking about, and would be glad to help you figure it out. feel free to send an email. also do not shoot 380 in a 9mm luger gun, they are NOT interchangeable, and you could really hurt yourself or your guns.

Answer 7

the 380ACP was originally the 380 or 9mm Kurtz. Shorter version of the full size 9mm. You can fire the 380 (not recommended) in the 9mm but not the 9mm in the 380. The more powerful rounded pistol is designed to take the load and weaker calibers of the same diameter. Rule of thumb is not to loose your thumb by being experimental or stoopid! You'll not only destroy the pistol but probably bodily parts as well.

Answer 8

Not so fast Batman!!

Look closely at your 9MM. Does it say 9MM Kurz? or 9MM Corto?

Those are imports and are 9MM shorts. In America they are marketed and sold as .380 ACP.

Answer 9

.380 = 9.652mm
.354 = 9mm

The 9mm is a smaller cartridge. The .380 is the larger.

do the math

caliber to mm -> mulitiply caliber by 25.4
mm to caliber -> divide mm by 25.4

******The caliber or mm of a shell is not always exact is rounded a lot of times!!!!********

Answer 10

you can try to change them out. but make sure your life insurance is payed up. if any gun you have is chambered in one caliber never try a diffrent in it. the only exception is you can shoot 38. in a 357 revolver.
