NO!

Don't even think about it. Only shoot ammo for which the gun is designed for, trying anything else can lead to body parts missing or far worse.

Why are you asking?

I'm just gonna say no. I'm not sure as to the exact dimensions of each cartridge, but I'm gonna say no.

P.S. I've seen some guys trying to shoot 45gap out of a 45acp 1911. There's only one different dimension. The gap brass is shorter by a couple tenths of an inch or so. They ended up with a broken extractor on their new shiny S&W 1911. Don't do it.

No

9mm is 9x19mm
.380 is 9x17mm

.357 is designed from the start to accept .38spl. Just as .44spl can be shot from a .44 magnum.

Wouldn't call that an exception as the guns I have seen in that caliber and have read their manuals state very clearly that interchanging 38spl and 357 mag are acceptable. (same goes for .44 mag and .44 special)

HUH???

38 spl and 357 mag isn't an exception to the rule. Pistols chambered for 357 are by default also designed to fire 38spl.

A similar example is shooting 454 Casull AND 45 Colt in a 460 S&W revolver. There are a number of examples similar to this in firearms.

that being said....you can shoot .380 through 9X19 makar. just not the other way around.

i have done it it goes bang no damage happens but the pistol did not autoload the next

so if it were a mad max type scenario and you only had one bullet and a 9mm gun it will fire it

i cant think of any situation why you would want to fire 380 as it is generally more expensive than 9mm

i have also fired 22lr out of a 22 magnum no harm it went bang just expect a split case that may be difficult to remove

so my answer is you can but you shouldn't

Dude, if the box says .380 and the gun says 9mm- I would think that they are not made for each other. That's like putting diesel in a Prius....

HELL YEAH

Dude...DON'T DO IT! If you do...let us know what range you're heading to so we can stay away.

The 380 is a straight walled case, while a 9mm is tapered. The 9mm has a bigger chamber dimension than a 380, plus the 380 is designed as a blow back round so the working pressure for the round is lower than the 9mm.

The rim diameter of the 380 is smaller than the 9mm, but most spring loaded extractor equipped 9mm pistol will hold on to the 380's rim for firing, the lower pressure may not cycle the gun.

No. the barrel can say 9MM Europe but it's a .380 in US if the gun is european.

you CAN but you shouldn't. Like downing a bottle of vodka. You CAN but you shouldn't.
However, in either scenario. If you choose to. Take video and post on youtube.

I've also seen someone put 9mm rounds through a .40sw gun. It didn't cycle reliably and the brass looked like mushrooms afterward. I wouldn't go near there to pick up brass for reloads; and even if I did, I don't think they would go into a re-sizer die.

I fired a few .380acp's in a 9x19 chambered revolver with some success.

From Makarov.com FAQ

Q: Can I fire .380 ACP ammo in my 9x18M Makarov?

A: NO NO NO NO NO !!! There are those that disagree with me including an author of an article in Handguns magazine and gun dealers who wants to sell you a Makarov. The 9x18M cartridge is not a "true" 9mm because it's really 9.2mm. Therefore the bullets are sized .364" and .365" (barrel sizes vary...slugging yours is best to find out your bore size). Yes, you can probably get away with it a few times, but accuracy will suffer, you'll get gas blow-by, your barrel will wear out faster and for what? Save a few pennies? Hardly. 9x18M ammo is usually cheaper since you can get it surplus. If you absolutely want to shoot .380 ACP ammo from your Makarov, then buy a .380 Makarov or a .380 replacement barrel.

For a car analogy, have you ever seen or owned a car that burned oil? How long did the engine last after it started blowing blue smoke? Probably not long. The reason is that the pistons and rings are now smaller than the cylinders and each explosion sends gasses by-passing the piston ("blow-by"). You're literally burning the sides of your pistons now and engine death is imminent. That's basically what you're doing by shooting undersized bullets.

Please don't try this......... Only shoot the caliber that the gun is designed for. Nothing may happen or maybe something will happen. You have to ask yourself "why would I do this"? Would you take a hammer and hit your head with it?

I have never seen anything marked 9mm Europe. Perhaps you mean 9MM Kurtz?

There have been some revolvers chambered to shoot the 9mm auto family (i.e. 9x23, 9x19, 9x17, .38Super,). I handled a 3" Magnaported J-frame chambered in such a manner a few weeks ago, I really should have bought it.

In general, or with a pistol not designed to fire multiple calibers, this is a terrible idea. I doubt .380 through a 9mm would hurt anything, but it won't be accurate, it won't cycle the slide, and I don't think it's cheaper? Just don't do it.

Four words to live by: "Don't Do Stupid S***."

As I understand it, .380 is a 9mm, just not a 9mm Luger. The .380 is 9mm Kurtz. The HK model 4 was made for this round, the 9mm Kurtz, and the .380 ACP works perfectly.
The 9mm Luger round is longer I believe but you can check the size specks at any ammo reseller or at an ammo manufacturers sites.

The gun will fire.
The shooter will survive, and need to manually extract the spent case.
The .380 acp and the 9x19 both use .355 bullets, and a .380 will fit inside a 9mm chamber.

I have also known shooters to load .380 bullets, as light as 90 grains, in 9mm to use for matches.

Accidentally fired a .40S&W in my 10mm Delta one day. No damage, no problem, slide did not cycle fully, primer ruptured and some gas spray back. Can be done in extreme emergency, otherwise NO.

.40S&W can be safely fired in a DA 10mm revolver with the moonclips.

I have done that until I ran row of steel poppers that were lined up in front of each other. I was double and triple tapping each one trying to get them down so I could shoot the next one. I use heavier bullets now. ;) Mark

You would have hammered the poppers down with repeated shots even if you had them loaded to 1500 ft/sec :cool:

But, they were forward falling pepper poppers...
