What's the difference between 380 ACP and 380 Auto...

[martybee]

And, don't forget 9mm Corto. The Italians liked that round too!

Other names for .380 include .380 Auto, 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, 9×17mm and 9 mm Browning Court.

I certainly wouldn't do it....

A buddy of mine shot .380 out of my Sig P239 9mm once not paying attention and loading the wrong ammunition into the magazine. He was new to guns at the time. The Sig fed it like a champ, thankfully.

A .45 miss is less effective than a .22 (or .380) put where it counts.

Not really. The flash/bang of a .45 is likely to be more effective at stopping a fight than the sting of a hit with a .22. In the heat of battle, the assailant is unlikely to even know he was hit.

so can you shoot 380 in a 9mm? Like shooting 38 spcl in a 357?

NO! NO! NO!

 

[Florida J Frame]

What difference does it make what you call 380's?

They are not adequate for self defence anyway.

Maybe Erich will pop in here and remind us how many people he has seen on a slab due to the inadequate .380.

And you're welcome.

There's one in every crowd...

Thank you for asking, I didn't know either. Thanks for the education gentlemen.

Even morso than .45acp , a miss with .357 or .44Magnum will stun and awe with muzzleflash and report even better than a 100 Lumen tactical flashlight in the eyes. ( There is sarcasm there , guess which direction .)

Them gadgum furriners sure call all their ctgs funny names. (Humor). But in the USA context , Gun mfg who are not Colt are often loath to mark their products with the name of a competetor , hence .45 Auto , .380 Auto . Goes the other way also with .32 New Police , .38 New Police, and of course .40 Auto .

But the question of .380 in 9mm gun has come up in a serious context. Once upon a time in a nearby county , a miscreant used a 9mm pistol loaded with .380 with felonous intent. His defense included the concept that a 9mm loaded with .380 wasn't really a dealy weapon ( because not go bang , not the stopping power debate ). The expert testimony was that while not always perfect functioning , it would go bang and expell a bullet often enough to constitute ADW .

380 & 9mm are both .355" dia and both headspace off the case mouth so in short, yes.

HOWEVER it may not be powerful enough to cycle the slide in whatever pistol you use so don't expect very good reliability. I would not make a habit of it but it won't hurt the gun at all. I have fired successfully handfuls of 380's thru my M&P 9mm with no problem at all however it was basically a single shot pistol but in a survival situation and for whatever reason you're stuck with a 9mm pistol and a handful of 380's. go for it...

Folks are giving you the straight, if confusing, skinny --- unless you meant the .38 Auto...

 

[MCorps0311]

Thanks,good quesrion? ACP & AUTO.

Hopefully Strat72 wasn't in a survival situation awaiting your answer. You just replied to a thread that is 3.5 years old.

Like Mrs. Gump taught her son, "Stupid is as stupid does."

9mm and 380 both head-space off the mouth, not the rim like a .38 or a .357.

I accidentally fired a 380 FMJ thru a Beretta 92FS I had by accident once. It was lying in a box of 9x19 ball rounds in an indoor range. Just a pop compared to the other rounds and it printed on the target, ejected and fed the next round fine.

I don't recommend it.

 

[TomkinsSP]

Thanks,good quesrion? ACP & AUTO.

TRUTH: Stevens, Smith and Wesson et. al. were not about to roll mark "Colt" on thier products.

THUS: .38 Colt New Police = .38 S&W
.38 Long Colt = .38 Government

 

[Muss Muggins]

So is that yes or no?

Like Mrs. Gump taught her son, "Stupid is as stupid does."

9mm and 380 both head-space off the mouth, not the rim like a .38 or a .357.

To further confuse things...

"ACP", or Automatic Colt Pistol, refers to the firearm. The cartridge is 'Auto'.

Example: the M1911 / Colt Government Model is chambered in .45 ACP. It fires a .45 Auto cartridge.

 

[LoboGunLeather]

Two significant differences:

1. Geography. In the US the cartridge is known as the .380 ACP (Automatic Colt Pistol). In Europe and other continents it is known as 9mm Short (English), 9mm Corto (Spanish, Italian), 9mm Kurtz (German) and more recently as 9X17mm.

2. Market competition. Prior to WW2 many US arms makers developed proprietary cartridges for their rifle and pistol lines. Based upon market demand, many arms makers offered guns chambered for specific cartridges developed by other companies, but they did not wish to provide publicity or advertising to competitors (or be accused of copyright infringement), so they developed common names for the various cartridges. The .44 WCF became commonly known as the .44-40, .30 WCF became the .30-30, .45 ACP became widely known as .45 Auto, the .380 ACP became commonly known as .380 Auto, and a whole range of others. Even our beloved Smith & Wesson offered a semi-auto pistol using the .32 ACP, but marketed it as the .35 S&W.

Confusing? Only at first.

Where do I find them .45 Auto cartridges? All I can find online and at the LGS are .45 ACP cartridges . . .

And they misspelled (mis-abbriviated) Remington as "RIM".
