380 in 9mm?

Can I shoot 380 ammo(9mm short) in a S&W 940 or 986 safely? Also have an older S&W 9mm that doesn't use moon clips and would like to know if anyone has tried to use 380 in it. Thanks!

I would think that if your pistol used some sort of half/full moon clips 380 would work, as you need something to headspace the shorter cartridge on. Sort of a 38 Special in a 357 Mag.
Added yep there is 0.005 difference in the rim thickness and almost .020 in the case diameter. So they might not fit or go off and if they do they could split.
How successful it actually was, is questionable though? It came and went on the market very quickly.
Here is a photo I got off the net. Of one and the different cartridges it supposedly fired. The only way I could envision that it worked, was that the chambers were over sized. And it had individual spring loaded extractors, that held the base of the cartridge against the face of the breech.

not a good idea, the .380 has a smaller case dia. than a 9x19mm = case splits or blow back.

Line up a row of about ten 9mm rounds on their sides (side to side) and do the same with .380 rounds. When you see the "curve" forming with the 9mm rounds, while the .380 rounds line up "straight," you'll understand that while the .380 is called (more in other parts of the world than the U.S.) "9mm short" it is NOT built from just a shortened 9mm case.
The only objective review of the Medusa that I saw said that it was NOT reliable with .380.
Then there is the risk of the undersize case rupturing.
Don't do it.
.380 is so much smaller head diameter that it will likely fall out of a 9mm P clip. I don't know if the "umbrella" extractor in a 547 will engage the rim or not.

This bug a boo about a undersized case rupturing, is more theoretical, ( old wives tale ), then realistic. In my personal experience.
At various times in the distant past. I have shot 357 Sig, in 40 S & W. And .380, in 9mm Makarov. With the only negative result of bulged unreloadable brass cases. No damage to either the pistol(s), or the shooter.
In an emergency, I'd give it a whirl. There's many other combinations (.308 in 30-06, 16ga in a 12ga) that will work but are considered bad manners by the black and white people.
Improvision is sometimes the difference between life and death. Have the knowledge to know what's possible and what isn't is also a plus.
