Regarding the need for sufficient penetration...
Let's assume 12" is the minimum?
The data I linked to above is (again) for bare gel --which allows an HP bullet to expand freely. Clothing tends to retard expansion, and thus increase the actual penetration. I tend to associate real world COM (or ay other effective) hits with clothing,, so looking at such info is instructive although data with simulated clothing involved can be less available than bare gel performance specs...
Penetration by JHP's through clothing IS generally greater, without crossing the line into great risk of overpenetration. To wit:
Federal's 90gr .380ACP Hydra Shok JHP did
6.70" of penetration 85% expansion in bare gel, and...
12.00" of penetration 38% expansion with simulated clothing involved.
Dennis'
Speer/CCI Gold Dot .380ACP 90gr JHP did
9.30" of penetration 66% expansion in bare gel
11.35" of penetration 38% expansion with simulated clothing involved.

If at least 12" of penetration is what warms your heart, there are plenty of effective JHP's in .380 ACP that fit the bill for ya. That they minimize overpenetration risk to innocent bystanders is no small bonus.
There are certainly exceptions among JHP's.
An odd little fishie is my
Remington Golden Sabre 102gr BJHP
which acording to the manufacturer did
9.70" of penetration 43% expansion in bare gel, but then did
8.8" penetration and 74% expansion with clothing involved.
The extremely-sharp lip of the Golden Sabre probably shears any cloth fragments quickly, and incorporates them into the large mouth-and-hollow just like tissue --aiding expansion and retarding penetration further.

I do have to wonder how we adopt minimum penetration figures, and on what documentary basis. Does it start as one expert's
guarded opinion, repeated by others until it becomes dogma? Not knocking the 11", 12" or deeper penetration crowd. Whatever gives you confidence. I have my preferences, but really don't know if they are the best choices I could make from the many .380 ACP cartridges available.
I'm a brown Filipino, and your U.S. Army, back in the early 1900's --with
practical experience and documentary evidence to stand on-- probably would dismiss anything less than .45 ACP or .38 Special for stopping a determined Filipino civilian assailant --typically 5'3" and 110 lbs, in extremely-light clothing-- before he could hack you and a few others to death. I'm praying that sort of perceived toughness works at least as much for me, as against me
Most public places and streets in my country are just teeming with bystanders.
Houses are cheek to jowl, small and yet serving VERY large families.
Overpenetration is possibly a vastly greater concern for me than it is to you.
Train hard. Fight hard. Save Lives.
