Sometimes the solution is so simple it gets overlooked.
With .380 the problems are insufficient expansion with JHP ammo, and overpenetration with FMJ ammo.
Heard it all before...
JHP's are no good for self-defense because they don't expand for whatever reasons, or may fail to feed.
FMJ's are no good for self defense because they can overpenetrate and injure or kill innocent by-standers.
It looks like someone could just take regular .380 FMJ and reduce the powder change to slow it down, and eliminate the dangers of overpenetration. Maybe experiment with heavier bullets too. I see no reason why a slower .380 FMJ couldn't be good alternative. Maybe the ammo manufacturers would be cutting their own throats if they did.
