Mike,
I would be very cautious about ANY expanding projectile ammo in the .380 ACP. The laws of physics cannot be changed by any ammo gimmick and this is one place that is fully under those laws. If a lightweight HP (which is all that the .380 offers) expands, it CANNOT penetrate deeply enough to handle an obstructed vital area (12-15" of consistent penetration). Conversely, if a .380 bullet penetrates deeply enough through a threat target, it has not expanded to any significant degree. That's why you consistently see penetration figures of 9-12", which are extremely marginal for any defensive use.
I've found also that the little guns must be thoroughly tested and kept properly clean and lubed. I've noted several cases where they fired the chambered round (usually in off-duty fights) and then failed to feed the next round, usually due to a dry and dirty gun. Some platforms I've seen have routinely failed 100 round function tests with ball ammo, so make double sure yours runs.
If you're going to carry the little gun, I would strongly consider something like the Winchester White Box load with its flat point. At least that flat meplat should create a better crush cavity than a round nose and it will penetrate deep enough to reach the vital area from just about any angle.
