I would go with the .380 for a lot of reasons not the least of which is stopping power. Also, the prices you mentioned can be bettered. CDNN is advertising the P32 for $199 and the P380 for $214 (P9 for $229 as well).
After FFL fee and shipping, you may end up better off vs. higher price + sales tax.
