.380 manufacturing is starting to catch up with demand. It still costs more than 9mm, but prices are coming down. With all the .380s being sold these days they will definitely be increasing production.

As far as concealability, I wonder if you guys have ever handled a Kahr PM9 or Keltec PF9? I have a PM9, and it is hard to imagine needing anything much smaller than that.

Regarding overpenetration of 9mm, are you guys using ball ammo? I don't think a hollow point would go through a body, unless clothing clogged the hollow point so it didn't expand properly.
