What do you all think about 9mm vs. .380 ammo?

I have for some reason always liked .380 guns versus 9mm, but that is probably because of James Bond using a PPK and my dad owning a PPK/S as well.



Another topic. Have you seen/heard about the .22 conversion for Ar-15s? With a blackdog 50 round mag?
