i just read ypur other thread and heres a couple of other things.
first i would strongly reconmend not getting a .380 and go for a 9mm.the .380 just wont pack enough take down power.with the right ammo a 9mm will have stopping power.i use a 9mm for every day carry,and right now im using: http://ammunitiontogo.com/catalog1/product_info.php?pName=50rds-9mm-speer-gold-dot-124gr-p-hp-ammo&cName=9mm-hollow-point-ammo gold dot 124g+p hp.these are bonded so they wont break apart when going through hard items like glass,etc,and wont clog up when going through clothes.you can get the bhp's for short barrels.
also dont worry about ammo prices.there is not much difference.both are pretty cheap for target practice form walmart,and get your defence ammo from http://ammunitiontogo.com/
from them you can get twice the amount for half the price(including shipping)and in a +p load
