As far as a .380 goes, I plan on getting a Ruger LCP as my backup, it is tiny, and pockets quite well. It is also a lot more comfy in my hand than a Kel-Tec, and the Tanfoglio-styled Bersa has a tad too much size to be a pocketable gun. If you are still hell-bent on .380, try one on for size...just my opinion, though...
...Also hoping it might be a gun my wife would be able to handle (the Glock is just a tad too much for her) so she'd be more inclined to hit the range with me.
