Your choice in the end
While the final decision on what to carry will be up to you, for what it is worth, I can usually be found carrying a Colt Combat Commander as primary, and two Bersa Thunder .380's as well as a .22 mag derringer as backup. One Bersa is IWB, the other is in an ankle holster, with the .22 in my pocket. I paid $319.00 for my Bersa .380 at Academy Sports, and after over 500 rounds through both, neither had a failure to fire, failure to feed, or failure to eject. My wife also carries two of the Bersa Thunder .380's (one in her purse, the other in an inside-the-bra holster), and refuses to carry anything else. Given that I have four of them, and just invested in Crimson Trace laser grips for all, that alone should speak of how well made I think they are. But again, the choice is yours.
