O boy, let the media spinning begin.
This is yet one more reason why I give woman a hard time for choosing to carry in their purse. Not to mention the obvious poor access and retention of an article that's not attached to your person, but many woman I have met that carry in this style do not put the pistol in a holster, but just toss it in with all the other brick-n-brack.
Commonly carried are small DA revolvers or small SAO pistols with thumb safeties.
For a SA derringer like this to have gone off, she must have been carrying it hammer back.
For those whom choose to carry in this manner (this goes for back pack carriers too), PLEASE get a proper carry purse/bag that is designed for CC....PLEASE!!!
