My largest - about bag-purse carry for females is the Texas incident where a woman with a valid CC permit & a loaded .38spl snub left it in her purse then left purse in her vehicle as she ate lunch in a large restaurant.
A spree shooter burst in & shot up the place!
She later became a 2A supporter & a state elected official.
Sidearms should be worn on your person not a briefcase, purse or shoulder-bag.
Extra rounds, gear or a BUG/2nd gun can be toted that way but in a critical event, you need a gun for a gunfight!
