I have NO IDEA....
Just one day she started.
She has tried holster carry in many ways but keeps going back to her purse.
She does admit it is getting more dangerous out there but what the final straw was I don't know.
Took her years after we took the class to finally get her CPL and more years to start carrying.
I pushed at first but have learned, SHE has to decide it's what SHE wants to do.
