Recently my wife was in downtown Lousiville, she was fallowed by a bum to her car. The man asked for change and when my wife told him she had no cash then the man produced a blade and demanded her purse. She now is in the process of obtaining a ccw permit. I am in the market for a decent, defensive, compact firearm for under $650 in 9mm or .40. Any advise on a rig for her would be greatly appreciated.
