Since moving onto our place about 6 months ago my wife has been bugging me about a buyign her a handgun she can use for defense of herself and our livestock from what ever . I have instructed her how to shoot a .22 rifle and she picked right up on it - actually can give me a run for my money for shooting ability. I have only fired a 45 caliber aoutomatic handgun whle n the service. My experience is all with long arms so I need some help here. What is a reliable and easily handled weapon for a woman to use which still has some knock down power behind it? I am looking for caliber, type, and brand advice here. Of course I dont have an unlimited bank account.
