We have had a problem in our rural neighborhood with a strange man coming in our driveways, turning his lights off, and staying a while. This has happened to myself and 2 other neighbors. I armed my old lady with a CZ 82 with Hornady hp's and I just wanted opinions if this is enough for her. I own several other calibers, however she will not shoot anything stronger than a 9mm Luger. I work late at night often and she is afraid. We do have a good guard dog (Doberman) who attacks also. By the way, the strange man is a judge and lawyer in my county.
