After seeing Mikes comment regarding South Phoenix, I have to chime back in.
I was raised in South Phoenix in the 40's and early 50's when it was still farm/dairy country. I walked all over the place day or night with no fear of any kind except the neighbors Brahama Bull might get loose. I would walk the 8 miles from home to downtown Phoenix to see a movie and then back after hours. Never 1 problem.
Fast Forward to 2008: If I had a dire need such as a child or grandchild stuck down there by some misfortunate circumstance, I would have my M&P40 on one side my GP-100 on the other and a shotgun to my right with extra rounds. I would also attempt to get a friend to ride shotgun with another shotgun.
In that situation mccoy, I would truly feel undergunned with only a 6 shot revolver.
This is not to imply that all residents of South Phoenix are evil but enough are to make me not want to visit my childhood neighborhood.
