I think a lot depends on where you live. Here in Crossville it's fairly peaceful, low crime rate and it's normally restricted to certain areas. As long as I avoid those bad areas I won't have to worry much about becoming the victim of a crime. Now if we ever move back to Phoenix, AZ you can bet your bottom dollar I'll be packin' something in 40cal with at least a 11+1 round with a couple extra mags to boot. Like I said before, my 642 has been at my side(or inside my waste band,LOL) since I got it last Saturday, my PX4 normally sat in a drawer so which one would serve me better in a gun fight, why the one that I'm able to have with me and that's my little 642, 5 shot. If I've got to face down a gang of criminals then I really don't even think an AR with a 30 round mag would be enough since I'm only one man vs God knows how many criminals in the gang. I've got to be dead on with each and every shot, they've only got to get lucky with a couple shots to get me. I try to plan my life to stay out of such situations if at all possible. I've carried all manner of handguns over the years(starting at age 19 with a Cap n' Ball Remington) and in 31 years I've never needed to use one, I just pray that I never do but if I do I also pray that what I have at the time will be enough to take care of business.
