CCW varies from state to state. A few states don't even require a permit. I grew up in Vermont, where you don't need a permit to carry. Surprisingly enough we also have one of the lowest, if not the lowest homicide rate in the union. I moved down to Virginia last year and it was quite a shock the different view on fire arms. I still got my permit, but it took almost two months of waiting.
Anyways, I carry a Kahr MK9, or a P226 if it's jacket weather. I always keep two extra mags on me and I also pocket a quick assist Gerber pocket knife. I've used that thing more often than any pistol. Opening those stupid plastic cases that every new item seems to come in, impromptu screw driver, etc. etc.
