As far as the semi v. revolver issue, there's certainly nothing wrong with choosing a revolver. Plenty of our members CC revolvers on a daily basis. They do have a lower capacity and fatter profile, but you also don't have to worry about magazines or having a slide pushed out of battery.
How to carry: it depends on your mode of dress. Don't overlook the value of a quality holster and an honest-to-goodness gun belt. Being able to carry comfortably goes a long way to making carrying every day a reality.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
