Thanks for the responses. I'm planning on carrying a 4" revolver and I do have a few choices with IWB but haven't really made up my mind yet.
Is it much easier to carry OWB while driving? Also, since a revolver plus the holster will be about two inches thick, is it pretty difficult to conceal the OWB bulge? What do you all do about your natural arm placement to the side of your body? I'm also assuming you all are wearing high-rise OWB holsters.
Also, does the revolver barrel bother you any more than say, the thickness of an autoloader?
