Although I owned a 608, I never used it for concealed carry. It was strictly a range and home defense piece, so I can't tell you what would be a suitable holster. I would hazard to guess a holster meant for an N frame S&W should be okay.
To be able to ccw the 608, in addtion to the above, you would need to have some pretty loose-fitting shirts and a good belt for warm weather months. A jacket would work fine for winter months.
Another thing I'd like to mention about my old 608 is that is was really fond of 158 gr loads. 2" at 25 - 30 yards. 125 gr loads were around 4" or more.
