The best revolver for concealed carry is the one which you can personally conceal best, which you shoot most accurately, which feels best in your hand, and with which you feel most comfortable. AND which you will be most likely to have IF you ever need it!
The best any of us can do for you is point out our personal favorites for you to try. For example, many people like the Colt Detective Special. I had one and while I found it a good firearm, I personally could not shoot it well enough to feel really comfortable with for concealed carry.
On (in?) the other hand, S&W K-frame revolvers, with the proper grips, are usually good choices for me. Some people like Rugers, some like Taurus', other brands.
You need to find a way to try several different brands and see which seems to fit you best. Then buy one and practise, practise, practise.
Good luck!
