With a proper holster and a good cover garment, the N-frame snubs are no more difficult to conceal over a J-frame, yet offer much better firepower. I personally know of several people who CCW Smith M627 8-shot .357s and you'd never know it if you saw them.
Guys you need to be dressing around the gun. Carrying is meant to be comforting, not comfortable. And remember, two guns is one and one gun is none. Always carry a backup. This new Kimber is set to make for a great BUG but there's no excuse not to carry a more capable revolver.
