There are quite a few to recommend. Here's mine: S&W 640. I had a 642 but it was too much recoil for me. If I carried in the "line of duty," and it had to be revolvers, I would carry a three-inch Smith or Ruger and the 640 as my backup. By the way, I have Crimson laser Grips that will be going on this 640 tonight. Had them on the 642 and sold them with the revolver. Should have kept them.
