Husband and wife are friends of mine. Wife had a recent close call, and wants a 38 special Airweight with laser. She made this choice after talking with other friends and family members. I don't think she would want a 637 with the exposed hammer. Assuming I'm right, it seems the choices are 638 with the bobbed hammer or 642 with internal hammer. She has indicated she might want to carry in her purse once her CHP is finalized, which will be soon. Any opinions? I don't carry or shoot revolvers, so I'm at a loss.
