After reading all these responses, I like this place more and more. I would like to suggest one alternative that I did not remember seeing in any of the responses. Have you considered the airweight j-frames? I see some mentioned the 642. I daily carry a 638-3 in a pocket holster when I am off duty and it rides in an ankle holster when I am working as a BUG to my department issued Glock 19. I have owned scandium revolvers and found that they are just too punishing to even practice with. I have a steel 640 and unless you plan on buying a used older model 38 special only, the new 357 versions are (IMHO) too heavy for every day pocket carry. I would suggest (as some have) the 642, 442, 637 or the 638. I recently added the Crimson Trace LG-405 grips to mine and find that this is just about the best CCW package that I have encountered in the 16 years that I have been carrying guns.
You have been given some good advice by some of the experts and what I have is pretty much .02 cents worth compared to theirs but I thought it was worth mentioning. Whatever you decide I think that everyone would agree that a j-frame is a fine choice.
Regards.
