I got my S&W642 a couple of months back. It is my first firearm and CCW. The people in this forum provided me with a great deal of guidance and advice that was invaluable in preparing me for this - I am most appreciative of you all sharing your knowledge and experiences with me. I've practiced with it at the range about once per week and have gained pretty good control and accuracy with it. I carry it most of the time outside of work and it is a very practical handgun to conceal. I use a SmartCarry, DeSantis Nemesis, and Tucker Cover Up (IWB). It is a simple revolver and I've learned a lot from carrying it and shooting it at the range. I've had a lot of people who shoot semi's at the range ask me about my 642 and they want to shoot it (I warn them that it may have a more stout kick than their semi does).
I recently put a Glock 26 on layaway and plan to have it with me by the end of March. It seems to fit me just as the 642 does.
