I have a S&W 640 and 642 and love both. The 640 is all stainless steel and the 642 is a stainless alloy. I prefer to carry the 642 because of the weight. If you can find one buy it!
I have been trying to find another 642 for 6 months and had no luck. I do not think that there is anyway to lose money on the 642 unless you pay above retail. If you find one and do not want it, let me know.
GOOD LUCK.
