In my opinion, this is one of the best carry guns ever made - but it is not for everyone. The Smith and Wesson 642 "Airweight" is an aluminum and stainless steel J-frame, 5-shot revolver chambered in .38 Special +P. I was surprised to see that the price for these went up by about $100 since I bought mine a few years back. I've owned this gun for a while and carried it a lot, so I figured I do a range report.
