When I initially purchased my 642-2 I was looking for a 42 but couldn't seem to track one down. I went with the 642 and eventually put laser grips on it but have since moved away from using them. I spotted a 42 from about 1971 on a local facebook group and offered an even trade and it was accepted. I've got the snubby I've always wanted, hitting the range with it tomorrow. My initial thoughts are how much tighter and smoother everything is on this than on the 642. Its got some holster wear, but its going to get more.
