Mine shoots really well. I have actually purchased 2 442s in the last year for my wife and I. Both have shot really well and came with the sights regulated perfectly. My bet is that S&W has been making these a long time, so they seem to have the formula down.
When I bought my wife's I took it out to a steel range and was able to knock over rimfire sized turkey's at 50 yards. I was so impressed I just had to get myself one too. It did exactly the same.
I went to the range for a little practice with mine today. At 21 feet it can put a full cylinder into one ragged hole when I'm practiced up. When the bullseye is used up, just shoot another hole in a random place in the paper, try and bisect that hole with the front sight and continue firing bullets into the same place.
I would consider it luck if it had just been one factory specimen, but two different randomly selected specimens having identical performance has at least more statistical significance than a sample of one. haha
Now Im really in the market for a new no-lock 342 with fiberoptic or tritium sights, a 642, and just about any other revolver S&W finally decides to produce without the lock.
