I assume you are measuring the pull weight with the proper gauge? Even 14 lbs is a little heavy for a 642. On average, they are around 12 to 13 out of the box.
Well, it
is a converted fisherman's scale, not an actual trigger-weight measuring device. I have tested it with known weights (couldn't believe what I was seeing on my Nagant,
) so I'm fairly confident in its accuracy. The 642 ran 17 lbs out of the box and definitely felt like it; there was no way I could fire it with just the pad of the fingertip. I've noticed that there is some rubbing wear from the hammer on the inside of the side plate, and am contemplating doing a little polishing.
You might consider having a reputable gunsmith (such as S&W's Performance Center) do an action job on it.
I really hate leaving my gun with a gunsmith. I went through some separation anxiety when I had the sights put on my 1911.
Been thinking about getting a 442 to go with the 642-- if I do, then leaving the latter with someone wouldn't be as painful, since I'd have the same-format gun to carry.

Thank you for the coin test. I'm going to give that some practice time.
By trimming everything down to just the action of trigger finger and palm, you can easily see where the deviations from aim creep in. The lightness of the gun will result in a little hop of the coin when the hammer falls, but if everything is steady, it won't fall off. I hope it does you some good; it certainly has for me.

Gunscrubber!! I have heard this can totally dissolve the clearcoat on 642s.
No problems here. I was only spraying it into the action, though, and any splash-over would have evaporated pretty quickly. I note that the label does warn about possible damage to plastics-- gonna have to be careful I guess. I do use it on my P32, though, without any visible damage.
