I shot my new 629 today and later went to a gun shop and happened to see the Gunsmith... He specializes in S&W wheelguns.

I asked him to look over my 629 and see what he thought. Overall he thought it was a good gun but agreed that the single action pull was funky.

He examined it further and said he believed that despite the transfer bar my gun was exhibiting negative sear engagement.

Has anyone heard of this? And here I thought all I needed was a good trigger job....

What does the term "negative sear engagement" mean? I've never heard that one before. To me, that would mean "no sear engagement". It's kind of hard to diagnose a "funky S/A pull over the internet.

x2 on what is "negative sear engagement"? Sounds like he is trying to sell a trigger job.

That being said, trigger jobs are nice additions to a regular shooter. If he is reputable and his prices is reasonable, get a trigger job......on those two conditions though

Found this...it's in reference to a 1911, but you get the idea.

If your smith thinks your revolver has a transfer bar, you might want to go to a different smith.

Post 4 brings up the same point I would bring up about this "gunsmith" who "specializes in revolvers."

There is not now, nor has there ever been, a "transfer bar" in the Smith & Wesson revolver action of any era, at any time. Period.

You are being "sold a bill of goods." Run as fast as you can and don't let the jack-leg screw up a perfectly good revolver.

If you think you have a problem, send it to S&W.

It refers to the way the sear meets the hammer. There's 3 descriptions: positive, neutral & negative - it tells the amount of metal connects between the 2 parts. Positive means they connect in tightly, neutral means some space or wear & negative means little connection & you could get 'push off'. A push off can be the cause of an AD. This is usually caused by someone doing an action job who has no clue what he's doing. If there's enough good metal left it can be reshaped, if it's past the hard steel it needs replacement parts. If it's a brand new gun it's just the minor flaws in manufacturing & a bit of careful stoning (jigs are available from Brownells or Midway) should fix it right up & you'll have a much more crisp trigger w/ a great release.
