Extractor rod runout question

[andrew17]

Hey All, I have a question. I have a current model n frame that has some runout on the extractor rod. The gun functions fine it’s just this excessive runout doesn’t lend itself to a consistant trigger pull. The first two or three cycles the trigger pull is slick as a whistle then the next three pulls it seems to bind during the cycle. Not enough to cause a malfunction of any sort but enough that the pull is noticeably harder to cycle.
Spinning the cylinder shows that the extractor rod seems to be slightly off center, but the cylinder itself spins true. Also there’s some shake in the extractor rod itself. Meaning, with the cylinder open, you can wiggle it in the yoke. The rod is screwed in tight but the wiggle and runout is there.
I thought about calling S&W about this but since the gun is functioning, they would probably consider it in spec.
Is straighting / truing the extractor rod a big deal=major surgery?
Suggestions? Comments?

Thanks a bunch

Extractor rod run out

Andrew;

The extractor rod can have a large effect on the felt trigger pull.
I use a Ron Power fixture to bring the TIR down to absolute minimum.
The locking end of the rod is also squared and counter bored to match the angle of the locking plunger and if needed, the angle on the locking plunger is trued and polished. Center pin end clearance is also a factor which effects the free spin. I like at least .003 -.005 clearance.
On open class guns the locking plunger can be eliminated and ball detents used to secure the yoke..

Good Luck

Jerry

An obviously out of alignment ejector rod would not be considered in spec at S&W and they would repair it if you sent it in with a description of the problem.

An out of round rod will cause "hard spots" in the DA trigger pull, and this needs to be repaired, since it puts an unnecessary strain on the action.

While it's possible you could do an acceptable job at home, or get a local gunsmith to do it, I'd prefer letting S&W do it.
They have the knowledge and equipment, and if necessary, new parts.
Unlike trusting locals, S&W is guaranteed to fix it RIGHT, the first time.
