Will it fit? The 6906 and 5906 extractors have different parts numbers on Numrich but is that just due to finish or something minute?

Yes, it will fit. If you buy a new reproduction or new old stock, it is unlikely to work unless you fit & file and make it work. A "quicker" fix (that is unlikely to be the BEST fix...) is to order a used extractor which Numrich also quite often will list available. As I haven't visited in a while, I cannot confirm.

Do ask yourself if you think the extractor is definitely the problem? It is possible that you need a new extractor spring, and if you need that, I would choose Wolff rather than Numrich, because some of the things that Numrich offers are used while all Wolff springs are NEW.

Good luck and report back!
 
Thank you for the help! There's a fellow selling new old stock extractors. I've wanted one as a back-up regardless, but feel that I may need one because when I pull the slide back to do a press check, the round dips down instead of being firmly in place like on most of my other pistols. I can't think of anything else to be causing the issue. I'll probably take the gun and extractor to a gunsmith to have it fitted as well as detail cleaned and will definitely report back!

While I'm thinking about it, though, would anyone have any leads on new barrels or any other parts I should look for to keep the gun running? :)
 
Haha, I think what you SHOULD have done is chosen a junkier gun. Because these 3rd Gens are too darn tough, I just don't think you're gonna need extra backup parts. ;)

That's what everyone keeps telling me! I just happen to be the king of bad luck when it comes to material objects breaking on me. If I own it and it can break, it will. If it can't break, it probably still will.
 
I wouldn't change the extractor unless you are having extraction issues. While having a back up OEM extractor is a good idea, if the gun is functioning properly, I wouldn't arbitrarily change it out.

This extractor is not a "drop in" part and fitting a new one takes special tools including clearance gauges and a pull gauge....and training/experience.

@Mr310 can you please share the seller selling the extractors? I'm looking for one for my 5906 and Numrich is out of Stock
 
Yep, fitting a S&W extractor in the 3rd gen guns requires a factory bar gauge (check the Go/No-Go fit) and a force dial gauge (check the spring tension). The revised extractors have a raised adjustment pad that typically has to be filed to "tighten" the extractor.

They also used to sell a Flag gauge with the Bar gauge to armorers, to also check the case rim clearance underneath the inside of the hook, but that was eventually discovered to be unnecessary if an armorer paid attention when fitting, just using the Bar gauge.

Optional extractor springs are available in lighter and heavier increments to help a tech, armorer or gunsmith adjust the tension in any particular slide so it falls within the desired range (especially in slides made on older equipment, where the tolerances may be "more generous" than in later production guns).

There was also a tension change in the double stack 9's when the breech face was changed from the rounded cuts to the straight cuts (narrow to wide barrel tab).

If it ain't broke, it often doesn't need "fixing".

Checking the ability of an extractor to "hold" a live or dummy round under the extractor isn't something taught to S&W armorers. (This isn't a 1911) Observed functioning (any extraction or feeding problems) and use of the gauges is the recommended method taught to armorers.
