Typically it will not feed consistently.

Too much extractor "cam out" may be more of a problem, than too much tension: Blocks case head from sliding up breech face during feeding.

My nib 1990 SA [email protected] series 90 sat in the safe for decades because of one stove pipe per mag. It didn’t have a box of ammo through it. I refuse to part with it. I had other 1911’s to shoot that were flawless in operation. After doing my norinco build I remembered my nib SA in the safe growing roots. It took me longer to dig it out than fix it. I tuned the extractor to the browning sight specs. Then set the extractors tention correctly. It operates flawless now. No more stovepiping. I only feed the chamber from the magazine with any auto. Letting the slide/extractor slam shut over a case rim in the chamber can detune the extractor.


When I was researching into my norinco build I purchased the extractor tools from brownells this eliminates the guess work to “is it right or not” failure isn’t an option. Once my extractor tention is set correctly I can count check it off my list.

I would agree that an auto should chamber with the slide, however I always make sure my extractor has room to flex enough to jump the rim. Better than a broken hook. Secondly inertia feeds are an occasional reality, and if the extractor jumps the rim then you will never be bothered as it fired without a stoppage.

I just read this from an article in an article about "Reliability Secrets" of the 1911, having some extractor issues as of late I was wondering about the second part of this statement:
With proper tension, the round should be held in place regardless of how the slide is turned, yet when the round is moved downwards from its center position about 1/10 of an inch, the round should drop off.

The actual movement that allows the round to drop free is variable determined by the case head diameter, extractor cam out dimension and extractor tension. But yes moving the round down on the breachface will cause the round to drop. Physics. What is the absolute dimension to cause this? YMMV

I get your point. I liked the comment as it showed an actual "when" the case "should" drop out rather than the usual "it shouldn't" drop out when just turning and shaking the slide every which way.

I was taught with the empty case captured in the slide by the extractor we can turn the slide 360 degrees and the case won’t drop out. Now with the empty case not dropping out could the extractor be too tight. Having the extractor tools from brownells eliminates this grey area is it set right or not.

Since you have the tools set it for 24oz.-30oz. to pull the gauge/case out.

If we have a 1911 that has feeding problems I like using the correct tools to adjust the extractor so I know it’s set correctly. Then if it’s still not cycling correctly I look at the magazine and ramp next.

That's the tool originally made and sold by Weigand; It does a good job of setting the extractor tension correctly, and (in my experience), a properly tuned extractor will stay that way for thousands & thousands of rounds.

Would this be an adjustment you do to the extractor alone? or do you mod the extractor tunnel as well?

Extractor alone.

I've personally never seen a quality 1911 that needed anything done to the slide tunnel.
In any case, one of pistolsmithings Golden Rules is: "Alter the part that's cheapest/easiest to replace if something goes wrong".

Extractors are dirt cheap compared to a new slide.
