I would agree except I have 3 other guns that work great and a casing gauge that all say otherwise.
On a 1911 extractor, the tension becomes important to both feeding and extraction. If the extractor is too tight the slide return spring is having to fight even harder to feed a round into the chamber because the rim of the round is being squeezed as it slides up the breech face and up under the extractor hook.
Shorter 1911s are already working a little harder with less leverage and momentum for feeding, so they can be more sensitive to this problem. If you are getting sticky extraction though, then you may be right, that there could be a chamber problem. Shorter 1911s can also be a bit more sensitive to chamber fouling and extraction/ejection, because of the stiffer springing that is often used in them.
Troubleshooting a 1911 often involves looking at both sides of the balance in feeding and ejection. Best of luck. If you can't identify the problem, then calling Springfield is another good option.
