I bought a new Sig C3 in december and had the same issue, I did all the cleaning of the weapon & the mags, plus I bought some Wilson Combat mags for it, still no difference. After about 500rnds I called Sig, and they had me ship in back to the factory. The gunsmith adjusted the extractor, polished the feed ramp, and rereamed the chamber. Now it works perfectly..
I could fix that gun in 30 minutes.
People, 1911's are shipped out rough unless they are over 2K. You should ALWAYS (unless it is an alloy frame) polish the **** out of the feed ramp, and throat/polish the chamber slightly. ALSO, you need to polish the rail in the center of the slide (take slide off, flip over, look toward back, there is a square rail in the center that should be polished). Finally, the breach face should be checked to be smooth, and the inside of the slide just around the locking lug slits (in front of the ejector port) should be smooth, no nasty machine marks.
Finally, make sure you have new mags with powerful springs (i like wolff +5%).
If the extractor is SUPER effing tight it can cause problems, but simply taking the slide and pushing a round up the breach face will allow you to see this.
Use the correct grease on that bad boy and it will feed anything and outperform a GLOCK.
If the gun doesn't work from the factory it's broken IMO and needs to go back. My 1911 has been flawless since I got it new.
