Ziadel,
An improperly fitted extractor can snag against the bullet as it is being chambered and is sliding up against the receiver.
In 1911 style pistols, the extractor does not 'snap' over the rim of the cartridge but rather the cartridge is slid up beneath the extractor and any snags or an overly tight-fit can cause a failure to return to battery.
I had the exact same problem and a little time rounding the bottom of the extractor made it go away.
A rough feed ramp generally causes the bullet to stick on the ramp. Bad magazines generally do the same thing. Weak springs and limp wristing usually result in stovepiping. I am generalizing of course, but the extractor does seem to me like the obvious cause. Of course a tight or rough chamber are as you suggested also likely, but messing with a chamber requires a bit more commitment than checking out an extractor.
Oh, and I wasn't expousing the superiority of wilson mags, just suggesting a change of brand to make sure the problem wasn't mag related before he started altering his pistol.
