I can not and will not say it can't happen, BUT.... Looks to me like it would have to be a sho'nuff mechanical failure like a bent (?) ejector.Being the type I am, I just checked with my Commander and do not see it happening, at least with a 1911 style pistol. 1911's have a slot in the slide for the ejector to ride in, so it would be hard for one to be bent enough to hit the center of the cartridge.
I loaded a single cartridge and with the gun pointed in a safe direction looked into the port while ever so slowly drawing back the slide. The extractor held the case perfectly straight (against the breechface) all the way back until the RIM of the cartridge (at about the 7-ish o'clock position) contacted the tip of the extended ejector.
It might be much easier to happen in another type of semi-auto. I just think it'd be mighty hard in a 1911.
Like I said, I won't say that it is impossible.....heck anything can happen from time to time. YMMV
