What type of 1911---the Colt XSE from your sig line? I had a similar issue that was related to the firing pin block on a Caspian Series 80 slide. You would seem to have a Series 80 pistol...so make sure the firing pin block is not dropping below flush with the bottom of the slide. Also, if anything dinged the back of your frame (like dropping the hammer without the slide in place), it could have raised a burr right about where the edge of the firing pin block channel runs over the frame.

I managed to do the same thing--once--with my G30. The recoil spring had slipped out of place during reassembly. So there, it can happen with Glocks too. Ya'll feel better?

With some 1911's, if the slide release lever/takedown pin is pushed partway out by the trigger finger as the slide moves it will lock up the action and not let it return to battery. If you are racking the slide empty and your index finger is high on the frame above/forward of the trigger guard this may be what happened. You don't have to push the pin too far in to cause this.
It's hard to diagnose over the net. It needs a keen eye to look for binding and proper fit. Take it apart and check it for marks or take it to a smith.
not sure what the heck it was but havent been able to recreate it. thanks for the help folks.
