I had a similiar problem with my colt defender 45. it would eject the casing hard to the right around a 4 oclock. they would eject so hard and would, if hit right, stick into the next lanes walls. every so often one would come back and hit my forehead. couple times they would cut me. wierd thing was it worked itself out, after firing a couple hundred rounds thru it. thought i would pass that along.
