I had a Wyoming arms .45 ACP pistol based very loosely on the 1911. I was underwhelmed by the poor design. When field stripping it the ejector would pop out under spring pressure, and as far as I could see it was designed that way to pop up and eject the spent casing. There was nothing to keep it from popping out and getting lost during field stripping though. There really was nothing to love about the gun compared to any 1911 in my opinion.
