I have noticed that if the slide is locked open on my 9mm Shield, if I put in a loaded magazine, the top bullet(round) makes contact with the ejector. However, if I load the gun with the slide closed, it does not make contact with the ejector. I'm used to firing my weapon and when the last round is fired, placing another loaded magazine in while the slide is still locked back. This is the fastest way to re-load. It seems this will damage the ejector.
