The ejector looks fine-just like the one in my 4506. That one doesn't behave the way this one does in that you will hear a distinct click with the slide closed when inserting the mag and no need to whack the bottom of the mag.

It was very easy to insert the mag with the slide retracted and you could hear/feel the click...not so with the slide forward. I have four mags with the 4516-1 and they all do that.
