Yes,and so you can observe ,as the slide comes to the rear of its travel,the ejector must protrude enough from the breech face to knock the brass out.
Now,it you load one round in the mag,put the mag in the pistol,drop the slide,and fire,does the slide stay open?
If it does not,it may indicate the slode is not coming fully back.
Are you running it pretty dry,or is it lubed?
Is this a well worn gun,or new?
Arte you holding it relaxed,or with a firm grip?
