First, Why don't you hop on over to the INTROS and give us a little background on yourself.
Second, Why would you want to empty your Magazine that way. Why not just remove it and empty it. Maybe I am confused because it is late, but don't believe the Pistol was meant to be used as a unloading machine. Just doesn't sound like a very safe practice.
I will reread the post to see if I understood the question.
I believe you can not rack the slide with the required force to eject the live round, it still has the bullet in the cartridge and the ejector is to eject a spent casing...I could be wrong but others, with alot more knowledge than myself, will let you know.
So I would advise against such practices, my 2 cents, for what it is worth.
