I HAD some but never fired it. I chambered some in my K9 and an unfired round couldn't be ejected by racking. I don't know if it would cycle the slide when fired, either. I hope someone has more info for you. I would definitely make sure that it worked in your pistol and didn't jam it or something.
I'm sorry that I couldn't be more helpful.
