Pistol slide

It is a slide. Guess of what it is :) I think it is finished, though feel free to elaborate if some moves could be made more elegantly. I would do it a bit differently, should I start it now. My biggest concern at the moment is the flaring of the ejection port, it should be all-around, but I managed to get it so far that upper corners are not yet done. I am not too sure in some internal measures - I have no drawings, only a real steel example, sometimes it is hard to measure some things. I think it is within .25 mm on guestimated measures and within .1 in calipered ones. I also added couple of screenshots.
