The Glock 45 model, in 9mm, is out - got one shoved in my hands the other day. It's the 19X in black. It doesn't have that lip on the front of the grip that the 19X does, so it'll accept all Gen 5 mags, plus all previous versions of mags. It has the Glock plastic sights standard, but you have an option for the same steel night sights that are on the 19X. It's got the 19X cutout on the back of the magwell, but it doesn't come with the lanyard loop. There are no cutouts on the sides or front of the magwell. There are cocking serrations on the front now, that they should have done on the 19X, but didn't for some reason, so that's a big plus. Otherwise, it's a black 19X.
My Gun Pusher, after he shoved it in my hands, was kind enough to tell me that he's got one Blue Label coming in...
Not many picture on the web yet, but here's two:
