I'd be glad to!
It's a Sarsilmaz ST-10. Sarsilmaz makes some nice CZ75 clones, and while I was looking at them, this came up. It is, in many ways, an H&K clone mixed with some CZ. Looking at it you can see how much it resembles the USP. Big difference (apart from $500) is that this has an alloy frame rather than the poly. 16+1 9mm capacity, shoots like a dream. I think I have some internals pics around here...

So, it's pretty straightforward. Shoots like a dream, actually conceals very nicely considering its size (full size combat), relatively light... I just really like it. CZ75 mags fit in but don't catch. I suspect that some adjustments to the mag catch would make them fit, feed, and function. They look exactly the same, and when I took it out with my SP-01, I thought that the SP-01 had its first failure in 2000 rounds. Turns out I had just inserted the Sar ST-10 mag by mistake...
