Congrats, It's a great pistol. After I bought the first one I had to have a mate for it, so now I have a pair that I rotate practice with. SHoots just about everything I give it, especially the Russian steel case stuff. The only exception is Barnaul, which locks them both up hard, have to disassemble the pistol, remove the extractor, and drive the live round out with a dowel, no bueno. I don't blame that on the guns.
No problems otherwise, just fun to shoot, great triggers, and I shoot them better than Glocks. The 17 and 19 are awfully lonely since I got the CZs.
ETA: I did buy a HBI Theta trigger, but have not felt the need to install it. Although I think I will still play with it at some point.
