I have almost nothing bad to say about this gun.
It fired and cycled without any glitches the first time I took it out to the range. I have had some other guns that had a break-in period. Here there was none: no issues at all with about 150 rounds put through it so far.
It has a very good feel, with obviously precise manufacturing tolerances.
The recoil isn't too bad. The base of my thumb was a little red after 50 rounds, but nothing too unpleasant.
Accuracy is very good especially given the length.
On the negative side: I wish it had better sites (they definitely work well enough though), and I am a little nervous about the small clearance between the slide and my hand. However, it seems to work.
