I've had one (the Glock-style trigger version) for a couple years.
It's been 100% reliable, and has a better stock trigger than any new Glock I've had. Better ergonomics (IMHO) also. It seems at least as accurate as most of my other mid-size polymer pistols.
A couple concerns-the slide stop SEEMS to be plastic, and I've heard reports the locking block is as well; not motivated enough to check my own pistol.
The sights, which are Glock-compatible, are plastic (like a Glock) but have an issue where the dots don't line up with the actual outline of the sights; if you line up the dots, and line up the top of the sights, you'll aim at two different places. Not a huge deal, but annoying.
Also, the finish, while nice, is not any version of nitride or Tennifer; it's just black oxide, as far as I can tell. No problems with mine, but obviously less durable.
I paid about $320 (IIRC) for mine, and they're less now. Based on my example, it's a reliable, accurate and shootable gun; my main concerns are long-term durability, which I haven't (and likely won't ever) be in a position to actually test.
