Absolutely love mine, I've got the 6" INOX. I don't have a Ruger or a Browning to compare it to, so I'm plumb tickled with it. Shoots exceptionally well, it's actually rated as an introductory target grade pistol, and the accuracy definitely suggests it's capable of such.
Take down is a piece of cake, no tools required for about 95% of disassembly.
3 options in barrel length, if you can find them, (Personally I haven't been able to find the 4 1/2 inch, which I would love to have). And, they make a carbine rifle kit for it, although it's pretty spendy.
Have yet to find any round it doesn't shoot well, and it is one awesome shooting little gun when loaded with Remington Yellow Jackets.
Don't recall ever having had a problem with it of any nature, and I've no doubt abused it. It's performed flawlessly; I've probably put a couple thousand rounds through mine, and I don't think I've ever torn it down and cleaned it but once in the 4 years I've owned it.
