I have a new 9mm Caracal C QS. 200+ flawless rounds so far. I really like the QS option, at least in good light. Among my other 9mm including MP9c, Walther PPS, PPQ; I would say the Caracal is, so far, better for target acquisition in good light, and better balance and shooter than the S&W MP9C. Love my PPS, Caracal is right there with a better sights and higher capacity mag. I am not sure how the QS system could be modified for low light, but in good light the concept is great. I hope the gun holds up over time, and the gun remains well supported in the US. If you are on the fence, I would say go for it. The QS is great, the quality seems to be there, and the design is produces incredible smooth shooting.
