I have one. I also own a Nighthawk T3 and a Colt Talo CCO. So I have some other CCO's to compare it to. It the cheapest of the three, but Springfield brought a nice package to the market at this price.
I was originally going to do some customizing to mine, but after shooting it, I decided to keep it stock. Nice shooting, accurate, reliable.
Acouple of minor things could be better. Like the back of the Extractor should be more even with the back of the slide. The thumb safety could be a bit narrower. I could live without the white dots on the rear sight.
And last having to use a tool to disassemble the guide rod for cleaning.
But all these minor issues are easy fixes if I wanted to fix them.
I think you will be very happy with yours. Springfield has a great package here. Hope they bring it out in 9mm next year.
