I have the CS45 also. Just can't get out to shoot it as much as I'd like to.
Last shoot was a few months ago. At around 20 Ft I popped off 3 rounds into a circle about the size of a standard door knob - standing without any support. The CS45 is a great CC gun.
Watching some gun shows - I think on Personal Defense - one of the instructors uses the CS45 for his personal defense carry. That's not why I got it but it was nice to know an "expert" felt the same way I did about it....
