I had the CW9 and CW40, the .40 was very uncomfortable to shoot until I put a houge handall jr on it, it was very accurate for suxh a small gun, when I carried it it was hard to remember it was there.
If you are not recoil sensitive like me, you will probably like the CW40. I am in the process of trading of a glock for a P9 because I really regretted getting rid of my kahrs.
