I've been carrying a CW9. It's light,thin and conceals well . Has a light recoil and not "snappish" at all. I keep it cleaned and oiled..runs like a sewing machine. Nary failures to date .. I like it !!
* IF you intend a lot of range time...I'd advise a thin grip cover...'cause the serrations on the back of the grip get a wee bit uncomfortable *
