I lucked out and found a slightly used stainless CS9 and NIB CS40 and CS45 a few years back, at very good prices. They just didn't sell very well when they were first made. Seems like the best way for S&W to create demand for a product is to stop making it!

I have only shot the CS9 so far. Dead nuts reliable with everything I tried in it. I even bought leather for it, I wish S&W had made them with their regular style of hard plastic stocks instead of the bigger, softer rubber ones they put on them. The Hogues are probably better for shooting but don't help concealment.

Of the 3, I like the CS9 the most. I generally prefer my carry guns in .45 and when I carry a .45 it's usually a Colt Commander. I'm just a cocked-and-locked kind of guy.
