When I got my CW45, I thought I'd found the ultimate CCW. It's still my first choice when the size & weight are not an issue (even though it's really small, for a .45ACP). Kinda wanted something a little smaller, though, and just when I'd about resolved to drop the coin for a PM9, they came out with the CM9! Now I've got TWO ultimate CCW's, depending on whether I'm in a situation where toting around the .45 fits (or not).
I carry either one in a High Noon Bare Assets IWB.
