I have used a Mitch Rosen Clipper for a short period of time, it holds my PM9 tight, and it has VERY comfortable. I decided that I want tuckable so I sold it. If tuckable is not a "must have" in your case, then you should consider it among others... workmanship of Mitch Rosen is top notch.
Heard a lot of good comment on Alessi Talon too, name speaks for top notch quality too, I have their belt-slide.. can't be more happier. I have never tried their Talon (or Talon Plus) myself, but I think KahrShop may have one in stock for CW9.
I'm not a kydex person, and I prefer minimalist holster, so I did not bring up Crossbreed, Comp-tech, etc... lots of good comments everywhere on the web on them being VERY comfortable, I just hadn't used one myself.
good luck shopping.
