I chose the Kahr CW9 after researching a few weeks. One of the things I heard is that it shoots better than most other guns in the class. I haven't verified this yet, as (1) It's been below freezing outside everyday since I've bought it, and (2) I only have 100 rounds of 9mm after buying the last 2 boxes at the shop I bought the gun with. I've gone to 3 other shops and numerous online sites, and everyone's out of 9mm. I paid $399 for it, which I think was a good deal, since Gander wanted $575.
When I was looking at possibilities, my final two were the CW9 and the Ruger LC9. I didn't like the idea of the plastic guide rod on the LC9 after reading about it breaking, plus everything I read, saw, and heard said that the CW9 was a better shooter.
First thoughts on the CW9: I like the size, weight and feel of it. It's nice and comfy. I hardly notice it holstered doing my daily stuff. The slide has grooves cut into it to help when gripping, and these tore my palm up while I was practicing to get the feel of it. I ended up putting gaffer tape over the grooves to minimize this, and now it's just fine. The grip is nice, a good size and feel, but I think I'm going to grind off the little lip on the bottom of the magazine that pokes out into my pinky.
