Questions on those who have these. How do your the rails on your lower look? A friend and I looked at his CW9 and he decided to sell it due to the amount of wear on the poly from the slide cycling. Not quite sure how many rounds we put thru it... under 1k if I were to guess. Didn't take pics sadly.
The slide rides on metal rails inside of the frame. I don't have a CW/PM9, but I do have a CW45... rails are fine.
I also have a K9, and it has fired every time. I would try a Kahr before buying something though. I love the trigger for a DAO, and they are very slim for the calibers.
