I second this.I have the cw9 and its been flawless. One my frequent carry guns.
I wish I could comment to the two specific guns you've asked about, OP.
But from my own personal experience, I advise folks to stay away from the full-size polymer .40S&W Kahr pistols.
If you like the 9mm and can't find a micro Kahr, there's a used CW-9 in the classifieds for roughly $200 more than it's worth.

Can you expand on your issues with the full size poly .40s?
Can you expand on your issues with the full size poly .40s? I am curious because I own a PM40, and would consider a CW or P40. Lol at the classified post, I saw that and thought it was almost too high for a P9.
