if you pull the slide off the gun, line up the slide next to the frame so that the rear of the 2 pieces are where they should be and look, those rails should engage the groves in the slide by at least a 1/16th". (eyeball, not science).
the people with problems have exchanged serial numbers to see if it was the same production run?
Kahr has to be aware that there is a problem.
My original serial number gun was over 4 years old (SN: SD39XX).
I checked a new CW45 at a local shop and it has the issue. I didn't think to check the serial number at the time. FWIW, the serial on my new frame starts with "SG".
I posted a video earlier to describe the issue, but I've found it's much easier to check for the issue by pinching the slide and dust cover together. Then while holding them together, see if you can move the slide rearward. I couldn't do so on my older serial number CW45 or the one I checked in the store. Post repair: I can easily move the slide with no hint of it stopping or even catching on anything.

Checks good
