I can't find the thread on the striker foot drag. I think it was on Kahr Talk but it may have been on another forum.

I purchased a CW380 this week and I'm having that issue as well as a few others. I have thoroughly read the threads here and have already done some work on the extractor. The reason I think it's the striker foot or maybe the feeding ramp on the bottom of the side is because with a loaded magazine I can slightly pull the slide out of battery and it will not return. It will return is no magazine is inserted. The thread on the striker foot drag that I did see didn't have a very good description on how where to mod to fix the issue.
