My Dad described this to me and I flat out didn't believe it. Then I got it in my own hands. Normal (long) takeup, then instead of releasing the striker, it made me squeeze the crap out of it before going Click.
I stripped it down and looked at it. There was some wear on the side of the trigger bar that sticks up out of the grip and acts like a disconnector. Other than a little carbon inside the striker channel, there was no grit, debri or anything out of place.
Without the slide on, the trigger and trigger bar / disconenctor / sear worked perfectly. Put it back together and no bueno. Same impossible trigger pull. I then stripped the slide down - pulled the striker assembly, striker block, extractor, spring & detent. There was nothing amiss there either.
I play with it while the slide is in various states of re-assembly. No barrel or spring, just holding it in place on the frame Now it seems to work in a more normal manner. I get it put together again, and suddenly it's acting like it should. Pull... pull... pull... pulll... click. No more 20+ pounds of pressure needed to get it over that last little bit of travel.
Any ideas what was wrong? I'm stumped. All I did was strip it down a few times, curse mildly as I realized I was missing a pin or spring once or twice, and reassemble it a few times. There is no logical reason why it was malfunctioning or why it is now working properly, and that bugs me.
I am gonna go out on a limb and say there was some sort of debris in the mechanism that you unknowingly removed/cleared via the tear downs and reassemblies. As it seems that the problem is no more, I would say load, shoot, repeat...often. Long time Kahr fan. They have been trouble free for me for many years. Currently own a CM9 and a CW 45. Carry one or both almost every day.

I ran into a similar problem recently with an M&P9. I thought it was a related problem with grit & crud working it's way into the safety plunger in the slide. It was nowhere near as bad as this CW9 was, but it was still really annoying.
Close - same effect but wrong reason. Somehow in a previous cleaning the plunger spring had been bent over. The binding was the plunger having to compress the spring sideways instead of lengthwise.
Lacking a new spring, I was able to straighten it out a little and put it back in upside down so the bent portion is kept straight by the hole in the plunger.

Yup - 100% accurate.
ps - Kahr is still running smoothly.
Make sure the trigger spacer didn't move. You should be able to see the flat side when you look at it
