Only takes a small torx head screwdriver and a couple of pair of needlenose pliers to fix it or you can order a new spring from Kahr for about $6.
I have 2 Kahrs now and have owned 2 others. They have been exceptionally reliable and accurate but you have to know your way around the idiosyncrasies of the gun.
What he said. If it's been performing perfectly and suddenly started doing what you describe I would look at this first. If you own a Kahr and haven't done so I would encourage you to spend some time on the Kahr Talk site.
Anyway, if you have sent it to Kahr I'm sure they will take care of the problem. They have great customer service.
Out of dozens of handguns I own or have owned my PM9 is my absolute favorite, even over my P226.
