This topic comes up on a regular basis on this forum, especially with new semi auto gun owners. Mis-feeds causing the extractor to pop out of its track with a FTF.
I solved this problem by lightly staking the extractor with the bolt. I can still remove the extractor by lightly tapping on the rear of it with a punch driving it forward. I have read that Kahr will pin the extractor, and this probably would be a better fix ... As long as the pin/screw doesn't shoot loose and jam the bolt up into the receiver.
All I am saying is this fix worked for me ... I have never had an extractor issue since I did this.
