Well, let's be fair here, shall we?
Here's a pic of the Kahr warranty:
Note paragraph 2 that begins with "KAHR ARMS".
ARE you the original owner?
HAS it been more than five years since the pistol was sold?
DID you read the manual booklet - and last page (depicted above) that came with the pistol that spells out in easily understood terms exactly what the warranty is on their handguns?
If not - then it appears your displeasure is misplaced..
