I second Dan's advice. Kahr should make it right. In addition, there are many subtle problems that Kahr will not address which Dan can spot, since he is experienced with the myriad of machining flaws that come with these guns off the line. Knowing where Kahr makes shortcuts is more than half the battle. Mine once broke a firing pin, and Dan identified and internal step which placed a side load on the firing pin as it move forward. After many cycles, fatigue from impact would take its toll and snap off the pin. The rear sight on my rifle was replaced with an original Lyman sight from a WWII lend lease Thompson from Russia, and the screws were abandoned in favor of iron rivets in my shop. Yeah, it's like putting a diamond on a pig, but mine was a project gun, and had as many improvements made to it as the rifle originally cost.
