I recently purchased a Kahr CW9 for my wife. After 200 rounds it looked like someone took a file to the recoil pin (Rem and Blazer 115 grain FMJ - nothing special, just cheap ammo). I contacted Kahr and they sent me a new pin/spring. After 200 rounds the new pin looks the same way. Has anyone else had this experience? If so, how was the issue resolved?
