When I ordered the guide rod and I had also ordered the Fiber Optic sight. When they arrived, Kahr had sent the WRONG guiderod. It was marked correctly on the invoice, but the package was incorrect. It was about 3/8" too short. I returned it and when the new one arrived, made sure it was correct.

Before going to the range next I will do a complete cleaning and lube it all well. I do have about 2,00 rounds now and would not expect the spring to need replacing yet.
