I just got this Shield X (first gun) but didn't take it apart until after I put 150 rounds through it. I took it apart to clean it and I'm seeing some yellow stuff on one of its components, I don't know what that rod is but it's the only part in the gun that looks like it has yellow stuff on it. Can someone help me figure out what's going on? Is there something wrong with my new gun or is this normal?
