Has anyone ever seen this on a Glock OEM "-" connector?
I clean my weapons regularly and this area always has a coating of gun butter on it. The connector has about 5000 rounds on it. I did not know these were plated but it appears so. I noticed this today during a detailed cleaning. I am going to replace it for now. Is it time to toss this one? Thoughts?
Edit: I do not have a spare 3.5 connector so if this one would work until the next one comes in, that would be preferable.
