Green stuff oozing out of PD 627

[Guy B. Meredith]

Well, not quite. However, several times I have found what appears to be the bright blue of copper oxidation seeping out onto the top of the trigger in oil or Hoppe's #9 that had been in the works.

Any idea what this might be? I am not aware of copper internal parts.

Could be the lube the factory applied that's breaking down in the solvent you are using.

Copper fouling in the internals????

 

[Dave Markowitz]

Gun boogers?

Yet another reason to keep your finger out of the trigger guard!

And don't eat the stuff!
