Thanks. Good point. It doesn’t seem to ride on anything, but I had polished any potential rail surfaces. I have used a red wheel grease , but I do have the lithium using it on my motorcycle ps’ chains.
Will try on the gun.

I found it reasonable to use a heavy lube on slow moving parts of a gun, fill with it blind spring holes/ nests, etc. as long as the gun dust has no way to get there- it seems to perform better than loose oil.
