I hope this doesnt explode into a hinge pin lube thread. I hate it when that happens.

That said, Mobile 28 or Mobile One Universal Synthetic grease have worked very well for me. I like the temperature stability, excellent lubricity, and the shelf life is the gold standard. It will still be an excellent lube a decade after you put it in place.

Try that with white lithium grease. I will agree, I wouldnt use the parts store engine assembly lube as a hinge pin lube, BUT, I would rather see and buy a gun that someone had made an effort to use something in that area. Anything beyond Vaseline would be OK in that regard. I dont know why people use Vaseline on guns. But, they do.

I typically use a toothpick to apply it. After use, it is right where I left it, and I clean it off and reapply.

Best,
Ted
