Has anyone tried any kind of moly lube on their firearms? My curiosity arose on the subject at work of all places. We use hydraulic torque wrenches to apply enough torque to twist a Toyota in half (up to 60 thousand ft/lbs) to really big nuts and bolts. I was glancing at my torque specs for different lubricants (API grease, nickel based lubricant, copper based, oil, and moly imbeded grease) and noticed that the moly has a far lesser coefficient of friction than any of the others. For example on a 6.5 inch diameter nut with its 4.25 inch stud lubricated with machine oil my wrench has to produce 33,000 ft/lbs of torque to reach the desired stress on the joint. To reach the same stress on the same stud lubricated with moly grease requires only 13600 ft-lbs. I found that rather impressive.
So yea, anybody tried it? Theoretically it's perfect. Excellent lubricity and tendency to adhere to steel, and in a dry form it won't attract gritty like any oil or grease will. Not that there's anything wrong with oil and grease, but in theory moly would be ideal.
I just applied some 99% pure moly powder to the slide rails, slide stop pin, link and link pin of my 1911. Hopefully this weekend il see how it does.
