Mad Falcon, 10-4 so do I, I use the Tetra Lub and Tetra grease also on all of the internal, makes cleaning a breese.. That stuff stays on the metal and wards off blow by sticking to the metal.

Update: I forgot to mention, when new, I run my rifle clean with Hoppe's oil and very light lub. Run at least 2500 rounds thru it, then I do a deep clean and Tetra Lub. If you use Tetra Lub before breaking in the rifle, it doesn't have a chance to wear into each other to get that smooth broken in feel we all want and love. I only ran 2000 on the M&P before doing it, since it worked so well out of the box.
