I've always wondered why those manufacturers don't jump in on the profit such products offer.
That's one of my big wonderments too. I went through both the Beretta and Sig Sauer LE Armorers courses with the actual factory reps. Neither one cared one way or the other which lube product was used, but both were quite vocal about using products designed and made for firearms and not products made for the automotive/marine industry. Neither one though very highly of any of the greases either.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
