FWIW, I have been running Weapon Shield on my 1911 and AR for the last several months. So far, it has been living up to my expectations. The Ph.D. level gun guru at for the DOJ recommended it during their recent ballistics lab at Quantico. El Mac knows who I speak of. That carries some weight for me at least. However, at the end of the day, if a guy picks a lube that consistently works for him in the conditions he faces outdoors...then THAT is the best lube for him. Like it's been said before, there are so many good products out there, just decide on one and go with it. Just figured I would share info on Weapon Shield, since it has undergone some torture testing, and a little goes a long way....so not an uneconomical choice.
