I have been using Weapon shield grease on my Sig P227&MK-25 Navy because their Allow frames and steel slides,also the MK-25 Navy has a real hard bbl. lockup that shows marking on bbl. not wear just marking. I found using the grease really helped in both frame and bbl. it really stays on metal when the metal get hot from shooting, i have found oils will just disappear.
I just wondered if any other forum members were using this brand of grease or other brands of grease's.
