I only use the mobile 1 on my metal guns. Had some malfunctions with my glock when using mobile 1. Not sure if it was the oil, but it happend. Went back to the militec and no malfuntions... Dunno, but mobile stays on the metal guns.
That is odd.. Had to be the ammo, or perhaps limpwristing it.. The only time I've ever had a problem with a glock it was my fault as I limpwristed it.
I originally heard about mobil one from a glock armorer.. been using it for 15 yrs.. O problems..
Yeah Glocks are Polymer but all the contacts are metal.... I don't have enough time using M1 to see the difference in the field.. But just from the first time applying it I was totally impressed with its application.
