I had been testing Froglube for several months on most of my guns. The lubrication properties seemed sufficient enough for most of my guns, especially the loose tolerances on my Glocks. However, once I tried it on a match grade 1911 that’s when my problems started to develop. Not only did I have a FTF issue that went away when I went back to my grease lube, but I also had rust develop on the external extractor and the rear sight.
As much as I wanted to like Froglube, I can’t advocate it’s use at this time. For now I will be using my synthetic high temp brake caliper grease on my guns along with some Hoppes oil to keep rust away.
