I’ve used Froglube since 2012 as I switched from using Eezoxx, MD Labs XF-7, and Sentry Solutions grease. As a LE instructor, I have to keep up my training so I attend training regularly and teach twice as much. With my custom AR and Glock 34, I was training in zero degree weather with snow outside, and shot a qual course six times in a row, with a warm up session beforehand. Neither firearm had a hiccup or issue. The temperature had no effect on the parts. Ever since, I’ve used Froglube exclusively on all my firearms, knives, tools, and numerous customers’ firearms. I promote it to shooters all the time. I keep a small container in my range bag to help in classes and for my guns when out and about.
