Using TRUE BLUE Gun Grease on a G17 Gen 3 RTF2 LAV model. Man I must say after running a very intense, wet, muddy ground defense course this past weekend. The Glock ran top. Always racking slickly. Even late in the day with mud all over the gun. It racked excellent never jamming. After the training day I was surprised how little debris or carbon was around. This stuff is excellent and will continue to run and test.
