I just recently completed a 4 Day Defensive Handgun course at Front Sight Firearms Training Institute in Nevada. Before the weekend of training, I took my Citadel 1911 Compact completely apart and applied FrogLube as recommended to all the components. I had only put about 100 rounds through the gun before I applied FrogLube and I figured this 4 Day course would be a great torture test for the FrogLube. I was not dissapointed. The handgun did not have a single malfunction. I completed the course and skills test as a Distinguished Graduate, shot 600 rounds and did not clean my handgun once the entire time! My intent was to run the gun until there was some kind of failure, to test FrogLube… there was NO failure. The handgun is now dirty, but still is running smoothly. I have trained with many other students using 1911s that have had nothing but problems becoming gritty, dry and malfunctioning. FrogLube ran my 1911 smooth the whole time in the hot, dry, dusty Nevada desert for 4 days. Thank you for such a great product!! I will be treating all my firearms with FrogLube and passing the word along to others.
