I live in Niagara Falls, Ontario Canada. In February 2022 I was heading to an outdoor match. It was -20º C, snowing and the match was 2 1/2 hours away. 🙁
I get to the match and my pistol would not cycle. I was not happy and thinking what the hell to do. I had a needle bottle of True Blue Gun Oil I had not used yet. So I decided to clean my competition piston of Gun Butter I had been using. After applying the True Blue, my pistol worked flawless the entire damn, cold, match. That experience proved their (True Blue) gun oil worked as they claim. It is now what I apply on all my weapons.
