Because Ruger claimed their guarantee was void, I’m making the same guess: Somebody tried to “adjust” the trigger too lightly or replaced it with an aftermarket trigger that was adjusted too lightly. I hunt a lot with Ruger No. 1s and have owned a bunch in calibers from .220 Swift to .375 H&H.; I do my own trigger work but don’t try to reduce the pull below 3 pounds, and I have never had the slightest problem, despite shooting some of them far beyond 500 rounds. Go ahead and buy your No. 1, but if the trigger isn’t satisfactory, take it to a competent gunsmith and have it adjusted to no less than 3 pounds.
