Without searching for it, I remember that there was a fairly simple test you could perform to determine if the factory trigger and safety on your 700 gun was safe or not. I did that test and found that my 700’s trigger/safety was OK, so I left it alone. But that was long ago and I do not remember exactly how the test was done. It is also possible to make a simple modification to the safety so that the bolt can be opened with the safety engaged. The original design was that engaging the safety locked the bolt closed and that was part of the safety problem, i.e., disengaging the safety with the bolt cocked and locked might cause an unintentional discharge if a cartridge was chambered. It was an easy modification, requiring only a Dremel Tool and a cutoff disc. I didn’t do that mod as my trigger passed the test.
