well,
this is not quite true.
The trigger was and is "User Adjustable" which is a pretty much universal feature nowadays.
The issue was the use of a threadlocking agent inside the trigger that made it vulnerable to sticking, especially after getting heated up, with the result that in at least a few cases, the rifle simply fired when it was put into battery.
That is not an error with people not knowing what they were doing. that is a manufacturing defect resulting in a safety hazard.
They are definitely the most replicated action out there and I own several clones as well as actual 700s. With Tikka mass producing their rifles lately, the balance seems to be shifting though.
