What is wrong with the safety?
1. You need to take it off "safe" to both chamber and unload a round.
2. The position of the safety makes it very easy to catch on brush and get bumped off of "safe". Out west I do not chamber a round until I'm ready to shoot. In Minnesota I do a fair bit of still-hunting, which requires a round to be chambered. On more than one instance, brush has bumped it off of safe while busting through an alder or spruce thicket. Each time it has been immediately caught by myself because I can't go 3 seconds carrying any gun without fingering the safety to make sure it's in the correct position. For a new hunter that doesn't yet have that instinct, it's one factor that could play into an accident.
Honestly, it's my only gripe with the Tikka. For me, it's not a big issue. For my kids or a new hunter, I'm not going to risk it.
