Safety problems make me very nervous.
I would suggest finding a qualified gunsmith who is familiar with Savage 99s, and especially the tang safety version.
I have run across two tang safety guns with safety issues. One was a minor fix, the other was more involved. On both occasions, the above was utilized and I got confidence back in the guns.
