Neither did I, the first go around. Had a giant screwdriver and couldn't get it to move. Heated it up, and it popped right out.
must be a newer event as i have never had any loc-tight on any of the Rugers i own before. however i did just receive a pair of action screws from Ruger the other week for something and i noticed there was a blue bead/drop, very small on the side of the screw near the end that appeared to be blue lock tight. i plan on popping that off before i use the screws.
