I posted this question a while back but maybe someone new can give me an answer. I am wondering what year Ruger changed their tang safety. On older m77s the bolt will only open w the tang in the fire position, with my more recent 77s the bolt will open in either the safe or fire position on the tang safety. I am wondering when and why this changed. I prefer the older style myself and info on the year will help with future purchases of m77 tangs. I appreciate any input, thanx Lunker77.
