My bought used M77 Mk1 RSI (tang safety) started acting up the last range trip. This time out it fired when I closed the bolt on a loaded chamber without the trigger being touched. Fortunately the muzzle was downrange so no harm there. A call to Ruger revealed that there is a problem with the trigger overtravel adjustement set screw which is addressed by replacing it. I am surprised that Ruger doesn't want the rifles back to do the fix, especially after the Remington 700 problem, but there you have it.
My rifle experienced both of the problems listed on their notice to Mk1 rifle owners. Fill out the form, mail it to them and they will send you the upgraded part. My card is going in the mail tomorrow.
Don't shoot yours until the fix is made. Mine worked fine until it suddenly didn't.
