In later production Ruger switched to an E-clip in place of the bolt lock on the safety of the 77, allowing the bolt to be opened with the safety on. An easy swap if you want to change it.
The X bolt has a button on the bolt handle that unlocks it with the safety engaged. So there’s another option for you.
Well if a tanger can be made to lock the safety when unloading I'm sorta perplexed why they are not more common these days.
