Not a stupid question... but the head of the pin where it fits through the safety lever is much larger in diameter and fits into a corresponding recess.
I'll try tapping it tighter just to see if it breaks the bond, Ruger could have designed a press fit or it could simply be held by a permanent grade of Locktite :{
From what I can make out in the exploded view, the pin body has a small shoulder so it can only go in so far and still give some running clearance to the lever.
I've discovered Brownells carry S-32 pins as a spare part... if all else fails I'll just drill it out and install a new one. Not at all my preference as I like to do things properly!
