If some old fart at your club was inclined to discretely place your manual safety on, or to sometimes remove (and hide) the bolt handle on your 391 you'd soon learn not to be distracted by an autosafety.......or any other distraction.

You know this guy - he's the one who tosses an empty in your field of view just before you call "pull". When you miss a target he laughs like the witch in "The Wizard of Oz". Don't tell me you guys don't know this person.

Sadly, our's passed on recently - I really miss him.
