At some point, Custer, you have to decide if the band of Redskins who chased you to the brink of the cliff is more dangerous than would be sliding over the edge, suspended only by a length of 1/4" rope long enough to make the 200 foot rappel to the bottom.
That's kind of how I view the little bit of metal which holds back a fully loaded firing pin. I worry less about hammers or firing pins which can be manually brought brought into action over a live round than a rifle which requires the firing pin to be loaded when a round is chambered.
Sometimes, the air you 'let in'matters less than the air you 'let out'.
