Lead won't penetrate your skin - BUT

.....

Dad, if I don't caution him, instinctively picks up guns with his finger on the trigger because that's how he grew up. Military training, etc. 

....

This just grated on me and I finally could not refrain from comment... Picking up a firearm with your finger on the trigger was never encouraged in any military training or in any military practice in the United States. It is just plain bad gun handling. Has nothing and I mean nothing to do with military weapons training.
