This is one of the more popular videos going around today because the woman points a nail gun towards her and they think she might end up shooting herself with a nail, but I’m pretty darn certain that all nail guns have a safety feature in which the nail will only shoot out when surface contact with the tip of the gun is made.
Depending on you ask the safety is called a tip, lip or tongue and it was definitely in place on that Paslode nailer.
