An investigative report by the Sacramento Bee examined the explosive growth in nail gun injuries, charging that the popular construction tool leads to over 100 emergency room visits daily nationwide. Despite the risks, the guns remain largely unregulated, according to the Sacramento Bee. The firing efficiency of newer nail gun models allows people to work faster, adding to their appeal. They feature a "contact trip" feature, which allows for the automatic firing of the gun whenever it makes contact with a surface. An attorney who won a 2007 $3.4 million jury verdict for a man who was paralyzed after a nail was driven into his brain alleges that nail gun manufacturers routinely set aside money for future lawsuit payouts without altering the guns' designs, prioritizing profits over safety.
