1. Short title This Act may be cited as the Gun Safety: Not Sorry Act of 2017 . 2. Findings The Congress finds as follows: (1) There is nearly one mass shooting per day in the United States—355 mass shootings in 2015. (2) In December 2012, a gunman walked into Sandy Hook Elementary School in Newtown, Connecticut, and killed 20 children, 6 adults, and himself. (3) Since December 2012, there have been at least 1,518 mass shootings, with at least 1,715 people killed and 6,089 wounded. (4) On the night of October 1, 2017, a gunman opened fire on a large crowd of concertgoers at the Route 91 Harvest music festival on the Las Vegas Strip, leaving 58 people dead and 527 injured. (5) Every day, on average, 92 Americans are victims of gun violence, resulting in more than 33,000 deaths annually. (6) States with higher gun ownership rates have higher gun murder rates—as much as 114 percent higher than States with lower gun ownership rates. (7) A recent study by the Centers for Disease Control and Prevention looking at 30 years of homicide data found that for every 1 percent increase in a State’s gun ownership rate, there is a nearly 1 percent increase in its firearm homicide rate. (8) Gun death rates are generally lower in States with restrictions such as safe storage requirements or assault weapons bans. (9) Mass shootings stopped by armed civilians in the past 33 years: 0. (10) Because more than 75 percent of the weapons used in mass shootings between 1982 and 2012 were obtained legally, stronger legislation is needed to prevent guns from getting into the wrong hands. 3. 7 -day waiting period required before transferring a semiautomatic firearm, a silencer, armor piercing ammunition, or a large capacity ammunition magazine (a) Transfers by licensed importers, licensed manufacturers, or licensed dealers to persons not so licensed Section 922(t) of title 18, United States Code, is amended— (1) in paragraph (1)— (A) by inserting , armor piercing ammunition, or a large capacity ammunition magazine after firearm the first
