A supporter of gun control, Engel has in Congress "worked to ban assault weapons, high-capacity magazines and armor-piercing bullets, institute universal background checks, adopt extreme risk protection orders, and restore funding for gun violence research. " Engel has received an "F" grade from the National Rifle Association and 100 percent ratings from the Coalition to Stop Gun Violence and Brady Campaign to Prevent Gun Violence. He voted against a 2003 bill that immunized firearm manufacturers and dealers from civil liability for gun misuse, supports "smart gun" technology to prevent guns from being used by unauthorized persons, and voted against a bill to reduce the waiting period to purchase a gun at a gun show. In 2009, Engel was one of 53 members of Congress who signed a letter to President Barack Obama, urging the new president to resume enforcement of a ban on the import of foreign assault weapons (authorized by the Gun Control Act of 1968 and enforced during the administrations of George H. W. Bush and Bill Clinton). In 2011, after 400,000 defective gun locks were recalled from the market, Engel introduced a bill intended to protect parents and children from faulty gun locks by instructing the Consumer Product Safety Commission (CPSC) to set a national quality standard for all child safety devices used on firearms.
