After loading, never pull the trigger to lower the hammer. Instead, place your thumb on the hammer spur, pull the hammer slightly past the half-cock position, and then carefully lower it all the way down while keeping the muzzle pointed downrange. For an SA/DA revolver, the hammer should rest on a safe, empty chamber or between chambers if you practice the “six-shooter” carry method.
