All shootings: Some 13,286 people were killed in the US by firearms in 2015, according to the Gun Violence Archive, and 26,819 people were injured [those figures exclude suicide]. Those figures are likely to rise by several hundred, once incidents in the final week of the year are counted.
As of December 23, a total of 12,942 people had been killed in the United States in 2015 in a gun homicide, unintentional shooting, or murder/suicide.
Above, from two separate sites. I apologize for being off by 3,000 people; it was not intentional. I'm sure I saw that number in a study somewhere. So, 13,000 people are killed by guns each year in the US, excluding suicide, not 16,000. Call the fucking cops and have me arrested.
