The National Rifle Association benefits handsomely from these relationships. In 2012, for instance, the Austrian pistol maker Glock funneled $115,000 to the group—a donation that isn't reflected in the chart below. Based on available figures, we estimated that nearly half of the group's gun company donations come from foreign manufacturers—the proportion rises substantially if you include donations from Springfield Armory, an American company whose top-selling XD pistol, one of the nation's most popular handguns, is a relabeled Croatian weapon.

Clearly, foreign small-arms makers would not want to export their countries' gun laws across the pond. But would tighter restrictions on gun ownership make us safer? Judge for yourself.

Notes on Methodology

Except where noted, all data reflects the most recent year that figures were available across all countries listed in a given chart or table. The gun death data (per capita rates don't vary a great deal from year to year) and corresponding population data is from 2011 for the United States; 2010 for Austria, Germany, Croatia, and the Czech Republic; 2009 for Italy; and 2006 for Belgium. Since Brazil, Japan, and Canada don't offer comprehensive gun death stats in any given year, the data combines their stats on gun homicides, gun suicides, and accidental gun deaths for years ranging from 1999 to 2009 to reach an estimate of total gun fatality rates. (Population figures for those three countries were taken from the World Bank's 2011 estimate.) The NRA does not disclose precise donation amounts from all of its corporate sources, but it arranges its corporate donors in various tiers depending on their level of giving. For example, Springfield Armory belongs to the NRA's Joe Foss Society, which recognizes members who have donated between $1 million and $4,999,999. The breakdown in the donations pie chart was calculated by assuming that each company's donation fell precisely in the middle of the appropriate range.
