Guns Around the World
Gizmodo came up with a list of the most popular guns in each region of the world. Then they made it even more interesting by color coding and placing them on a map of the world where they are most common. However, this is just the most common weapons in that country/region, but as you would expect, the military, in most countries have the majority of firearms. So this map isn't exclusive to personal ownership or solely military, but rather both.
