There are over 200 countries/ territories in the world- a list far too long for WikiAnswers. There are varying degrees of restrictions from one country to another of what type of gun, and who can own one. Simply not possible to give a simple answer. Sorry.
Yeah contry have some restriction for it, so it hard to compare.
China and Korea.
Yes, but with restrictions and limitations. And it is Britain.
Usually they buy it from the ammunition shops if they have a gun license. In Africa kids are allowed but some countries don't allow kids to have guns but only adult like U.S.A or Australia.
Clearly ordinary guns have no will of their own, but guns can cause death that is accidental or that results from carelessness.
Not many at all. VERY very few...only some criminals (as all other countries)
The US and the UK are the countries that Nerf guns are sold good so I'd say there is other countries that sell Nerf guns but they definitely sell in Europe.
Yes.
Countries that are members of the UN use guns.
There are a number of countries that do not permit possession of guns by private citizens- Far too many to list. Most tend to be dictatorships that do not trust their own citizens. Other nations may restrict/ limit the guns that can be owned.
I own this app on my iPod and unfortunately you can not customise your own guns
no, guns were developed on their own.
