Uzis are widely available for civilian purchase in a semi-auto version. Several different countries have licensed the Uzi design from IMI in Israel. These countries include China (Norinco), Belgium (FN), U.S.A. (Group Industries), Cuba, and France.
The Uzi Pro is in-use with the Israeli Defense Force which has ordered 8,000 of the new guns to augment existing supply. To-date over 2 million Uzis have been sold to militaries, recreational shooters and everything in between. The standard model is now available, with the braced version to follow. (Photo: IWI-US) In the U.S. the Uzi Pro has been waiting in the works for a couple of years now, with the very first pistols ashore in 2013. IWI-US is happy to announce that the guns are now widely available with prices starting at or under $999.
