In R v Hasselwander, Justice Carthy of the Ontario Court of Appeal had to decide whether an uzi was a firearm.

His Lordship seized the opportunity to shine a judicial light the result of which is the edification of students of law everywhere:

"An Uzi submachine-gun is certainly a firearm ....

"The Uzi machine-gun is manufactured in two models, automatic and semi-automatic, the only essential difference being that the semi-automatic, which is the subject of this appeal, has a metal plate spot welded to the trigger mechanism to prevent it from being moved into the automatic position and thus firing bullets in rapid succession during one pressure of the trigger."

The Uzi is made in Israel. According to uzi.com:

"The UZI was developed (and hence its name) by Uziel Gal (1924-2002) a captain in the Israeli army who won an internal competition for the design of a new sub-machine gun. The first prototypes appeared in 1950.... An improved design appeared just before the Sinai Campaign of 1956 and it was in this desert war that the UZI emerged as a winner in the highly demanding surroundings. The UZI turned out to be not only highly reliable, but also surprisingly accurate for such type of weapon, and soon caught the eye of the international firearms community. During the 1960s a new folding metal stock replaced the original wooden stock....

"The UZI's original manufacturer - Israel Military Industries (IMI) - has ... developed a number of variants:- The Mini Uzi is shorter and lighter than the standard model; The Micro Uzi is shorter still, almost the size of a large handgun; Another version is the Uzi Pistol - a semi-automatic version of the Micro."
