420:. However, SOCIMI/Franchi engineers wanted to distinguish their weapon from the original UZI, by developing a wide array of newer features. The SOCIMI sub-machinegun was built around a solid, monolithic rectangular receiver made out of one single piece of lightweight alloy, departing from the UZI's heavy stamped steel receiver design; the SOCIMI receiver has one single opening on the rear from which the entire bolt assembly can be extracted, while the barrel is inserted in the front and secured by a nut, and can be separated from the receiver by unscrewing it like in the UZI. The grip has finger grooves for better handling. The gun also derives its charging handle being located on top of the receiver from the UZI.

The results of this collaboration were a series of assault rifles, and the Type 821-SMG. The early prototypes and evaluation samples of this sub-machinegun were shortly manufactured directly by Franchi, until SOCIMI had completed tooling-up to start in-house production.

in 1992 and the production of their assault weapons system (including the Type 821-SMG) was halted to be never reprised again. Franchi, owned by SOCIMI until the bankruptcy and undoubtedly the entity behind the development of the SOCIMI weapons system, offered shortly the Type 821-SMG as the "Franchi

The SOCIMI Type 821-SMG is overall lighter and more compact than the
Israeli UZI, weighing 2,450 grams unloaded vs. 3,500 grams of the UZI unloaded; and has an overall length of 400 millimetres with stock folded (vs. 470 millimetres) and 600 millimetres with stock unfolded (same as the UZI). The

The stock is tubular and sidefolding, departing from the complicated retractable design of the
Israeli UZI; it pivots underneath the back side of the receiver and lies flat against the right side of the gun when folded. It is longer than the UZI stock (200 millimetres vs. 180), and results more

of 550 rounds per minute vs. the original 600 rpm of the UZI. Controllability in full-automatic fire results dramatically enhanced. Optimum results are obtained within a range of 150–200 metres, the telescopic bolt balances the weapon such that it can be fired one-handed with complete control.
