Infantry / Small Arms

The Sanna 77 was a short-lived South African submachine gun based upon the framework of the Czech vz. 25 series.

The Czechoslovakian vz. 25 submachine gun, itself based on the Israeli UZI submachine gun, formed the basis of the Rhodesian / South African "Sanna 77". The weapon emerged from design in the 1970s, first in the state of Rhodesia before its serial production was relocated to South Africa, and was trialed by the South African military who found it unreliable enough to pass on the type. Production spanned from 1977 until 1980 and only a limited number were produced before manufacturing ceased.

Production was handled by Dan Pienaar Enterprise Ltd of Johannesburg.

The Sanna 77 weighed 2.8 kilograms and held an overall length of 650mm (450mm with stock collapsed) with a barrel measuring 290mm long. The stock was collapsible which further improved upon the weapon's inherent portability. The magazine, holding 40 rounds of 9x19mm Parabellum cartridges, was inserted into the base of the grip handle as in the UZI. The receiver was cylindrical in appearance and iron sights were fitted over it (forward and rear). The barrel protruded a short distance away from the receiver housing. The trigger group was fitted ahead of the pistol grip in the traditional way.

When compared to the Czech vz. 25, the Sanna 77 had its automatic fire mode removed, restricting the weapon to a more-controllable single-shot function. However, this reduced the tactical value of what was to be a submachine gun and essentially made the Sanna 77 something more akin to an oversized pistol firing through a semi-automatic action. This quality certainly did not lend itself kindly to the gun and, beyond its failure as a military weapon, the Sanna 77 also failed to sell to civilian industry groups (like farmers) as well as police services.

The doomed weapon was finished by the early 1980s.
