Zastava M57

The Zastava M57 is a Yugoslavian and Serbian semi-automatic pistol produced by Zastava Arms. It was the standard service pistol of the Yugoslav People's Army from 1961 until the early 1990s. The M57 was an unlicensed derivative of the Soviet TT pistol, but incorporated a number of detail modifications, namely a longer grip and a slightly larger magazine. Zastava reverse engineered the Soviet TT in 1954, and began serial production of the weapon type as the M57 in 1963.

As of 2021, Zastava still produced modernized variants of the M57 with updated safety features - the M57A in its original chambering and the M70A in 9mm Parabellum.

History
Designed in the mid-1950s, the M57 was an unlicensed copy of the Soviet TT-33 Tokarev. The Yugoslav People's Army had initially attempted to adopt the TT as its standard service pistol after World War II, and a number were delivered by the Soviet Union. However, the Tito–Stalin split prompted the Soviet government to cease military aid to Yugoslavia before deliveries of the pistol were fully completed. In 1952, Zastava was charged with developing its own variant of the TT to satisfy the army's needs. Zastava's engineers were able to reverse engineer the weapon by 1954. However, its factory was already at capacity manufacturing rifles and submachine guns, and it was unable to open a new production line to produce the TT. The project was shelved until 1956, when army officials again expressed interest in the TT design. Work on an improved TT derivative began in earnest in 1957, and the first prototypes appeared in 1960. The Zastava pistol was formally designated M57 and accepted for service in 1961. Although the army took delivery of various pre-production models that year, serial production was delayed until 1963.

Zastava manufactured the M57 from 1963 until 1982, at which time at least 260,000 had been produced. It was retired from military service in the former Yugoslavia during the late 1990s and early 2000s, being largely superseded by the Zastava CZ99.

Design details
In 1954, Zastava initially unveiled a handgun that was an identical copy of the original TT-33. However, between 1957 and 1960, a number of modifications to the Soviet design were made. The most noticeable difference is that the M57 was designed with a larger magazine that has a capacity of nine rounds as opposed to the TT-33's eight. The M57 was also fitted with a magazine safety, reducing the likelihood of an accidental discharge while the magazine is being removed. Zastava engineers added a dovetailed front sight that may be adjusted for windage, and the top of the weapon's slide is serrated to reduce glare. There were a few minor internal changes as well, including a unique Zastava firing pin and a captive recoil spring to simplify disassembly.
