Zastava M57

La Zastava M57 es una pistola semiautomática yugoslava y serbia producida por Zastava Arms . Fue la pistola de servicio estándar del Ejército Popular Yugoslavo desde 1961 hasta principios de la década de 1990. ^{[ 3 ]} La M57 era una variante no autorizada de la pistola soviética TT , con varias modificaciones, principalmente una empuñadura más larga y un cargador ligeramente más grande. ^{[ 2 ]} Zastava realizó ingeniería inversa de la TT soviética en 1954 y comenzó la producción en serie de este tipo de arma como la M57 en 1963. ^{[ 3 ]}

A partir de 2021, Zastava todavía producía variantes modernizadas del M57 con características de seguridad actualizadas: el M57A en su calibre original y el M70A en 9 mm Parabellum . ^{[ 5 ]}

Designed in the mid-1950s, the M57 was an unlicensed copy of the Soviet TT-33 Tokarev.^[3] 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.^[3] However, the Tito–Stalin split prompted the Soviet government to cease military aid to Yugoslavia before deliveries of the pistol were fully completed.^[3] In 1952, Zastava was charged with developing its own variant of the TT to satisfy the army's needs.^[4] Zastava's engineers were able to reverse engineer the weapon by 1954, creating a faithful copy of the original TT.^[3] However, its factory was already at capacity manufacturing rifles and submachine guns, and it was unable to open a new production line to produce a new handgun.^[4]

The project was shelved until 1956, when army officials again expressed interest in the TT design.^[3] Work on an improved TT derivative began in earnest in 1957, and the first prototypes appeared in 1960.^[3] The Zastava pistol was formally designated M57 and accepted for service in 1961.^[3] Although the army took delivery of various pre-production models that year, serial production was delayed until 1963.^[3]

Zastava manufactured the M57 for the Yugoslavian state from 1963 until 1982, at which time at least 260,000 had been produced.^[4] It was retired from military service in the former Yugoslavia during the late 1990s and early 2000s, being largely superseded by the Zastava CZ99.^[3]

In 1954, Zastava initially unveiled a handgun that was an identical copy of the original TT-33.^[4] However, between 1957 and 1960, a number of modifications to the Soviet design were made.^[3] 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.^[4] The M57 was also fitted with a magazine safety, reducing the likelihood of an accidental discharge while the magazine is being removed.^[4]

Los ingenieros de Zastava añadieron una mira delantera de cola de milano que se puede ajustar para la deriva, y la parte superior de la corredera del arma está estriada para reducir el deslumbramiento. ^{[ 4 ]} También hubo algunos cambios internos menores, incluyendo un percutor Zastava único y un muelle de retroceso cautivo para simplificar el desmontaje. ^{[ 4 ]}
