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, with a number of 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.
