The Zastava M57 is a semi-automatic pistol chambered in 7.62x25mm Tokarev, a variant of the Soviet Tokarev TT33. The M57 is imported to the U.S. by Zastava Arms USA, which is known for bringing high-quality Serbian firearms to the American market​. Notably, it features a longer grip that accommodates a 9-round magazine, compared to the traditional 8 rounds of the TT33, enhancing its usability. The M57 includes several key features such as a half-cock safety, slide lock, and a lanyard loop on both the handgun and magazines. It employs a single-action mechanism with a captured recoil spring and a reticulating guide rod, which allows for easier maintenance. The design of the M57, inspired by the 1911, is distinguished by its more ergonomic grip, which is beneficial given the snappy recoil of the 7.62x25mm cartridge. Surplus models of the M57 are notably affordable, making it a popular choice for those seeking a Tokarev-style pistol with improved handling. The M57A is an upgraded version of the basic M57, featuring an external safety and enhanced polymer grip covers for better ergonomics and reliability, continuing the legacy of precision and durability found in Tokarev designs.
