Serial number X127053. Made in 1971 with a 4.6-inch round barrel that has a bright bore with strong visible rifling although there is some frosting noted between the grooves. The M57 is a modified & unlicensed derivative of the Soviet TT-33 Tokarev pistol that has longer grip length & therefore greater magazine capacity. It was the standard service pistol of the Yugoslav People’s Army from 1961 until the early 1990s. Condition overall is very good with original factory blued finish across the metallic parts that has oxidized in a few places. Century Arms import mark on the bottom of the trigger guard. Comes with an import compliant safety shoe trigger & an aftermarket 9-round magazine.
