The Sa vz. 25 was the second variant of the Czechoslovakian CZ Model 25 series, built and produced around 1948 and 1968, and this variant is better-known than the Sa vz. 23. The variant is acquired with a folding stock. Like the Sa vz. 23, the 25 uses a magazine of 24 or 40 round capacity, and uses the same 9x19 Parabellum ammunition as the latter.

In the RP world, the Sa vz. 25 was adopted by the Mettaurian Federation, and due to is modified and improved structure, it was also adopted by two other factions as a favorited weapon. The "Trotter" variant had been improved to fire more accurately, and because of its lightweight performance, infantry can sustain improved mobility, firing a rate of up to 720 rpm. Magazine can carry up to 37 rounds.

((2022 Update - The 'Trotter' is exclusively being used by the Black Market paramilitary, the Yulruk Regiment, and by an independent African faction known as the Sovereign Defense Front.))
