There's a free Kedr in the water to the north of the map, near a red wheel sticking out of the water and a circle of rocks. You could also get the Glock that's on top of the tanks at the motor depot (where you got the film) on permovay route. They're significantly better than the Makarov and Tokarev because they hold more than 8 shots.

That mission isn't actually difficult though. Just wait for the one in the Factory main building.
