found the problem.
the ramp on the trigger bar disconnector is mashed down a bit. when the trigger is pulled double action, the trigger bar rides up this ramp, when it reaches a certain point it should allow the the trigger bar to pull free from the sear. since its mashed down, it doesnt allow the trigger to move down far enough to disengage. the trigger bar disconnector is riveted
to the frame.
now, does anyone know a source of cz82 parts?
