Fully Automatic Revolver.

Zen21Tao hits both the problem and the solution.

Could you rig a gas system to drive the trigger of a conventional DA revolver? Sure. But then you have an FA weapon with a capacity of only 6 or 8 rounds, which is absurd, and further is uncontrollable. If you rig up the gun with some kind of belt or a system like the Gatling, it is no longer a revolver which, by definition, contains its cartridges in a cylinder.

For clarification, he's talking about a CAP AND BALL revolver, not modern. I've seen and heard of FA C&B revolvers. Interesting pieces of tech, but very bad for the eyes due to cap debris and hot gasses.
