How Do BFAs Work?

I know cops carry snubs as back up guns but I'm talking about service revolvers. Hardly any PDs issue revolvers as the officer's main gun.

And I know moon clips are very fast (I've seen Jerry Miculek shoot), but try loading flat head wad-cutters into a revolver quickly. The flat tips make it as hard to load them as trying to load empty shells in.

SNS is commonly used to define revolvers but autos apparrently enter the class too based on the definitions at urbandictionary.com.
