A friend and I have been discussing the possibilities of two weapon fighting with dagger pistols and a Blink Back Belt. Using Quick Draw and Alchemical Cartridges, you should be able to Shoot-Throw-Shoot-Throw in theory as many times as you get attacks.
Practical? Probably not...
Funny as heck? I can just see my GM staring at me incredulity wondering what the hell I was thinking :D
