Already one NPC in my group has one... Mi Chan, the Korean Rickshaw Driver based out of Junkyard.
I don't know weither he can handle the recoil or not, and, frankly, neither does he. He only needs to pull the bloody thing out, and everyone runs in terror!!!
Good thing, too... He only has one bullet. ;-)
Hey, if he was rich, he would have a cab, not a rickshaw!!!
Ray.
PS: If you want to use him, fine. He charges $20 Widgets a day, more for heavy loads (Due to cargo or heavy people), and when you eat, so does he, on your tab! He knows almost every area of Junkyard, and quite a few of the Informants and Slimy Underbelly (For the Slimy Upperbelly, you gotta check out other areas... Maybe a Limo Dealership or something...).
