The shortstop is not too far-fetched guys.
I mean, the power of it is, and there are 2 extra barrels, but pistols packing shotgun shells exist. I (read, my father who allows me to use them) actually have one (this isn't it, just a picture of it)

as for the shortstop itself, probably draws inspiration from this type of gun
