In part 1, next to last last paragraph, it is a Viper SLIVERgun, not a Silvergun. It shoots slivers, not precious metals (although the ammo cost FEELS like buying silver!).

Can't believe I missed it on first read, as one of my players actually pronounces it "Silvergun"!
(I am catching up from a long hiatus from the internet!)
Reading Part 2 next...
