Right. But I'm talking about a handgun. I've got books of handguns at home, that I've looked over for years, and unless we're talking about a hand cannon that shoots .454, .500, or bigger calibers (referred to as hunting handguns), no handgun I can think of off the top of my head weighs that much. Most of the 9mm ones I remember weigh somewhere around 1 kg.
And I found the page that talks about the cost of guns in nuyen vs. UCAS dollars. Raygun notes that, while the prices are listed in nuyen, he constructed them with the price as UCAS dollars in mind.
OTOH, you are the GM here. So if you want to say that Raygun's prices are in nuyen, and that I have to pay whatever cost the guns are when converted to UCAS dollars, I'd be willing to go along with that.
EDIT: Just noticed...the guns on Griffin's website are listed in nuyen. So are we gonna have to pay a boosted amount for those, too?
