I've always been partial to the Remington Roomsweeper. Point, shoot, instant red mist. Just don't play an elven decker (er, sorry, it's hacker nowadays, isn't it?) with a BOD and STR of 1 and a listed weight of 98 lbs. when you use it.
Poor Sparky went right over the rail after a particularly bad roll. Off the top of a Seattle high-rise. According to the GM, Sparky's death prompted more than one unfortunate cabby to go vegetarian.
