Can pixies really wield guns and stuff as big as they are?
Due to their size and low Strength scores, pixies are not able to easily use most metahuman-sized weapons. As stated on p.84 of Runner’s Companion, many items of normal equipment may need to be modified for non-metahuman sapient critters, which includes any weapon or item that common sense suggests would be too large for the pixie to wield; a little bit of practical research with a similarly sized doll suggests that anything bigger than a knife or hold-out pistol is unwieldy. As further guidelines, gamemasters may choose to apply the Small Target, Misfit Weapon Size, and Dwarfs and Large Melee Weapons rules (p.161, Arsenal) to pixie characters.
