In GoMo you can get 2x free knives for the extra attack - unlike Necromunda, where the knives cost money - but technically you can only swap ONE weapon before combat. I've always ignored that rule as silly, but if you play RAW then that may be some reason to use a pistol.
Huh, ok then. Btw, do you know how to change usernames? thought the name thing in the registration options page was for your real name...
