I agree. I've never been a 'gun-addict', but I usually do my research (primarily for rpg situations). I remember once when I knew about most common weapons (still do) and their corresponding ammunition calibers (which I don't anymore). Things as size, ability, availability, etc would be nice. I'm thinking about going through this again, as I'm once again conducting modern-day firearms research (as opposed to Star Wars weapons - which is much easier, to say the least ) for a character I'm thinking about.
