Somewhere, somehow, someone posted a "newsman's guide to gun identification" or something like that. It may even have been on this group.
Basically, it had a bunch of long-barrel guns (rifles, assault rifles, shotguns, perhaps even a blunderbus), all labeled as "AK-47", and a bunch of pistols, all labeled as "9mm" (or something).
Anyone got a link? I need it to illustrate a point...
