Armed and Dangerous: A Writer's Guide to Weapons (Howdunit Writing)
"... you will simply have to make your peace with guns. Case closed." No, these are not the words of an NRA apologist attacking some common-sense legislation, rather they're found in the introduction of Michael Newton's authoritative guidebook on guns, bombs, and all manner of things that go "boom"--and alter events in stories.  If you're one of those scribes who believes that killing machines are better left on the printed page, this entry in Writer's Digest's Howdunit series will prove invaluable in giving your Glocks, dum-dum rounds, and spookily-named Hotchkiss guns the unmistakable ring of authority. Bang bang.
