I do a lot of reading and hate it when the author screws up when he's talking about what guns characters use. The only one who really knows his stuff is Stephen Hunter. I was in Barnes & Noble the other day in the Transportation section looking at a book on the history of Triumph motorcycles when I noticed this book on the next shelf. Writers have no excuse now!
