I have a "hardware" problem in reading fiction. Now in writing it. It has to do with authors, who in their real lives are newbs when it comes to cars, tools or weapons, and they make a blunder during a story. To be fair, it seems to bother most of my gun savvy friends, too. Once the error has been made, the rest of the scene is one blurry fog. I feel I over compensate when writing my own stuff. For example, my lead favors a 10mm pistol. His preference is for a stainless Delta Elite. I had several, nice guns. I had a Bren Ten, but I thought it was too fancy-schmancy for the lead. (I also had one of Colt's Double Eagle tens, showing that even gun designers should take a day off now and then just to rest.) Most of you don't care. But if a writer mentioned a the Elite chambered for .44 AMP, every gun nut would probably put the book down. I'm getting better in overlooking sloppy research in books I read for fun. But as I write, I want to try to get away from "numbers" or automobile minutia or my love of motorcycles. After all, it's the story that is important. I guess every keystroke is acompromise, but I have lots of polishing to do, and I want to make sure I make the correct revisions. Where's the line?
