In my story Half-Breed, at one point the protagonist tells a young gunfighter, "he brought the wrong weapon to a knife fight," since they're standing a foot apart. The older guys watching agree, but the youngster says 'she has it backwards,' (the expression). So, she offers a contest, all he has to do is draw on her and he wins, she'll leave. He can't resist, so draws, but becomes frustrated because she swings her hand forward and he raises the gun into her grip (so, leverage, she now controls it). She says, "just shoot and you'll win." He pulls the trigger--nothing--the web of her hand is between the hammer and the frame. Then she raises her 3" blade knife to his throat.
That's how it really is. They say the vast majority of gunfights happen within 3'. Anywho, sorry for the off-topic.
