This is a video of 'The Greatest Shooter Of All Time' Jerry Miculek highlighting a .45 automatic Glock that was converted to look like a Nintendo Zapper. It's pretty amazing looking. He even plays some real life Duck Hunt with the thing using 8-bit style targets while wearing one of those blow-up Mario riding Yoshi costumes. I was so impressed I'm going to overlook the fact that Yoshi wasn't introduced until Super Mario World on the Super Nintendo.
Keep going for the video.
