I've seen Jerry Miculuk do 5 plates@25 in 1.8 sec with a revolver from a draw. He practices a lot. The only way to get speed is repetition. Even then your body and your mind set can trip you up. My best was 2.8sec with at Glock 17L. I watched Jerry shoot against his brother Donnie, who could do 2.3's, knock down 5,d unload and holster before his Donnie finished!
