Mas has been around a long time and contributed a lot to training and shooting techniques. As I understand it, he did an exhaustive study of shootings including a lot of interviews back in the 70s and early 80's and came up with a new set of techniques which could be used more easily under stress. I was just practicing his punch-fire single hand technique over the weekend. Works! I still use the FBI reload a lot, but swap out to his method as the revolver gets hotter. I think one key with wheelguns is to know and be familiar with all the various reload methods so you can use whatever you need to. Even old-fashioned indexing and reloading by hand, one or two at a time, with your eyes off the revolver and towards the threat. Those strange indentations in the cylinder actually have a purpose, as it turns out.
