I would imagine that they shot both ways. Whatever came naturally to them. Old newspaper accounts usually tell of using the "duellist" style though. Actually from what I've read, rifles were the more prevalent weapon as they were much more useful and at a dollar a day the average cowpoke couldn't afford to buy much after buying and taking care of a good saddle, boots, and Boss Of The Plains (usually over a period of several months). Luckily they usually wore out at different intervals.
