I have had a couple narrow framed guns, 16's, that I could cock both hammers with one hand....But like the quote above says, it aint a war...If I have a dog on point, I generally cock both hammers on the approach...If it's surprise flush, I get one cocked and after I miss the first shot, have plenty of time to cock the other hammer and miss again...Mr. Joe Wood is a fast man with a hammergun...
