There are a lot of accurate long barrel pistols for hunting, but most of them are essentially made for a rest.
........and as a Sportsman, you owe it to your quarry to use some kind of rest when using a handgun, regardless of barrel length. Also, to those that don't shoot, or shoot very little handgun, most any handgun feels awkward when held out at arms length for more than a few seconds. By the time one has practiced enough with handguns to justify using one for hunting, their wrist and arm strength has increased and they are much more comfortable with the weight of their gun. There's a reason handguns designed specifically for hunting have longer pipes. Think about it.
