I have decided to purchase a Ruger SP 101 stainless 357 magnum, but am not sure if I want the short barrel or the longer one. Use will primarily be in the woods - concealed or not - while also carrying a rifle (usually a Marlin). I often take a GP 100 in the woods by itself, but it's too big and heavy to be secondary to a rifle. What are the pros and cons of each of these barrels?
