I have a question that someone like Brian could maybe shed a little light on. Why didn't the military ever develop a rifle specific to close quarters combat? I, a never having served civilian, suspect a short, large handgun caliber rifle would have been supremely useful in an urban setting-think something along the lines of the Ruger .44 magnum carbine, not a true military rifle as such, but, the closest example of what I am trying to illustrate. I would think a rifle similar to those dimensions, and using .44 magnum or perhaps .45 ammunition would take the fight out of a close quarters situation fairly rapidly and perhaps with more authority than either .22 or .30 caliber weapons. Perhaps one or two guys in a squad using the short, big caliber rifle, would be efficient.
Anyone?

Best,
Ted
