other name for a short barrel shotgun?

AOW or SBS.

A short double is sometimes called "Lupara." Jeff Cooper talks about it here http://dvc.org.uk/jeff/jeff11_11.html, among other places.

Note also that a true carbine is not just a short rifle, but rather a rifle of reduced power.

If the barrel length is 18" or longer, it may be called "a home protection & insurance device". If the barrel length is less than 18" it is called "illegal" by the atf boys in washington. A more polite term would be to call any type of shotgun a "scatter-gun" when liberals are nearby. I know this for a fact from having a table at local gunshows many years ago during the 1980's & 1990's.

For example: "sonic sound suppressor" is more socially acceptable than "silencer"
"home defense scattergun" is more acceptable than "sawed-off"

i know this junk is really an aggravation to true gun-folks, but i have been very successful in turning around many liberals by simply educating them to the truth.

Doesn't shortening the barrel usually reduce the muzzle velocity? Or do you mean that a carbine is specifically a short barrelled, lower power version of a given rifle (as opposed to a gun that was originally designed with a short barrel)?

My dear old Daddy used to call double barrel sawed offs Belly Busters. This of course was back in the day when such talk was allowed, and even laughed at.

Yes indeed that used to be the case, but ask some of the resident handloaders here and they can explain how powder charge and bullet weight can make a shorter barrel shoot to within a few hundred fps of the longer barrel with a "standard" load. Its majic I think.
