Short-barrelled and manually operated (non-semi-automatic) shotguns are not limited as long as the barrel remains unchanged from the original factory length. There is no legal minimum for shotgun barrels as long as they are not handguns; Shotguns as small as 8.5 inches are available in Canada.   What makes a sawed-off shotgun legal?

The restrictions only apply to shotguns, which require a minimum barrel length of 45 cm and a minimum length of 90 cm to be legal. Other shotguns can be of any length.

However, the court also ruled that the Second Amendment did not protect them, as there was no evidence that a sawed-off shotgun was connected in any way to this target.

To convert an existing shoulder shotgun to a short-barreled shotgun or an existing pistol-grip shotgun to “any other weapon,” an individual must pay the standard $200 tax.

Many jurisdictions have a legal minimum length for shotgun barrels so these more hidden shotguns are not available for criminal use. Many gun manufacturers in the United States have not offered sawed-off shotguns to the public since 1934, when shotguns with a barrel length of less than 18 inches were restricted, even if they had already been sold.

The barrel of a shotgun without a tube magazine can be arbitrarily cut long; Shotguns or semi-automatic rifles usually have a barrel magazine attached to the bottom of the barrel, which limits the minimum practical barrel length to about the length of the magazine barrel, unless it is also modified, technically much more difficult than shortening the barrel. Repeating rifles with box magazines do not lose the capacity of the shell during sawing, but are much rarer than those with tube magazines. Shotguns with barrels below the legal minimum length often belong to special categories. The reason some gun owners choose to buy or build sawed-off shotguns is the added convenience of being able to carry or maneuver a more compact litter gun. However, if you don`t need a gun suitable for specific applications, what you can find at your local gun store or sports store will probably suffice. A sawed-off shotgun with exposed and manually stretched hammers and double triggers is known in Italy as lupara (“wolf shooting”) and, although associated with organized crime, was originally used by Sicilian farmers and herders to protect their vineyards and herds of animals.

These are commonly referred to as “entry-level shotguns” because they are often used for forced entry into buildings where easy and short handling is more important than the increased ammunition capacity of a longer shotgun. Penetrating ammunition offers another use for very short shotguns. These cartridges are usually made of sintered powdered metal, but a normal shot or bird shot also works. A shotgun is used to pierce the gun by placing the gun next to a door lock (0 to 2 inches away, 0 to 5 cm) and firing at a 45-degree angle downward through the door between the lock or latch and the door frame.
The impact of the projectile(s) opens a hole through the door and removes the lock or bolt. If the sintered metal or shot quickly detaches through the door and because it has been pointed downwards, the risk of injuring the occupants on the other side of the broken door is minimized.
