A sawed-off break-action shotgun of the type commonly known as a lupara. A sawed-off shotgun (also called a scattergun, sawn-off shotgun, short-barrelled shotgun, shorty, or boom stick) is a type of shotgun with a shorter gun barrel—typically under 18 inches (46 cm)—and often a pistol grip instead of a longer shoulder stock.

Other barrel makers pushed beyond the limits the factory set, and chambered Contender barrels in lighter .308-class cartridges like the .243 Winchester. The Contender can fire .410 bore shotgun shells , either through the .45 Colt /.410 barrel or through a special 21-inch (530 mm) smoothbore shotgun barrel.
For shotguns with fixed chokes integral to the barrel, it is sometimes still possible to change the choke to a tighter choke. This is done by increasing the diameter of the bore inside the barrel for a short length of barrel, while the portion of the barrel and bore nearest the muzzle is left as it was.
The final result is a barrel that is mirror-smooth, and with a consistent or slightly tapering bore. The hand-lapping technique uses a wooden or soft metal rod to pull or push the slug through the bore, while the newer fire-lapping technique uses specially loaded, low-power cartridges to push abrasive-covered soft-lead bullets down the barrel.
