Drilling

Drilling

A firearm with three barrels (from the German word drei for three). Typically it has two barrels side by side on the top, with a third rifle barrel underneath. This provides a very versatile firearm capable of taking winged animals as well as big game. It also is useful in jurisdictions where a person is only allowed to own a single firearm.
