It would have to be a pump or semi-auto with an extended magazine tube.
This is a shotgun with an internal barrel diameter (called the "bore) of approximately .410" which shoots a shell which is about .410" in diameter. It is the only shotgun shell size that uses this convention. A 12 gauge shotgun, for example, does not have a bore of "12". A 20 gauge shotgun has a smaller bore than a 12 gauge and a 10 gauge has a bigger bore than a 12. Gauge size is based on the number of lead balls of the bore diameter which are required to make a pound (16 ounces). 10 balls, 12 balls, or 20 balls.
A shotgun with a 12 gauge bore. Gun gauge is an old traditional measurement derived from the number of balls of the size to fit the gun that can be made from one pound of lead. A 12 gauge shotgun will have a bore of .729 inch (18.53 mm).
The bore is the inside of the barrel of the gun. Bore dimension for most rifles is caliber, which is the bore diameter in fractions of an inch or in millimeters. Some older big game rifles had designations such as "12 bore", which is bore diameter the size of a shotgun barrel of the same gauge. Gauge is the number of round balls fitting the bore that can be made from a pound of lead.

The nominal bore size of a 12-gauge shotgun refers to the diameter of the shotgun's barrel, which is approximately 0.729 inches (18.5 mm). The "gauge" system measures the number of lead balls of the bore diameter that can fit into a pound; thus, a 12-gauge shotgun is designed to accommodate 12 lead balls of that diameter. This measurement influences the shotgun's performance, including its shot pattern and recoil.
