The Ithaca 37 is a pump-action shotgun made in large numbers for the civilian, military, and police markets. Also known as the Featherlight, it utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements. In addition, the outline of the gun is clean. Finally, since shells load and eject from the bottom, operation of the gun is equally convenient from either side of the gun. This makes the gun popular with left-handed and right-handed shooters alike.
