The Ithaca Model 37 is an American-made pump-action shotgun chambered for 12 gauge cartridges. It is known for its novel combination ejection/loading port on the bottom of the gun that leaves the sides closed to the elements; since shells load and eject from the bottom, operation of the gun is equally convenient for both right and left hand shooters. This makes the gun popular with left-handed shooters.
Designed in 1933 and first manufactured in 1937, the Model 37 utilizes a novel combination ejection/loading port on the bottom of the gun that leaves the sides of the weapon closed to the elements. Additionally, since shells load and eject from the bottom, operation of the gun is equally convenient for both right- and left-handed users. As a direct result, the weapon is popular with left-handed shooters.
Corporal Hicks notably carried a cut-down version of the Model 37 (fitted with the pistol grip of an MP 40 submachine gun) during the mission to Hadley's Hope, first drawing it when the unit was denied use of their other weapons during the ambush in the Hive. The gun was actually an old family heirloom handed down through generations of Hicks' family, thus explaining the presence of such an antiquated weapon in 2179. After using it to kill a Warrior attempting to board the Marines' APC, the weapon was destroyed by acid and not used again.
A militarized version of the Model 37 "Stakeout" was issued to the United States Colonial Marine Corps, named the M37A2 Pump Shotgun.
- Hicks actor Michael Biehn also used a full-size Model 37 throughout The Terminator, which was written and directed by Aliens director James Cameron.
