Behind the Scenes
The M37A2 is based on the cut down Ithaca Model 37 hunting variant carried Corporal Hicks in Aliens, which also appears in Aliens: Colonial Marines as the Legendary Weapon Hicks' Shotgun. In fact, the model for Hicks' Shotgun appears to be a modified version of the M37A2's, or vice versa. The M37A2's designation also appears to be based on the Ithaca, "M37" being an acronym for "Model 37" (as in real life) and "A2" suggesting that is an improved version of the Ithaca. However, despite being based on the same weapon, Hicks' Shotgun and the M37A2 do not share ammunition and have different round capacities (even though their models both have the same length magazine tubes).
Unlike most of the standard weapons of in Aliens: Colonial Marines, the M37A2 was not developed specifically for the game; it first appeared in the 2011 video game Aliens: Infestation (which is loosely based on Aliens: Colonial Marines) as the "M37A2 Combat Shotgun".
