Reising M55 Submachine Gun
This video explores the Reising M50 and M55 submachine guns, manufactured by Harrington & Richardson during WWII. Facing a shortage of submachine guns, the US Marine Corps, particularly paratroopers and tank crews, adopted these firearms due to their compactness and lighter weight compared to the Thompson. Chambered in .45 ACP and utilizing a delayed blowback action, the M55 featured a pistol grip and wire folding stock. Despite developing a negative reputation in the Pacific theater due to parts interchangeability issues, fouling susceptibility, and complex disassembly, the Reising was also popular in post-war civilian law enforcement use and remains an affordable military machine gun option today.
