The Cook submachine gun was an American prototype submachine gun that was designed by Loren Cook.
History
The Cook submachine gun was developed at Benicia Armory in 1950 and promoted by the designer, Loren C. Cook, along with a bullpup automatic rifle that he also designed. The submachine gun was intended for domestic military adoption but little official consideration was given to it. Cook unsuccessfully lobbied to Congress to have his gun adopted, after which he resigned his military post in protest. No further development of the Cook submachine gun was ever made.
Design
The Cook submachine gun was an extremely basic blowback-operated submachine gun offered in 9×19mm and .45 ACP. The construction of the body consisted of a simple tube with a retracting in-line stock; the extant prototypes had no sights. A foregrip was fitted to the barrel. The magazines used were 9mm Sten and .45 M3 magazines respectively.
