http://www.patreon.com/ForgottenWeapons Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forgotten-weapons Designed by Aimo Lahti, the Suomi m/31 submachine gun is in my opinion one of the standout submachine guns of the World War Two era. Despite its hefty weight (10.4lb / 4.7kg) and lack of a good pistol grip stock, it still manages to be tremendously controllable and accurate, with a very high rate of fire (about 900 rpm). For a detailed written description of the history and development of the weapon, I would refer you to the excellent article by Jaeger Platoon: http://www.jaegerplatoon.net/MACHINEPISTOLS1.htm If you enjoy Forgotten Weapons, check out its sister channel, InRangeTV! http://www.youtube.com/InRangeTVShow Contact: Forgotten Weapons 6281 N Oracle #36270 Tucson, AZ 85704
